refactor: remove Secure-Join-Fingerprint header

refactor: rename notify_peer_verified() into set_peer_verified()

-
-## [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/deltachat/deltachat-core-rust/pull/5211)).
- CFFI: add `dc_accounts_background_fetch` and event `DC_EVENT_ACCOUNTS_BACKGROUND_FETCH_DONE`.
- JSON-RPC: add `accounts_background_fetch`.
-
-### Features / Changes
-
- `Qr::check_qr()`: Accept i.delta.chat invite links ([#5217](https://github.com/deltachat/deltachat-core-rust/pull/5217)).
- Add support for IMAP METADATA, fetching `/shared/comment` and `/shared/admin` and displaying it in account info.
-
-### Fixes
-
- Add tolerance for macOS and iOS changing `#` to `%23`.
- Do not drop unknown report attachments, such as TLS reports.
- Treat only "Auto-Submitted: auto-generated" messages as bot-sent ([#5213](https://github.com/deltachat/deltachat-core-rust/pull/5213)).

- Fix iOS build issue.
-
-### CI

-
-### Tests
-
- `test_import_export_online_all`: Send the message to the existing address to avoid errors ([#5220](https://github.com/deltachat/deltachat-core-rust/pull/5220)).
-
-## [1.133.2] - 2024-01-24
-
-### Fixes
-
- Downgrade OpenSSL from 3.2.0 to 3.1.4 ([#5206](https://github.com/deltachat/deltachat-core-rust/issues/5206))
- No new chats for MDNs with alias ([#5196](https://github.com/deltachat/deltachat-core-rust/issues/5196)) ([#5199](https://github.com/deltachat/deltachat-core-rust/pull/5199)).
-
-## [1.133.1] - 2024-01-21
-
-### API-Changes
-
- Add `is_bot` to cffi and jsonrpc ([#5197](https://github.com/deltachat/deltachat-core-rust/pull/5197)).
-
-### Features / Changes
-
- Add system message when provider does not allow unencrypted messages ([#5195](https://github.com/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/pull/5194)).
- Use Quoted-Printable MIME encoding for the text part ([#3986](https://github.com/deltachat/deltachat-core-rust/pull/3986)).
-
-### Tests
-
- python: Add `get_protected_chat` to testplugin.py.
-
-## [1.133.0] - 2024-01-14
-
-### Features / Changes
-
- Securejoin protocol implementation refinements
-  - Track forward and backward verification separately ([#5089](https://github.com/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/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 elments based on the configuration key which is a part of the event.
- Sync contact creation/rename across devices ([#5163](https://github.com/deltachat/deltachat-core-rust/pull/5163)).
- Encrypt MDNs ([#5175](https://github.com/deltachat/deltachat-core-rust/pull/5175)).
- Only try to configure non-strict TLS checks if explicitly set ([#5181](https://github.com/deltachat/deltachat-core-rust/pull/5181)).
-
-### Build system
-
- Use released version of iroh 0.4.2 for "setup second device" feature.
-
-### CI
-
- Update to Rust 1.75.0.
- Downgrade `chai` from 4.4.0 to 4.3.10.
-
-### Documentation
-
- Add a link <https://www.ietf.org/archive/id/draft-bucksch-autoconfig-00.html> to autoconfig RFC draft.
- 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/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/pull/5119)).
- Emit events more reliably when starting and stopping I/O ([#5101](https://github.com/deltachat/deltachat-core-rust/pull/5101)).
- Fix timestamp of chat protection info message for correct message ordering after restoring a backup ([#5088](https://github.com/deltachat/deltachat-core-rust/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
-
- Test joining non-protected group.
- Test that read receipts don't degrade encryption.
- Test that changing default private key breaks backward verification.
- Test recovery from lost vc-contact-confirm.
- Use `wait_for_incoming_msg_event()` more.

link2xt	c352a4478f	refactor: rename notify_peer_verified() into set_peer_verified() It was named notify_peer_verified() because it added info message, but this is no longer true since https://github.com/deltachat/deltachat-core-rust/pull/4998 (commit `c6ea4e389a`) is merged.	2024-01-09 03:09:30 +00:00
link2xt	acb4830a54	refactor: do not emit ChatModified event in notify_peer_verified() The chat is not modified at least since `c6ea4e389a` (PR https://github.com/deltachat/deltachat-core-rust/pull/4998), even the info message is not posted there.	2024-01-09 03:08:04 +00:00
link2xt	8361541de1	feat: mark 1:1 chat as verified for Bob early Mark 1:1 chat as verified as soon as Alice is forward-verified so Bob can already start sending Chat-Verified headers. This way Alice and Bob can scan each other's QR codes and even if all Secure-Join headers are dropped from the network, still get forward verifications via QR-code scans and backward verifications via Chat-Verified messages in 1:1 chat.	2024-01-09 02:24:14 +00:00
