 # Changelog

-## [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)).
-
-### Features / Changes
-
- Introduce keyupdate messages informing contacts about relay changes.
- Remove `Final-Recipient` from MDNs (and keyupdates).
- Carry all published relay addresses in securejoin links ([#8591](https://github.com/chatmail/core/pull/8591)).
- Use display name for contacts in encryption info ([#8609](https://github.com/chatmail/core/pull/8609)).
- Do not create device messages for IMAP authentication errors.
- Delete avatars referred to by parameters of special contacts.
- Import `Autocrypt-Gossip` keys without checking the addresses.
- Ignore `Chat-Disposition-Notification-To` value.
- Increase `sys.msgsize_max_recommended` to match chatmail relay message size limit.
-
-### Fixes
-
- Do not try to load profile image from param for self.
- Send legacy securejoin key requests as `multipart/mixed` so they are not rejected by chatmail relays.
- rpc: avoid hang when requests race a dying rpc-server.
- Take `timestamp_rcvd` into account in `estimate_deletion_cnt`.
- Reliably complete configuration with progress=1000 or progress=0.
- Make `create_send_msg_jobs` actually return row IDs.
- Don't notify of missed call from blocked user.
- Trash MDNs that reference no message early.
- Return no relay address for key-contacts without an address.
- Do not emit events in `set_profile_image()` if contact avatar is unchanged.
- Remove `Original-Recipient` field from MDNs.
- ffi: support custom allocators in event string getters.
- Start checking column documentation in CI and add comment for `transports.add_timestamp`.
- Sanitize `version_string` we got from the wire ([#8582](https://github.com/chatmail/core/pull/8582))
- RUSTSEC-2026-0258 ([#8603](https://github.com/chatmail/core/pull/8603)).
-
-### Build system
-
- Use `--locked` in `scripts/clippy.sh`.
- Produce correct wheel metadata.
-
-### Documentation
-
- Always suggest using `--locked` with "cargo install".
- JSON-RPC: clarify when `reactions` is `None`.
- Fix async-imap and async-smtp URLs in README.md ([#8637](https://github.com/chatmail/core/pull/8637)).
- Update the timeout value in `DC_EVENT_CALL_ENDED` description.
-
-### Refactor
-
- Don't store email address in location KML. ([#8615](https://github.com/chatmail/core/pull/8615)).
- Turn `DC_CHAT_ID_*` into `ChatId::*` associated constants.
- Turn `DC_MSG_ID_*` into `MsgId::*` associated constants.
- Don't include email addresses in export filenames ([#8626](https://github.com/chatmail/core/pull/8626)).
- Make `create_send_msg_jobs()` private.
- Rename `automatic_relay_management` to autorelay.
- Extract shared pieces for non-chat messages.
- Remove unused functions from the tools module.
- Remove the code to set own avatar in `set_profile_image()`.
- Move pgp tests to submodule.
- Split `flake.nix` into multiple files.
- Use `&[..]` instead of `&Vec<..>`.
-
-### Tests
-
- [**breaking**] rename rpc fixtures to disambiguate from ffi fixtures.
- Test `dc_send_msg_sync()`.
- Print which error/warning was expected if it does not arrive.
-
-### CI
-
- Update Rust to 1.98.1.
-
-### Miscellaneous Tasks

- Add script to show the sizes of futures (async Rust) ([#8536](https://github.com/chatmail/core/pull/8536)).

-
-### API-Changes

-### Documentation
-

-### Performance
-
- Enable `clippy::large_futures` lint.
- Stop sending locations concurrently.
- Set location for all accounts in parallel.
- `is_self_addr()`: Employ the config cache to optimize for `ConfiguredAddr` passed.
-
-### Refactor
-
- Get rid of `MessageState::{OutPreparing,OutMdnRcvd}` in the db.
- Make HTML parser non-async.
- Replace `HashSet` with `BTreeSet`.
- Rename `EnteredLoginParam::load()` and save() to `load_legacy()` and `save_legacy()`.
- Remove unnecessary async block in `dc_set_location`.
- Remove unused Authentication-Results parsing ([#8172](https://github.com/chatmail/core/pull/8172)).
- Remove mostly-unused function `get_secondary_self_addrs()` ([#8173](https://github.com/chatmail/core/pull/8173)).
- Use `self_fingerprint()` where it makes sense ([#8174](https://github.com/chatmail/core/pull/8174)).
- Split `is_sending_locations_to_chat()` into two functions.
- Use regular functions rather than FromStr impls ([#8178](https://github.com/chatmail/core/pull/8178)).
- Make `Fingerprint` not implement `Display` ([#8177](https://github.com/chatmail/core/pull/8177)).
- Don't temporarily extend `signatures` for signed-only messages.
- Use some more let..else.
- Remove outdated comment.
- Un-nest `handle_edit_delete`.
- Drop support for replacing partial download stubs.
-
-### Tests
-
- Use `displayname` instead of `show_emails` for config cache test.
- Remove unused test data related to Authentication-Result parsing ([#8175](https://github.com/chatmail/core/pull/8175)).
- `EventTracker::get_matching_opt`: Return the first matching event, not last.
- Set email addresses explicitly for the test accounts.
- Use encrypted messages in more tests.
- Add `TestContext.allow_unencrypted()`.
- Online test for legacy Secure-Join key request.

-## [2.49.0] - 2026-04-13
-
-### Features / Changes
-
- Flipped Exif orientations ([#8057](https://github.com/chatmail/core/pull/8057)).
-
-### Fixes
-
- Determine whether a message is an own message by looking at signature. multiple devices can temporarly have different sets of self addresses, and still need to properly recognize incoming versus outgoing messages. Disclaimer: some LLM tooling was initially involved but i went over everything by hand, and also addressed review comments..
- Mark a message as delivered only after it has been fully sent out ([#8062](https://github.com/chatmail/core/pull/8062)).
- Do not create 1:1 chat on second device when scanning a QR code.
- Do not URL-encode proxy hostnames.
- Assign webxdc updates from post-message to webxdc instance.
- Let search also return hidden contacts if search value is an email address.
- Add missing `extern "C"` to `dc_array_is_independent`.
- Make start messages stick to the top of the chat.
- For bots, wait with emitting IncomingMsg until the Post-Msg arrived ([#8104](https://github.com/chatmail/core/pull/8104)).
- Trash message about group name change from non-member.
-
-### API-Changes
-
- [**breaking**] remove `dc_msg_force_plaintext`.
- @deltachat/stdio-rpc-server: also export a class.
-
-### CI
-
- Make sure `-dev` version suffix is not forgotten after release.
-
-### Documentation
-
- Document that events are broadcasted to all event emitters.
- Fix broken link for i-d "Common PGP/MIME Message Mangling".
-
-### Refactor
-
- ignore ForcePlaintext in saved messages chat.
- @deltachat/stdio-rpc-server: make `getRPCServerPath` and `startDeltaChat` synchronous.
- @deltachat/stdio-rpc-server: remove `await` from README example.
- less nested `remove_contact_from_chat`.
-
-### Tests
-
- Add test for `tweak_sort_timestamp()`.
- Test that messages are only marked as delivered after being fully sent out ([#8077](https://github.com/chatmail/core/pull/8077)).
- Fix flaky `test_no_old_msg_is_fresh`: Wait for incoming message before sending outgoing one.
- Use TestContextManager in `test_keep_member_list_if_possibly_nomember`.
-
-### Miscellaneous Tasks
-
- cargo: bump chrono from 0.4.43 to 0.4.44.
- cargo: bump tracing-subscriber from 0.3.22 to 0.3.23.
- cargo: bump tempfile from 3.26.0 to 3.27.0.
- cargo: bump pin-project from 1.1.10 to 1.1.11.
- cargo: bump tokio from 1.49.0 to 1.50.0.
- cargo: bump libc from 0.2.182 to 0.2.183.
- cargo: bump quote from 1.0.44 to 1.0.45.
- cargo: bump image from 0.25.9 to 0.25.10.
- cargo: bump proptest from 1.10.0 to 1.11.0.
- deps: bump dependabot/fetch-metadata from 2.4.0 to 3.0.0.
- bump version to 2.49.0-dev.
-
-## [2.48.0] - 2026-03-30
-
-### Fixes
-
- Fix reordering problems in multi-relay setups by not sorting received messages below the last seen one.
- Always sort "Messages are end-to-end encrypted" notice to the beginning.
- Make Message-ID of pre-messages stable across resends ([#8007](https://github.com/chatmail/core/pull/8007)).
- Delete `imap_markseen` entries not corresponding to any `imap` rows.
- Cleanup `imap` and `imap_sync` records without transport in housekeeping.
- When receiving MDN, mark all preceding messages as noticed, even having same timestamp ([#7928](https://github.com/chatmail/core/pull/7928)).
- Remove migration 108 preventing upgrades from core 1.86.0 to the latest version.
-
-### Features / Changes
-
- Improve IMAP loop logs.
- Add decryption error to the device message about outgoing message decryption failure.
- Log received message sort timestamp.
-
-### Performance
-
- Move sorting outside of SQL query in `store_seen_flags_on_imap`.
-
-### API-Changes
-
- Add JSON-RPC API `markfresh_chat()`.
- ffi: Correctly declare `dc_event_channel_new()` as having no params ([#7831](https://github.com/chatmail/core/pull/7831)).
-
-### Refactor
-
- Remove `wal_checkpoint_mutex`, lock `write_mutex` before getting sql connection instead.
- Replace async `RwLock` with sync `RwLock` for stock strings.
- Cleanup remaining Autocrypt Setup Message processing in `mimeparser`.
- SecureJoin: do not check for self address in forwarding protection.
- Fix clippy warnings.
-
-### CI
-
- Update {c,py}.delta.chat website deployments.
- Use environments for {rs,cffi,js.jsonrpc}.delta.chat deployments.
- Fix https://docs.zizmor.sh/audits/#bot-conditions.
-
-### Documentation
-
- Add SQL performance tips to STYLE.md.
-
-### Tests
-
- Remove `test_old_message_5`.
- Do not rely on loading newest chat in `load_imf_email()`.
- Use `load_imf_email()` more.
- The message is sorted correctly in the chat even if it arrives late.
-
-### Miscellaneous Tasks
-
- cargo: update rustls-webpki to 0.103.10.
