-### 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

-- update documentation #2548 #2561 #2569

-Problem: missing eventual group consistency
---------------------------------------------
-
-If group members are concurrently adding new members,
-the new members will miss each other's additions, example:
-
-1. Alice and Bob are in a two-member group
-
-2. Then Alice adds Carol, while concurrently Bob adds Doris
-
-Right now, the group has inconsistent memberships:
-
-- Alice and Carol see a (Alice, Carol, Bob) group
-
-- Bob and Doris see a (Bob, Doris, Alice)
-
-This then leads to "sender is unknown" messages in the chat,
-for example when Alice receives a message from Doris,
-or when Bob receives a message from Carol.
-
-There are also other sources for group membership inconsistency:
-
-- leaving/deleting/adding in larger groups, while being offline,
-  increases chances for inconsistent group membership
-
-- dropped group-membership messages
-
-- group-membership messages landing in "Spam"
-
-
-Note that all these problems (can) also happen with verified groups,
-then raising "false alarms" which could lure people to ignore such issues.
-
-IOW, it's clear we need to do something about it to improve overall
-reliability in group-settings.
-
-
-
-Solution: replay group modification messages on inconsistencies
-------------------------------------------------------------------
-
-For brevity let's abbreviate "group membership modification" as **GMM**.
-
-Delta chat has explicit GMM messages, typically encrypted to the group members
-as seen by the device that sends the GMM. The `Spec <https://github.com/deltachat/deltachat-core-rust/blob/master/spec.md#add-and-remove-members>`_ details the Mime headers and format.
-
-If we detect membership inconsistencies we can resend relevant GMM messages
-to the respective chat.  The receiving devices can process those GMM messages
-as if it would be an incoming message. If for example they have already seen
-the Message-ID of the GMM message, they will ignore the message. It's
-probably useful to record GMM message in their original MIME-format and
-not invent a new recording format. Few notes on three aspects:
-
-- **group-membership-tracking**: All valid GMM messages are persisted in
-  their full raw (signed/encrypted?) MIME-format in the DB. Note that GMM messages
-  already are in the msgs table, and there is a mime_header column which we could
-  extend to contain the raw Mime GMM message.
-
-- **consistency_checking**: If an incoming GMM has a member list which is
-  not consistent with our own view, broadcast a "Group-Member-Correction"
-  message to all members containing a multipart list of GMMs.
-
-- **correcting_memberships**: Upon receiving a Group-Member-Correction
-  message we pass the contained GMMs to the "incoming mail pipeline"
-  (without **consistency_checking** them, to avoid recursion issues)
-
-
-Alice/Carol and Bob/Doris getting on the same page
-++++++++++++++++++++++++++++++++++++++++++++++++++
-
-Recall that Alice/Carol and Bob/Doris had a differening view of
-group membership. With the proposed solution, when Bob receives
-Alice's "Carol added" message, he will notice that Alice (and thus
-also carol) did not know about Doris.  Bob's device sends a
-"Chat-Group-Member-Correction" message containing his own GMM
-when adding Doris. Therefore, the group's membership is healed
-for everyone in a single broadcast message.
-
-Alice might also send a Group-member-Correction message,
-so there is a second chance that the group gets to know all GMMs.
-
-Note, for example, that if for some reason Bobs and Carols provider
-drop GMM messages between them (spam) that Alice and Doris can heal
-it by resending GMM messages whenever they detect them to be out of sync.
-
-
-Discussions of variants
-++++++++++++++++++++++++
-
-- instead of acting on GMM messages we could send corrections
-  for any received message that addresses inconsistent group members but
-  a) this could delay group-membership healing
-  b) could lead to a lot of members sending corrections
-  c) means we might rely on "To-Addresses" which we also like to strike
-     at least for protected chats.
-
-- instead of broadcasting correction messages we could only send it to
-  the sender of the inconsistent member-added/removed message.
-  A receiver of such a correction message would then need to forward
-  the message to the members it thinks also have an inconsistent view.
-  This sounds complicated and error-prone.  Concretely, if Alice
-  receives Bob's "Member-added: Doris" message, then Alice
-  broadcasting the correction message with "Member-added: Carol"
-  would reach all four members, healing group consistency in one step.
-  If Bob meanwhile receives Alice's "Member-Added: Carol" message,
-  Bob would broadcast a correction message to all four members as well.
-  (Imagine a situation where Alice/Bob added Carol/Doris
-  while both being in an offline or bad-connection situation).

-simplify/streamline mark-seen/delete/move/send-mdn job handling
----------------------------------------------------------------
-
-Idea: Introduce a new "msgwork" sql table that looks very
-much like the jobs table but has a primary key "msgid"
-and no job id and no foreign-id anymore. This opens up
-bulk-processing by looking at the whole table and combining
-flag-setting to reduce imap-roundtrips and select-folder calls.
-
-Concretely, these IMAP jobs:
-
-    DeleteMsgOnImap
-    MarkseenMsgOnImap
-    MoveMsg
-
-Would be replaced by a few per-message columns in the new msgwork table:
-
-- needs_mark_seen: (bool) message shall be marked as seen on imap
-- needs_to_move: (bool) message should be moved to mvbox_folder
-- deletion_time: (target_time or 0) message shall be deleted at specified time
-- needs_send_mdn: (bool) MDN shall be sent
-
-The various places that currently add the (replaced) jobs
-would now add/modify the respective message record in the message-work table.
-
-Looking at a single message-work entry conceptually looks like this::
-
-    if msg.server_uid==0:
-        return RetryLater  # nothing can be done without server_uid
-
-    if msg.deletion_time > current_time:
-        imap.mark_delete(msg)  # might trigger early exit with a RetryLater/Failed
-        clear(needs_deletion)
-        clear(mark_seen)
-
-    if needs_mark_seen:
-        imap.mark_seen(msg)    # might trigger early exit with a RetryLater/Failed
-        clear(needs_mark_seen)
-
-    if needs_send_mdn:
-        schedule_smtp_send_mdn(msg)
-        clear(needs_send_mdn)
-
-    if any_flag_set():
-        retrylater
-    # remove msgwork entry from table
-
-
-Notes/Questions:
-
-- it's unclear how much we need per-message retry-time tracking/backoff
-
-- drafting bulk processing algo is useful before
-  going for the implementation, i.e. including select_folder calls etc.
-
-- maybe it's better to not have bools for the flags but
-
-  0 (no change)
-  1 (set the imap flag)
-  2 (clear the imap flag)
-
-  and design such that we can cover all imap flags.
-
-- It might not be neccessary to keep needs_send_mdn state in this table
-  if this can be decided rather when we succeed with mark_seen/mark_delete.

+Installing bindings from source (Updated: 20-Jan-2020)
+=========================================================
+
+Install Rust and Cargo first.  Deltachat needs a specific nightly
+version, the easiest is probably to first install Rust stable from
+rustup and then use this to install the correct nightly version.
+
+Bootstrap Rust and Cargo by using rustup::
+
+   curl https://sh.rustup.rs -sSf | sh
+
+Then GIT clone the deltachat-core-rust repo and get the actual
+rust- and cargo-toolchain needed by deltachat::
+
+   git clone https://github.com/deltachat/deltachat-core-rust
+   cd deltachat-core-rust
+   rustup show
+
+To install the Delta Chat Python bindings make sure you have Python3 installed.
+E.g. on Debian-based systems `apt install python3 python3-pip
+python3-venv` should give you a usable python installation.
+
+Ensure you are in the deltachat-core-rust/python directory, create the
+virtual environment and activate it in your shell::
+
+   cd python
+   python3 -m venv venv  # or: virtualenv venv
+   source venv/bin/activate
+
+You should now be able to build the python bindings using the supplied script::
+
+   ./install_python_bindings.py
+
+The installation might take a while, depending on your machine.
+The bindings will be installed in release mode but with debug symbols.
+The release mode is currently necessary because some tests generate RSA keys
+which is prohibitively slow in non-release mode.
+
+After successful binding installation you can install a few more
+Python packages before running the tests::
+
+    python -m pip install pytest pytest-timeout pytest-rerunfailures requests
+    pytest -v tests
+
+
+running "live" tests with temporary accounts
+---------------------------------------------
+
+If you want to run "liveconfig" functional tests you can set
+``DCC_NEW_TMP_EMAIL`` to:
+
+- a particular https-url that you can ask for from the delta
+  chat devs. This is implemented on the server side via
+  the [mailadm](https://github.com/deltachat/mailadm) command line tool.
+
+- or the path of a file that contains two lines, each describing
+  via "addr=... mail_pw=..." a test account login that will
+  be used for the live tests.
+
+With ``DCC_NEW_TMP_EMAIL`` set pytest invocations will use real
+e-mail accounts and run through all functional "liveconfig" tests.
+
