## [2.61.0] - 2026-09-21

### API-Changes

- add `init_transports()` for multi-relay onboarding.
- add JSON-RPC API `is_sending_finished()`.
- [**breaking**] remove verification methods from the FFI and JSON-RPC APIs.
  - `dc_contact_is_verified()` and `dc_contact_get_verifier_id()` are removed.
  - the JSON-RPC Contact object loses the `isVerified` and `verifierId` fields. A bot reading `snapshot.is_verified` now gets an `AttributeError` at runtime.
  - the Python bindings lose `Contact.is_verified()` and `Contact.get_verifier()`.
  - `DC_STR_CONTACT_VERIFIED` (35) is removed, so UIs should stop registering a translation for it. A stock id core does not know is logged and otherwise ignored, so an un-updated client keeps working.
- [**breaking**] remove default value for "addr" config.
- [**breaking**] remove `addr` field from Account objects in JSON-RPC APIs.
  - `list_transports()` should be used instead.
- [**breaking**] remove `is_chatmail` and the XCHATMAIL capability.
  - `is_chatmail` is no longer a known config key.
- [**breaking**] remove `Contact.get_name_n_addr()` and related APIs.
  - `dc_contact_get_name_n_addr()` CFFI is removed
  - JSON-RPC contact objects don't have nameAndAddr field anymore
- [**breaking**] replace `was_seen_recently` by `freshness` in contact object.
  - use contact's `freshness` instead of `seen_recently`

### Fixes

- always emit `AccountsBackgroundFetchDone`.
- make `background_fetch` not wait on or trigger SMTP connections.
- do not send a sync message when changing `configured_addr`.
- emit `SmtpMessageSent` event after deleting the message from SMTP queue.
- don't use extra STUN nine server for fallback.
- use `max_smtp_rcpt_to` chunking for the actual transport we are sending from.
- use correct `From` address when sending MDNs.
- use correct address for Bcc-self in unencrypted mails.
- don't emit configure progress events during background relay additions.

### Features / Changes

- better quality of image recoding ([#8682](https://github.com/chatmail/core/pull/8682)).
- perform background fetch from all transports.
- queue messages for SMTP before encryption.
- [**breaking**] stop tracking contact verification.
  - the statistics JSON sent to the self-reporting-bot on Android changes: Contacts have `encrypted` instead of `verified` and lose `transitive_chain` properties and message stats have `encrypted` instead of `verified` and `unverified_encrypted`, and securejoin invites lose `already_verified`. The collecting bot stores incoming reports verbatim but analysis will have to make sense of older and newer reports.
- remove last usage of XDELTAPUSH capability.
- base server-side message deletion on `force_encryption`.
- do not restart I/O when setting `configured_addr`.
- do not use ConfiguredAddr when connecting to SMTP.
- mark autorelays for relay operators ([#8701](https://github.com/chatmail/core/pull/8701)).

- remove `protect_autocrypt` setting.

### Miscellaneous Tasks

- cleanup "primary" wording in comments.
- update rustls to 0.23.45.

- substitute configure progress macro with simple function call.

### Tests

- cleanup `get_smtp_rows_for_msg()`.
- cross-core securejoin invites for every chat type.
- explicitly empty url in appversion updates ([#8702](https://github.com/chatmail/core/pull/8702)).
- do not talk about "inconsistent key state" in `test_securejoin_after_contact_resetup`.
- rename `test_aeap_transition_{0,1}` to `test_aeap_transition_{single,group}`.
- do not fetch all messages when `direct_imap` is created.
- `direct_imap`: always pass `mark_seen=False` to fetch().
- add pseudo transport explicitly rather than by setting ConfiguredAddr.

## [2.60.0] - 2026-09-11

### API-Changes

- [**breaking**] remove a relay immediately instead of unpublishing it.
  - `set_transport_unpublished()` is removed: UIs call `delete_transport()` when the user removes a relay.
  - `list_transports_ex()` and the `TransportListEntry` type are removed: use `list_transports()`.
  - `delete_transport()` no longer refuses to remove the primary transport: it refuses only to remove the last one and re-elects the sending transport as needed.
  - `TransportsModified` is now also emitted on the device modifying the transports, not only on devices applying the synced change.
- [**breaking**] do not load webxdc icon if it has too large dimensions.
  - `get_webxdc_blob()` may fail to load `icon.png` or `icon.jpg` if image dimensions are too large.
    Fixing the issue discovered by https://github.com/Sergei768
- Generate JSON-RPC headers at build time ([#8350](https://github.com/chatmail/core/pull/8350)).
- Generate Qt JSON-RPC bindings ([#8330](https://github.com/chatmail/core/pull/8330)).

## [2.0.0] - 2025-07-09

This release changes the way the core handles contact keys.
Instead of tracking OpenPGP keys corresponding to the
contacts in [Autocrypt](https://autocrypt.org/) peerstate,
the core creates a new "key-contact" for each known public key.
Reception of a message signed with a new unknown key
no longer results in warnings about setup changes,
but creates a new contact and a new 1:1 chat if necessary.
Additionally, there are "address-contacts" corresponding
to the e-mail addresses.

### Features / Changes

- Key-contacts ([#6796](https://github.com/chatmail/core/pull/6796), [#6941](https://github.com/chatmail/core/pull/6941)).
- Increase event channel size from 1000 to 10000.
- Minimize the amount of data preserved for trashed messages.
- Show broadcast channels in their own, proper "Channel" chat ([#6901](https://github.com/chatmail/core/pull/6901), [#6975](https://github.com/chatmail/core/pull/6975)).
- Check images passed as `File` before making them `Image`.

### API-Changes

- [**breaking**] Add InBroadcastChannel, OutBroadcastChannel chattypes, add create_broadcast_channel() ([#6901](https://github.com/chatmail/core/pull/6901)).
- deltachat-rpc-client: Add Message.get_read_receipts().

### Fixes

- Remove display name from get_info(). This information usually goes at the top of the log and we don't want users to include it in bug reports.
- Wait for scheduler tasks shutdown in parallel.
- Update deltachat-repl help and autocomplete to match implementation ([#6978](https://github.com/chatmail/core/pull/6978), ([#6979](https://github.com/chatmail/core/pull/6979)).
- Send Autocrypt header in MDNs. This is needed to assign MDNs to key-contacts.
- Prefer encrypted List-Id header ([#6983](https://github.com/chatmail/core/pull/6983)).
- Treat "tgs" as Viewtype::File.
- Treat and send images that can't be decoded as Viewtype::File.
- Decide on filename used for sending depending on the original Viewtype.
- Migrate_key_contacts(): Remove "id>9" from encrypted messages SELECT.
- Save msgs to key-contacts migration state and run migration periodically ([#6956](https://github.com/chatmail/core/pull/6956)).
- Do not try to lookup key-contacts for unencrypted 1:1 messages.
- Add query to post request for account creation ([#6989](https://github.com/chatmail/core/pull/6989)).

## [1.134.0] - 2024-01-31

### API-Changes

- [**breaking**] JSON-RPC: device message api now requires `Option<MessageData>` instead of `String` for the message ([#5211](https://github.com/chatmail/core/pull/5211)).
- CFFI: add `dc_accounts_background_fetch` and event `DC_EVENT_ACCOUNTS_BACKGROUND_FETCH_DONE`.

## [1.133.1] - 2024-01-21

### API-Changes

- Add `is_bot` to cffi and jsonrpc ([#5197](https://github.com/chatmail/core/pull/5197)).

### Features / Changes

- Add system message when provider does not allow unencrypted messages ([#5195](https://github.com/chatmail/core/pull/5195)).

### Fixes

- `Chat::send_msg`: Remove encryption-related params from already sent message. This allows to send received encrypted `dc_msg_t` object to unencrypted chat, e.g. in a Python bot.
- Set message download state to Failure on IMAP errors. This avoids partially downloaded messages getting stuck in "Downloading..." state without actually being in a download queue.
- BCC-to-self even if server deletion is set to "at once". This is a workaround for SMTP servers which do not return response in time, BCC-self works as a confirmation that message was sent out successfully and does not need more retries.
- node: Run tests with native ESM modules instead of `esm` ([#5194](https://github.com/chatmail/core/pull/5194)).
- Use Quoted-Printable MIME encoding for the text part ([#3986](https://github.com/chatmail/core/pull/3986)).

### Tests

## [1.133.0] - 2024-01-14

### Features / Changes

- Securejoin protocol implementation refinements
  - Track forward and backward verification separately ([#5089](https://github.com/chatmail/core/pull/5089)) to avoid inconsistent states.
  - Mark 1:1 chat as verified for Bob early. 1:1 chat with Alice is verified as soon as Alice's key is verified rather than at the end of the protocol.
- Put Message-ID into hidden headers and take it from there on receiver ([#4798](https://github.com/chatmail/core/pull/4798)). This works around servers which generate their own Message-ID and overwrite the one generated by Delta Chat.
- deltachat-repl: Enable INFO logging by default and add timestamps.
- Add `ConfigSynced` (`DC_EVENT_CONFIG_SYNCED`) event which is emitted when configuration is changed via synchronization message or synchronization message for configuration is sent. UI may refresh elements based on the configuration key which is a part of the event.
- Sync contact creation/rename across devices ([#5163](https://github.com/chatmail/core/pull/5163)).
- Encrypt MDNs ([#5175](https://github.com/chatmail/core/pull/5175)).
- Only try to configure non-strict TLS checks if explicitly set ([#5181](https://github.com/chatmail/core/pull/5181)).

- Update securejoin link in `standards.md` from <https://countermitm.readthedocs.io/> to <https://securejoin.readthedocs.io>.
- Restore "Constants" page in Doxygen >=1.9.8

### Fixes

- imap: Limit the rate of LOGIN attempts rather than connection attempts. This is to avoid having to wait for rate limiter right after switching from a bad or offline network to a working network while still guarding against reconnection loop.
- Do not ignore `peerstate.save_to_db()` errors.
- securejoin: Mark 1:1s as protected regardless of the Config::VerifiedOneOnOneChats.
- Delete received outgoing messages from SMTP queue ([#5115](https://github.com/chatmail/core/pull/5115)).
- imap: Fail fast on `LIST` errors to avoid busy loop when connection is lost.
- Split SMTP jobs already in `chat::create_send_msg_jobs()` ([#5115](https://github.com/chatmail/core/pull/5115)).
- Do not remove contents from unencrypted [Schleuder](https://schleuder.org/) mailing lists messages.
- Reset message error when scheduling resending ([#5119](https://github.com/chatmail/core/pull/5119)).
- Emit events more reliably when starting and stopping I/O ([#5101](https://github.com/chatmail/core/pull/5101)).
- Fix timestamp of chat protection info message for correct message ordering after restoring a backup ([#5088](https://github.com/chatmail/core/pull/5088)).

### Refactor

- sql: Recreate `config` table with UNIQUE constraint.
- sql: Recreate `keypairs` table to remove unused `addr` and `created` fields and move `is_default` flag to `config` table.
- Send `Secure-Join-Fingerprint` only in `*-request-with-auth`.

### Tests

- Add `test_utils::sync()`.
- Test inserting lots of webxdc updates.
- Split `test_sync_alter_chat()` into smaller tests.

## [1.131.8] - 2023-11-27

### Fixes

- `deltachat-rpc-client`: Run `deltachat-rpc-server` in its own process group. This prevents reception of `SIGINT` by the server when the bot is terminated with `^C`.
- python: Don't automatically set the displayname to "bot" when setting log level.
- Don't update `timestamp`, `timestamp_rcvd`, `state` when replacing partially downloaded message ([#4700](https://github.com/chatmail/core/pull/4700)).
- Assign encrypted partially downloaded group messages to 1:1 chat ([#4757](https://github.com/chatmail/core/pull/4757)).

### API-Changes

- [**breaking**] Return `DC_CONTACT_ID_SELF` from `dc_contact_get_verifier_id()` for directly verified contacts.
- Deprecate `dc_contact_get_verifier_addr`.
- python: use `dc_contact_get_verifier_id()`. `get_verifier()` returns a Contact rather than an address now.
- Deprecate `get_next_media()`.
- Ignore public key argument in `dc_preconfigure_keypair()`. Public key is extracted from the private key.

### Fixes

- Wrap base64-encoded parts to 76 characters.

- Do not trash messages with attachments and no text when `location.kml` is attached ([#4749](https://github.com/chatmail/core/issues/4749)).
- Initialise `last_msg_id` to the highest known row id. This ensures bots migrated from older version to `dc_get_next_msgs()` API do not process all previous messages from scratch.
- Do not put the status footer into reaction MIME parts.
- Ignore special chats in `get_similar_chat_ids()`. This prevents trash chat from showing up in similar chat list ([#4756](https://github.com/chatmail/core/issues/4756)).
- Cap percentage in connectivity layout to 100% ([#4765](https://github.com/chatmail/core/pull/4765)).
- Add Let's Encrypt root certificate to `reqwest`. This should allow scanning `DCACCOUNT` QR-codes on older Android phones when the server has a Let's Encrypt certificate.
- deltachat-rpc-client: Increase stdio buffer to 64 MiB to avoid Python bots crashing when trying to load large messages via a JSON-RPC call.
- Add `protected-headers` directive to Content-Type of encrypted messages with attachments ([#2302](https://github.com/chatmail/core/issues/2302)). This makes Thunderbird show encrypted Subject for Delta Chat messages.
- webxdc: Reset `document.update` on forwarding. This fixes the test `test_forward_webxdc_instance()`.

### Features / Changes

- `lookup_chat_by_reply()`: Skip undecipherable parent messages created by older versions ([#4676](https://github.com/chatmail/core/pull/4676)).
- imex: Use "default" in the filename of the default key.

### Miscellaneous Tasks

## [1.117.0] - 2023-06-15

### Features

- New group membership update algorithm.

  New algorithm improves group consistency
  in cases of missing messages,
  restored old backups and replies from classic MUAs.

- Add `DC_EVENT_MSG_DELETED` event.

  This event notifies the UI about the message
  being deleted from the messagelist, e.g. when the message expires
  or the user deletes it.

### Fixes

- Emit `DC_EVENT_MSGS_CHANGED` without IDs when the message expires.

  Specifying msg IDs that cannot be loaded in the event payload
  results in an error when the UI tries to load the message.
  Instead, emit an event without IDs
  to make the UI reload the whole messagelist.

- Ignore address case when comparing the `To:` field to `Autocrypt-Gossip:`.

  This bug resulted in failure to propagate verification
  if the contact list already contained a new verified group member
  with a non-lowercase address.

- dehtml: skip links with empty text.

  Links like `<a href="https://delta.chat/"></a>` in HTML mails are now skipped
  instead of being converted to a link without a label like `[](https://delta.chat/)`.

- dehtml: Do not insert unnecessary newlines when parsing `<p>` tags.

- Update from yanked `libc` 0.2.145 to 0.2.146.
- Update to async-imap 0.9.0 to remove deprecated `ouroboros` dependency.

### API-Changes

- Emit `DC_EVENT_MSGS_CHANGED` per chat when messages are deleted.

  Previously a single event with zero chat ID was emitted.

- python: make `Contact.is_verified()` return bool.

- rust: add API endpoint `get_status_update` ([#4468](https://github.com/chatmail/core/pull/4468)).

- rust: make `WebxdcManifest` type public.

### Fixes

- Fetch at most 100 existing messages even if EXISTS was not received.
- Delete `smtp` rows when message sending is canceled.

### Changes

- Improve SMTP logging.

## [1.114.0] - 2023-04-24

### Changes
- JSON-RPC: Use long polling instead of server-sent notifications to retrieve events.
  This better corresponds to JSON-RPC 2.0 server-client distinction
  and is expected to simplify writing new bindings
  because dispatching events can be done on higher level.
- JSON-RPC: TS: Client now has a mandatory argument whether you want to start listening for events.

### Fixes
- JSON-RPC: do not print to stdout on failure to find an account.


## [1.113.0] - 2023-04-18

### Added
- New JSON-RPC API `can_send()`.
- New `dc_get_next_msgs()` and `dc_wait_next_msgs()` C APIs.
  New `get_next_msgs()` and `wait_next_msgs()` JSON-RPC API.
  These APIs can be used by bots to get all unprocessed messages
  in the order of their arrival and wait for them without relying on events.
- New Python bindings API `Account.wait_next_incoming_message()`.
- New Python bindings APIs `Message.is_from_self()` and `Message.is_from_device()`.

### Changes
- Increase MSRV to 1.65.0. #4236
- Remove upper limit on the attachment size. #4253
- Update rPGP to 0.10.1. #4236
- Compress HTML emails stored in the `mime_headers` column of the database.
- Strip BIDI characters in system messages, files, group names and contact names. #3479
- Use release date instead of the provider database update date in `maybe_add_time_based_warnings()`.
- Gracefully terminate `deltachat-rpc-server` on Ctrl+C (`SIGINT`), `SIGTERM` and EOF.
- Async Python API `get_fresh_messages_in_arrival_order()` is deprecated
  in favor of `get_next_msgs()` and `wait_next_msgs()`.
- Remove metadata from avatars and JPEG images before sending. #4037
- Recode PNG and other supported image formats to JPEG if they are > 500K in size. #4037

### Fixes

## [1.112.3] - 2023-03-30

### Fixes
- `transfer::get_backup` now frees ongoing process when canceled. #4249

## [1.112.2] - 2023-03-30

### Changes
- Update iroh, remove `default-net` from `[patch.crates-io]` section.
- transfer backup: Connect to multiple provider addresses concurrently.  This should speed up connection time significantly on the getter side.  #4240
- Make sure BackupProvider is canceled on drop (or `dc_backup_provider_unref`).  The BackupProvider will now always finish with an IMEX event of 1000 or 0, previously it would sometimes finished with 1000 (success) when it really was 0 (failure). #4242

### Fixes
- Do not return media from trashed messages in the "All media" view. #4247

## [1.112.1] - 2023-03-27

  `dc_start_io()` can now be called at any time without harm. #4138
- Pick up system's light/dark mode in generated message HTML. #4150
- More accurate `maybe_add_bcc_self` device message text. #4175
- "Full message view" not needed because of footers that go to contact status. #4151

- Print deltachat-repl errors with causes. #4166

### Fixes
- Fix segmentation fault if `dc_context_unref()` is called during
  background process spawned by `dc_configure()` or `dc_imex()`
  or `dc_jsonrpc_instance_t` is unreferenced
  during handling the JSON-RPC request. #4153

## 1.110.0

### Changes
- use transaction in `Contact::add_or_lookup()` #4059

  connection page cache is reused more often.
  This speeds up tests by 28%, real usage will have lower speedup. #4065

- Fix a problem with Gmail where (auto-)deleted messages would get archived instead of deleted.
  Move them to the Trash folder for Gmail which auto-deletes trashed messages in 30 days #3972
- Clear config cache after backup import. This bug sometimes resulted in the import to seemingly work at first. #4067
- Update timestamps in `param` columns with transactions. #4083

## 1.57.0

### 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);`

  crate from @dignifiedquire. thanks @link2xt. 

- introduce per-contact profile images to send out 
  own profile image heuristically, and fix sending
  out of profile images in "in-prepare" groups. 
  this also extends the Chat-spec that is maintained
  in core to specify Chat-Group-Image and Chat-Group-Avatar
  headers. thanks @r10s and @hpk42.

- fix merging of protected headers from the encrypted
  to the unencrypted parts, now not happening recursively
  anymore.  thanks @hpk and @r10s

- fix/optimize autocrypt gossip headers to only get 
  sent when there are more than 2 people in a chat. 
  thanks @link2xt

- fix displayname to use the authenticated name 
  when available (displayname as coming from contacts 
  themselves). thanks @simon-laux

- introduce preliminary support for offline autoconfig 
  for nauta provider. thanks @hpk42 @r10s

## 1.0.0-beta.15

  if we cannot terminate the IDLE IMAP protocol. @hpk42 @link2xt

- fix incoming multipart/mixed containing html, to show up as
  attachments again.  Fixes usage for simplebot which sends html
  files for users to interact with the bot. @adbenitez @hpk42 

- refinements to internal autocrypt-handling code, do not send
  prefer-encrypt=nopreference as it is the default if no attribute
  is present.  @linkxt 

- simplify, modularize and rustify several parts 
  of dc-core (general WIP). @link2xt @flub @hpk42 @r10s

- use async-email/async-smtp to handle SMTP connections, might
  fix connection/reconnection issues. @link2xt 

- more tests and refinements for dealing with blobstorage @flub @hpk42 

- use a dedicated build-server for CI testing of core PRs


## 1.0.0-beta.12

- fix python bindings to use core for copying attachments to blobdir
  and fix core to actually do it. @hpk42

## 1.0.0-beta.11

- trigger reconnect more often on imap error states.  Should fix an 
  issue observed when trying to empty a folder.  @hpk42

- un-split qr tests: we fixed qr-securejoin protocol flakiness 
  last weeks. @hpk42

## 1.0.0-beta.10

- fix grpid-determination from in-reply-to and references headers. @hpk42

- only send Autocrypt-gossip headers on encrypted messages. @dignifiedquire

- remove last unsafe code from dc_receive_imf :) @hpk42

- add experimental new dc_chat_get_info_json FFI/API so that desktop devs
  can play with using it. @jikstra

- fix encoding of subjects and attachment-filenames @hpk42
  @dignifiedquire . 

## 1.0.0-beta.9

- historic: we now use the mailparse crate and lettre-email to generate mime
  messages.  This got rid of mmime completely, the C2rust generated port of the libetpan 
  mime-parse -- IOW 22KLocs of cumbersome code removed! see 
  https://github.com/chatmail/core/pull/904#issuecomment-561163330
  many thanks @dignifiedquire for making everybody's life easier 
  and @jonhoo (from rust-imap fame) for suggesting to use the mailparse crate :) 

- lots of improvements and better error handling in many rust modules 
  thanks @link2xt @flub @r10s, @hpk42 and @dignifiedquire 

- @r10s introduced a new device chat which has an initial
  welcome message.  See 
  https://c.delta.chat/classdc__context__t.html#a1a2aad98bd23c1d21ee42374e241f389
  for the main new FFI-API.

- fix moving self-sent messages, thanks @r10s, @flub, @hpk42

- fix flakiness/sometimes-failing verified/join-protocols, 
  thanks @flub, @r10s, @hpk42

- new DC_EVENT_SECUREJOIN_MEMBER_ADDED event 

- many little fixes and rustifications (@link2xt, @flub, @hpk42)


## 1.0.0-beta.8

- now uses async-email/async-imap as the new base 
  which makes imap-idle interruptible and thus fixes
  several issues around the imap thread being in zombie state . 
  thanks @dignifiedquire, @hpk42 and @link2xt. 

- fixes imap-protocol parsing bugs that lead to infinitely
  repeated crashing while trying to receive messages with
  a subject that contained non-utf8. thanks @link2xt

- fixed logic to find encryption subkey -- previously 
  delta chat would use the primary key for encryption
  (which works with RSA but not ECC). thanks @link2xt

- introduce a new device chat where core and UIs can 
  add "device" messages.  Android uses it for an initial
  welcome message. thanks @r10s

- fix time smearing (when two message are virtually send
  in the same second, there would be misbehaviour because
  we didn't persist smeared time). thanks @r10s

- fix double-dotted extensions like .html.zip or .tar.gz  
  to not mangle them when creating blobfiles.  thanks @flub

- fix backup/exports where the wrong sql file would be modified,
  leading to problems when exporting twice.  thanks @hpk42

## 1.0.0-beta.1 

- first beta of the Delta Chat Rust core library. many fixes of crashes
  and other issues compared to 1.0.0-alpha.5.

- Most code is now "rustified" and does not do manual memory allocation anymore. 

- The `DC_EVENT_GET_STRING` event is not used anymore, removing the last
  event where the core requested a return value from the event callback. 

  Please now use `dc_set_stock_translation()` API for core messages
  to be properly localized. 

- Deltachat FFI docs are automatically generated and available here: 
  https://c.delta.chat 

- New events ImapMessageMoved and ImapMessageDeleted
