+
+### API Changes
+
+- breaking change: removed deaddrop chat #2514 #2563
+
+  Contact request chats are not merged into a single virtual
+  "deaddrop" chat anymore. Instead, they are shown in the chatlist the
+  same way as other chats, but sending of messages to them is not
+  allowed and MDNs are not sent automatically until the chat is
+  "accepted" by the user.
+
+  New API:
+  - `dc_chat_is_contact_request()`: returns true if chat is a contact
+    request.  In this case an option to accept the chat via
+    `dc_accept_chat()` should be shown in the UI.
+  - `dc_accept_chat()`: unblock the chat or accept contact request
+  - `dc_block_chat()`: block the chat, currently works only for mailing
+    lists.
+
+  Removed API:
+  - `dc_create_chat_by_msg_id()`: deprecated 2021-02-07 in favor of
+    `dc_decide_on_contact_request()`
+  - `dc_marknoticed_contact()`: deprecated 2021-02-07 in favor of
+    `dc_decide_on_contact_request()`
+  - `dc_decide_on_contact_request()`: this call requires a message ID
+    from deaddrop chat as input. As deaddrop chat is removed, this
+    call can't be used anymore.
+  - `dc_msg_get_real_chat_id()`: use `dc_msg_get_chat_id()` instead, the
+    only difference between these calls was in handling of deaddrop
+    chat
+  - removed `DC_CHAT_ID_DEADDROP` and `DC_STR_DEADDROP` constants
+
+- breaking change: removed `DC_EVENT_ERROR_NETWORK` and `DC_STR_SERVER_RESPONSE`
+  Instead, there is a new api `dc_get_connectivity()`
+  and `dc_get_connectivity_html()`;
+  `DC_EVENT_CONNECTIVITY_CHANGED` is emitted on changes
+
+- breaking change: removed `dc_accounts_import_account()`
+  Instead you need to add an account and call `dc_imex(DC_IMEX_IMPORT_BACKUP)`
+  on its context
+
+- update account api, 2 new methods:
+  `int dc_all_work_done (dc_context_t* context);`
+  `int dc_accounts_all_work_done (dc_accounts_t* accounts);`
+
+- add api to check if a message was `Auto-Submitted`
+  cffi: `int dc_msg_is_bot (const dc_msg_t* msg);`
+  python: `Message.is_bot()`
+
+- `dc_context_t* dc_accounts_get_selected_account (dc_accounts_t* accounts);`
+  now returns `NULL` if there is no selected account
+
+- added `dc_accounts_maybe_network_lost()` for systems core cannot find out
+  connectivity loss on its own (eg. iOS) #2550
+
+### Added
+- use Auto-Submitted: auto-generated header to identify bots #2502
+- allow sending stickers via repl tool
+- chat: make `get_msg_cnt()` and `get_fresh_msg_cnt()` work for deaddrop chat #2493
+- withdraw/revive own qr-codes #2512
+- add Connectivity view (a better api for getting the connection status) #2319 #2549 #2542
+
+### Changes
+- updated spec: new `Chat-User-Avatar` usage, `Chat-Content: sticker`, structure, copyright year #2480
+- update documentation #2548 #2561 #2569
+- breaking: `Accounts::create` does not also create an default account anymore #2500
+- remove "forwarded" from stickers, as the primary way of getting stickers
+  is by asking a bot and then forwarding them currently #2526
+- mimeparser: use mailparse to parse RFC 2231 filenames #2543
+- allow email addresses without dot in the domain part #2112
+- allow installing lib and include under different prefixes #2558
+- remove counter from name provided by `DC_CHAT_ID_ARCHIVED_LINK` #2566

+- fix database migration #2486
+- do not count hidden messages in get_msg_cnt(). #2493
+- improve drafts detection #2489

+- do not process names, avatars, location XMLs, message signature etc.
+  for duplicate messages #2513

+AEAP MVP
+========
+
+Changes to the UIs
+------------------
+
+- The secondary self addresses (see below) are shown in the UI, but not editable.
+
+- When the user changed the email address in the configure screen, show a dialog to the user, either directly explaining things or with a link to the FAQ (see "Other" below)
+
+Changes in the core
+-------------------
+
+- DONE: We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
+
+- DONE: If the user does a reconfigure and changes the email address, the previous address is added as a secondary self address.
+
+  - don't forget to deduplicate secondary self addresses in case the user switches back and forth between addresses).
+
+  - The key stays the same.
+
+- No changes for 1:1 chats, there simply is a new one. (This works since, contrary to group messages, messages sent to a 1:1 chat are not assigned to the group chat but always to the 1:1 chat with the sender. So it's not a problem that the new messages might be put into the old chat if they are a reply to a message there.)
+
+- When sending a message: If any of the secondary self addrs is in the chat's member list, remove it locally (because we just transitioned away from it). We add a log message for this (alternatively, a system message in the chat would be more visible).
+
+- When receiving a message: If the key exists, but belongs to another address (we may want to benchmark this)
+  AND there is a `Chat-Version` header\
+  AND the message timestamp is newer than the contact's `lastseen` (to prevent changing the address back when messages arrive out of order) (this condition is not that important since we will have eventual consistency even without it):
+
+  Replace the contact in _all_ groups, possibly deduplicate the members list, and add a system message to all of these chats.
+  
+  - Note that we can't simply compare the keys byte-by-byte, since the UID may have changed, or the sender may have rotated the key and signed the new key with the old one.
+
+### Notes:
+  
+- We treat protected and non-protected chats the same
+- We leave the aeap transition statement away since it seems not to be needed, makes things harder on the sending side, wastes some network traffic, and is worse for privacy (since more pepole know what old addresses you had).
+- As soon as we encrypt read receipts, sending a read receipt will be enough to tell a lot of people that you transitioned
+- AEAP will make the problem of inconsistent group state worse, both because it doesn't work if the message is unencrypted (even if the design allowed it, it would be problematic security-wise) and because some chat partners may have gotten the transition and some not. We should do something against this at some point in the future, like asking the user whether they want to add/remove the members to restore consistent group state.
+
+#### Downsides of this design:
+- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
+
+#### Upsides:
+- With this approach, it's easy to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
+- Faster transation: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.
+
+### Alternatives and old discussions/plans:
+
+- Change the contact instead of rewriting the group member lists. This seems to call for more trouble since we will end up with multiple contacts having the same email address.
+
+- If needed, we could add a header a) indicating that the sender did an address transition or b) listing all the secondary (old) addresses.  For now, there is no big enough benefit to warrant introducing another header and its processing on the receiver side (including all the neccessary checks and handling of error cases). Instead, we only check for the `Chat-Version` header to prevent accidental transitions when an MUA user sends a message from another email address with the same key.
+
+- The condition for a transition temporarily was:
+
+  > When receiving a message: If we are going to assign a message to a chat, but the sender is not a member of this chat\
+  > AND the signing key is the same as the direct (non-gossiped) key of one of the chat members\
+  > AND ...
+
+  However, this would mean that in 1:1 messages can't trigger a transition, since we don't assign private messages to the parent chat, but always to the 1:1 chat with the sender.
+  
+<details>
+<summary>Some previous state of the discussion, which temporarily lived in an issue description</summary>
+Summarizing the discussions from https://github.com/deltachat/deltachat-core-rust/pull/2896, mostly quoting @hpk42:
+
+1. (DONE) At the time of configure we push the current primary to become a secondary. 
+
+2. When a message is sent out to a chat, and the message is encrypted, and we have secondary addresses, then we 
+  a) add a protected "AEAP-Replacement" header that contains all secondary addresses 
+  b) if any of the secondary addresses is in the chat's member list, we remove it and leave a system message that we did so
+3. When an encrypted message with a replacement header is received, replace the e-mail address of all secondary contacts (if they exist) with the new primary and drop a sysmessage in all chats the secondary is member off.  This might (in edge cases) result in chats that have two or more contacts with the same e-mail address.  We might ignore this for a first release and just log a warning.  Let's maybe not get hung up on this case before everything else works. 
+
+Notes: 
+- for now we will send out aeap replacement headers forever, there is no termination condition other than lack of secondary addresses.  I think that's fine for now.  Later on we might introduce options to remove secondary addresses but i wouldn't do this for a first release/PR. 
+- the design is resilient against changing e-mail providers from A to B to C and then back to A, with partially updated chats and diverging views from recipients/contacts on this transition.  In the end, you will have a primary and some secondaries, and when you start sending out messages everybody will eventually synchronize when they receive the current state of primaries/secondaries. 
+- of course on incoming message for need to check for each stated secondary address in the replacement header that it uses the same signature as the signature we verified as valid with the incoming message  **-->  Also we have to somehow make sure that the signing key was not just gossiped from some random other person in some group.**
+- there are no extra flags/columns in the database needed (i hope) 
+
+#### Downsides of the chosen approach:
+- Inconsistent group state: Suppose Alice does an AEAP transition and sends a 1:1 message to Bob, so Bob rewrites Alice's contact. Alice, Bob and Charlie are together in a group. Before Alice writes to this group, Bob and Charlie will have different membership lists, and Bob will send messages to Alice's new address, while Charlie will send them to her old address.
+- There will be multiple contacts with the same address in the database. We will have to do something against this at some point.
+
+The most obvious alternative would be to create a new contact with the new address and replace the old contact in the groups.
+
+#### Upsides:
+- With this approach, it's easier to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
+- (Also, less important: Slightly faster transation: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.)
+- It's easier to implement (if too many problems turn up, we can still switch to another approach and didn't wast that much development time.)

+# Webxdc Developer Reference
+
+(This document may eventually be merged with the [webxdc guidebook](https://deltachat.github.io/webxdc_docs/), where you may currently find other useful information.)
+
+## Webxdc File Format
+
+- a **Webxdc** is a **ZIP-file** with the extension `.xdc`
+- the ZIP-file must use the default compression methods as of RFC 1950,
+  this is "Deflate" or "Store"
+- the ZIP-file must contain at least the file `index.html`
+- if the Webxdc is started, `index.html` is opened in a restricted webview
+  that allow accessing resources only from the ZIP-file
+
+
+## Webxdc API
+
+There are some additional APIs available once `webxdc.js` is included
+(the file will be provided by the concrete implementations,
+no need to add `webxdc.js` to your ZIP-file):
+
+```html
+<script src="webxdc.js"></script>
+```
+
+### sendUpdate()
+
+```js
+window.webxdc.sendUpdate(update, descr);
+```
+
+A Webxdc is usually shared in a chat and run independently on each peer.
+To get a shared state, the peers use `sendUpdate()` to send updates to each other.
+
+- `update`: an object with the following properties:  
+    - `update.payload`: any javascript primitive, array or object.
+    - `update.info`: optional, short, informational message that will be added to the chat,
+       eg. "Alice voted" or "Bob scored 123 in MyGame".
+       usually only one line of text is shown
+       and if there are series of info messages, older ones may be dropped.
+       use this option sparingly to not spam the chat.
+    - `update.document`: optional, name of the document in edit,
+       must not be used eg. in games where the Webxdc does not create documents
+    - `update.summary`: optional, short text, shown beside Webxdc icon;
+       it is recommended to use some aggregated value,  eg. "8 votes", "Highscore: 123"
+
+- `descr`: short, human-readable description what this update is about.
+  this is shown eg. as a fallback text in an email program.
+
+All peers, including the sending one,
+will receive the update by the callback given to `setUpdateListener()`.
+
+There are situations where the user cannot send messages to a chat,
+eg. if the webxdc instance comes as a contact request or if the user has left a group.
+In these cases, you can still call `sendUpdate()`,
+however, the update won't be sent to other peers
+and you won't get the update by `setUpdateListener()`.
+
+
+### setUpdateListener()
+
+```js
+let promise = window.webxdc.setUpdateListener((update) => {}, serial);
+```
+
+With `setUpdateListener()` you define a callback that receives the updates
+sent by `sendUpdate()`. The callback is called for updates sent by you or other peers.
+The `serial` specifies the last serial that you know about (defaults to 0). 
+The returned promise resolves when the listener has processed all the update messages known at the time when  `setUpdateListener` was called. 
+
+Each `update` which is passed to the callback comes with the following properties: 
+
+- `update.payload`: equals the payload given to `sendUpdate()`
+
+- `update.serial`: the serial number of this update.
+  Serials are larger `0` and newer serials have higher numbers.
+  There may be gaps in the serials
+  and it is not guaranteed that the next serial is exactly incremented by one.
+
+- `update.max_serial`: the maximum serial currently known.
+  If `max_serial` equals `serial` this update is the last update (until new network messages arrive).
+
+- `update.info`: optional, short, informational message (see `sendUpdate()`)
+
+- `update.document`: optional, document name as set by the sender, (see `sendUpdate()`),
+  implementations show the document name eg. beside the app icon or in the title bar
+
+- `update.summary`: optional, short text, shown beside icon (see `sendUpdate()`)
+
+
+### selfAddr
+
+```js
+window.webxdc.selfAddr
+```
+
+Property with the peer's own address.
+This is esp. useful if you want to differ between different peers -
+just send the address along with the payload,
+and, if needed, compare the payload addresses against selfAddr() later on.
+
+
+### selfName
+
+```js
+window.webxdc.selfName
+```
+
+Property with the peer's own name.
+This is name chosen by the user in their settings,
+if there is nothing set, that defaults to the peer's address.
+
+
+## manifest.toml
+
+If the ZIP-file contains a `manifest.toml` in its root directory,
+some basic information are read and used from there.
+
+the `manifest.toml` has the following format
+
+```toml
+name = "My Name"
+source_code_url = "https://example.org/orga/repo"
+```
+
+- `name` - The name of the Webxdc.
+  If no name is set or if there is no manifest, the filename is used as the Webxdc name.
+
+- `source_code_url` - Optional URL where the source code of the Webxdc and maybe other information can be found.
+  UI may make the url accessible via a "Help" menu in the Webxdc window.
+
+
+## Webxdc Icon
+
+If the ZIP-root contains an `icon.png` or `icon.jpg`,
+these files are used as the icon for the Webxdc.
+The icon should be a square at reasonable width/height;
+round corners etc. will be added by the implementations as needed.
+If no icon is set, a default icon will be used.
+
+
+## Webxdc Examples
+
+The following example shows an input field and  every input is show on all peers.
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="utf-8"/>
+    <script src="webxdc.js"></script>
+  </head>
+  <body>
+    <input id="input" type="text"/>
+    <a href="" onclick="sendMsg(); return false;">Send</a>
+    <p id="output"></p>
+    <script>
+    
+      function sendMsg() {
+        msg = document.getElementById("input").value;
+        window.webxdc.sendUpdate({payload: msg}, 'Someone typed "'+msg+'".');
+      }
+    
+      function receiveUpdate(update) {
+        document.getElementById('output').innerHTML += update.payload + "<br>";
+      }
+    
+      window.webxdc.setUpdateListener(receiveUpdate, 0);
+    </script>
+  </body>
+</html>
+```
+
+[Webxdc Development Tool](https://github.com/deltachat/webxdc-dev)
+offers an **Webxdc Simulator** that can be used in many browsers without any installation needed.
+You can also use that repository as a template for your own Webxdc -
+just clone and start adapting things to your need.
+
+
+### Advanced Examples
+
+- [2048](https://github.com/adbenitez/2048.xdc)
+- [Draw](https://github.com/adbenitez/draw.xdc)
+- [Poll](https://github.com/r10s/webxdc-poll/)
+- [Tic Tac Toe](https://github.com/Simon-Laux/tictactoe.xdc)
+- Even more with [Topic #webxdc on Github](https://github.com/topics/webxdc) or in the [webxdc GitHub organization](https://github.com/webxdc)
+
+
+## Closing Remarks
+
+- older devices might not have the newest js features in their webview,
+  you may want to transpile your code down to an older js version eg. with https://babeljs.io
+- viewport and scaling features are implementation specific,
+  if you want to have an explicit behavior, you can add eg.
+  `<meta name="viewport" content="initial-scale=1; user-scalable=no">` to your Webxdc
+- the `<title>` tag should not be used and its content is usually not displayed;
+  instead, use the `name` property from `manifest.toml`
+- there are tons of ideas for enhancements of the API and the file format,
+  eg. in the future, we will may define icon- and manifest-files,
+  allow to aggregate the state or add metadata.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+[![JavaScript Style Guide](https://img.shields.io/badge/code_style-prettier-brightgreen.svg)](https://prettier.io)
+
+`deltachat-node` primarily aims to offer two things:
+
+- A high level JavaScript api with syntactic sugar
+- A low level c binding api around  [`deltachat-core-rust`](..)
+
+This code used to live at [`deltachat-node`](https://github.com/deltachat/deltachat-node)

+
+</details>
+
+## Install
+
+By default the installation will build try to use the bundled prebuilds in the
+npm package. If this fails it falls back to compile `../deltachat-core-rust` from
+this repository, using `scripts/rebuild-core.js`.
+
+To install from npm use:
+
+```
+npm install deltachat-node
+```
+
+## Dependencies
+
+- Nodejs >= `v16.0.0`
+- rustup (optional if you can't use the prebuilds)
+
+> On Windows, you may need to also install **Perl** to be able to compile deltachat-core.
+
+## Build from source
+
+If you want to build from source, make sure that you have `rustup` installed.
+You can either use `npm install deltachat-node --build-from-source` to force
+building from source or clone this repository and follow this steps:
+
+1. `git clone https://github.com/deltachat/deltachat-core-rust.git`
+2. `cd deltachat-core-rust`
+3. `npm i`
+4. `npm run build`
+
+> Our `package.json` file is located in the root directory of this repository,
+> not inside this folder. (We need this in order to include the rust source
+> code in the npm package.)
+
+### Use build-from-source in deltachat-desktop
+
+If you want to use the manually built node bindings in the desktop client (for
+example), you can follow these instructions:
+
+First clone the
+[deltachat-desktop](https://github.com/deltachat/deltachat-desktop) repository,
+e.g. with `git clone https://github.com/deltachat/deltachat-desktop`.
+
+Then you need to make sure that this directory is referenced correctly in
+deltachat-desktop's package.json. You need to change
+`deltachat-desktop/package.json` like this:
+
+```
+diff --git i/package.json w/package.json
+index 45893894..5154512c 100644
+--- i/package.json
++++ w/package.json
+@@ -83,7 +83,7 @@
+     "application-config": "^1.0.1",
+     "classnames": "^2.3.1",
+     "debounce": "^1.2.0",
+-    "deltachat-node": "1.79.3",
++    "deltachat-node": "file:../deltachat-core-rust/",
+     "emoji-js-clean": "^4.0.0",
+     "emoji-mart": "^3.0.1",
+     "emoji-regex": "^9.2.2",
+```
+
+Then, in the `deltachat-desktop` repository, run:
+
+1. `npm i`
+2. `npm run build`
+3. And `npm run start` to start the newly built client.
+
+### Workaround to build for x86_64 on Apple's M1
+
+deltachat doesn't support universal (fat) binaries (that contain builds for both cpu architectures) yet, until it does you can use the following workaround to get x86_64 builds:
+
+```
+$ fnm install 17 --arch x64
+$ fnm use 17
+$ node -p process.arch
+# result should be x64
+$ cd deltachat-core-rust && rustup target add x86_64-apple-darwin && cd -
+$ git apply patches/m1_build_use_x86_64.patch
+$ CARGO_BUILD_TARGET=x86_64-apple-darwin npm run build
+$ npm run test
+```
+
+(when using [fnm](https://github.com/Schniz/fnm) instead of nvm, you can select the architecture)
+If your node and electron are already build for arm64 you can also try bulding for arm:
+
+```
+$ fnm install 16 --arch arm64
+$ fnm use 16
+$ node -p process.arch
+# result should be arm64
+$ npm_config_arch=arm64 npm run build
+$ npm run test
+```
+
+## Usage
+
+```js
+const { Context } = require('deltachat-node')
+
+const opts = {
+  addr: '[email]',
+  mail_pw: '[password]',
+}
+
+const contact = '[email]'
+
+async function main() {
+  const dc = Context.open('./')
+  dc.on('ALL', console.log.bind(null, 'core |'))
+
+  try {

+
+### Generating Docs
+
+We are curently migrating to automaticaly generated documentation.
+You can find the old documentation at [old_docs](./old_docs).
+
+to generate the documentation, run:
+
+```
+npx typedoc
+```
+
+The resulting documentation can be found in the `docs/` folder.
+An online version can be found under [js.delta.chat](https://js.delta.chat).
+
+## Developing
+
+### Tests and Coverage
+
+Running `npm test` ends with showing a code coverage report, which is produced by [`nyc`](https://github.com/istanbuljs/nyc#readme).
+
+![test output](images/tests.png)
+
+The coverage report from `nyc` in the console is rather limited. To get a more detailed coverage report you can run `npm run coverage-html-report`. This will produce a html report from the `nyc` data and display it in a browser on your local machine.
+
+To run the integration tests you need to set the `DCC_NEW_TMP_EMAIL` environment variables. E.g.:
+
+```
+$ export DCC_NEW_TMP_EMAIL=https://testrun.org/new_email?t=[token]
+$ npm run test
+```
+
+### Scripts
+
+We have the following scripts for building, testing and coverage:
+
+- `npm run coverage` Creates a coverage report and passes it to `coveralls`. Only done by `Travis`.
+- `npm run coverage-html-report` Generates a html report from the coverage data and opens it in a browser on the local machine.
+- `npm run generate-constants` Generates `constants.js` and `events.js` based on the `deltachat-core-rust/deltachat-ffi/deltachat.h` header file.
+- `npm install` After dependencies are installed, runs `node-gyp-build` to see if the native code needs to be rebuilt.
+- `npm run build` Rebuilds all code.
+- `npm run build:core` Rebuilds code in `deltachat-core-rust`.
+- `npm run build:bindings` Rebuilds the bindings and links with `deltachat-core-rust`.
+- `ǹpm run clean` Removes all built code
+- `npm run prebuildify` Builds prebuilt binary to `prebuilds/$PLATFORM-$ARCH`. Copies `deltachat.dll` from `deltachat-core-rust` for windows.
+- `npm run download-prebuilds` Downloads all prebuilt binaries from github before `npm publish`.
+- `npm test` Runs `standard` and then the tests in `test/index.js`.
+- `npm run test-integration` Runs the integration tests.
+- `npm run hallmark` Runs `hallmark` on all markdown files.
+
+### Releases
+
+The following steps are needed to make a release:
+
+1. Wait until `pack-module` github action is completed
+2. Run `npm publish https://download.delta.chat/node/deltachat-node-v1.x.x.tar.gz` to publish it to npm. You probably need write rights to npm.
