-
-### 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
-- improve tests #2487 #2491 #2497

-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
--------------------
-
-- 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.
