-### 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

-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
--------------------
-
-- We have one primary self address and any number of secondary self addresses. `is_self_addr()` checks all of them.
-
-- 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
-
-- When we send a message to a group, and the primary address is not a member of a group, but a secondary address is:
-  
-  Add Chat-Group-Member-Removed=<old address> and Chat-Group-Member-Added=<new address> headers to this message
-
-  - On the receiving side, make sure that we accept this (even in verified groups) if the message is signed and the key stayed the same
-
-Other
------
-
-- The user is responsible that messages to the old address arrive at the new address, for example by configuring the old provider to forward all emails to the new one.

-# Webxdc Developer Reference
-
-## Webxdc File Format
-
-- a **Webxdc app** 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 app 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);
-```
-
-Webxdc apps are 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,
-       use this option sparingly to not spam the chat.
-    - `update.summary`: optional, short text, shown beside app 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
-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). 
-
-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 `send_update`) 
-
-- `update.summary`: optional, short text, shown beside app icon (see `send_update`)
-
-
-### 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 App Name"
-```
-
-- **name** - The name of the app.
-  If no name is set or if there is no manifest, the filename is used as the app name.
-
-
-## App Icon
-
-If the ZIP-root contains an `icon.png` or `icon.jpg`,
-these files are used as the icon for the app.
-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 app -
-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)
-
-
-## 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
-- 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.
