-- Build `deltachat-rpc-server` wheels for macOS and Windows.
-
-### Refactor
-
-- Remove job queue.
-
-### Miscellaneous Tasks
-
-- cargo: Update `ahash` to make `cargo-deny` happy.
-
-## [1.126.0] - 2023-10-22
-
-### API-Changes
-
-- Allow to filter by unread in `chatlist:try_load` ([#4824](https://github.com/deltachat/deltachat-core-rust/pull/4824)).
-- Add `misc_send_draft()` to JSON-RPC API ([#4839](https://github.com/deltachat/deltachat-core-rust/pull/4839)).
-
-### Features / Changes
-
-- [**breaking**] Make broadcast lists create their own chat ([#4644](https://github.com/deltachat/deltachat-core-rust/pull/4644)).
-  - This means that UIs need to ask for the name when creating a broadcast list, similar to <https://github.com/deltachat/deltachat-android/pull/2653>.
-- Add self-address to backup filename ([#4820](https://github.com/deltachat/deltachat-core-rust/pull/4820))
-
-### CI
-
-- Build Python wheels for deltachat-rpc-server.
-
-### Build system
-
-- Strip release binaries.
-- Workaround OpenSSL crate expecting libatomic to be available.
-
-### Fixes
-
-- Set `soft_heap_limit` on SQLite database.
-- imap: Fallback to `STATUS` if `SELECT` did not return UIDNEXT.
-
-## [1.125.0] - 2023-10-14
-
-### API-Changes
-
-- [**breaking**] deltachat-rpc-client: Replace `asyncio` with threads.
-- Validate boolean values passed to `set_config`. Attempts to set values other than `0` and `1` will result in an error.
-
-### CI
-
-- Reduce required Python version for deltachat-rpc-client from 3.8 to 3.7.
-
-### Features / Changes
-
-- Add developer option to disable IDLE.
-
-### 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/deltachat/deltachat-core-rust/pull/4700)).
-- Assign encrypted partially downloaded group messages to 1:1 chat ([#4757](https://github.com/deltachat/deltachat-core-rust/pull/4757)).
-- Return all contacts from `Contact::get_all` for bots ([#4811](https://github.com/deltachat/deltachat-core-rust/pull/4811)).
-- Set connectivity status to "connected" during fake idle.
-- Return verifier contacts regardless of their origin.
-- Don't try to send more MDNs if there's a temporary SMTP error ([#4534](https://github.com/deltachat/deltachat-core-rust/pull/4534)).
-
-### Refactor
-
-- deltachat-rpc-client: Close stdin instead of sending `SIGTERM`.
-- deltachat-rpc-client: Remove print() calls. Standard `logging` package is for logging instead.
-
-### Tests
-
-- deltachat-rpc-client: Enable logs in pytest.
-
-## [1.124.1] - 2023-10-05
-
-### Fixes
-
-- Remove footer from reactions on the receiver side ([#4780](https://github.com/deltachat/deltachat-core-rust/pull/4780)).
-
-### CI
-
-- Pin `urllib3` version to `<2`. ([#4788](https://github.com/deltachat/deltachat-core-rust/issues/4788))
-
-## [1.124.0] - 2023-10-04
-
-### 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.
-- Require valid email addresses in `dc_provider_new_from_email[_with_dns]`.
-- Do not trash messages with attachments and no text when `location.kml` is attached ([#4749](https://github.com/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/issues/4756)).
-- Cap percentage in connectivity layout to 100% ([#4765](https://github.com/deltachat/deltachat-core-rust/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/deltachat/deltachat-core-rust/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
-
-- Remove extra members from the local list in sake of group membership consistency ([#3782](https://github.com/deltachat/deltachat-core-rust/issues/3782)).
-- deltachat-rpc-client: Log exceptions when long-running tasks die.
-
-### Build
-
-- Build wheels for Python 3.12 and PyPy 3.10.
-
-## [1.123.0] - 2023-09-22
-
-### API-Changes
-
-- Make it possible to import secret key from a file with `DC_IMEX_IMPORT_SELF_KEYS`.
-- [**breaking**] Make `dc_jsonrpc_blocking_call` accept JSON-RPC request.
-
-### Fixes
-
-- `lookup_chat_by_reply()`: Skip not fully downloaded and undecipherable messages ([#4676](https://github.com/deltachat/deltachat-core-rust/pull/4676)).
-- `lookup_chat_by_reply()`: Skip undecipherable parent messages created by older versions ([#4676](https://github.com/deltachat/deltachat-core-rust/pull/4676)).
-- imex: Use "default" in the filename of the default key.
-
-### Miscellaneous Tasks
-
-- Update OpenSSL from 3.1.2 to 3.1.3.
-
-## [1.122.0] - 2023-09-12
-
-### API-Changes
-
-- jsonrpc: Return only chat IDs for similar chats.
-
-### Fixes
-
-- Reopen all connections on database passpharse change.
-- Do not block new group chats if 1:1 chat is blocked.
-- Improve group membership consistency algorithm ([#3782](https://github.com/deltachat/deltachat-core-rust/pull/3782))([#4624](https://github.com/deltachat/deltachat-core-rust/pull/4624)).
-- Forbid membership changes from possible non-members ([#3782](https://github.com/deltachat/deltachat-core-rust/pull/3782)).
-- `ChatId::parent_query()`: Don't filter out OutPending and OutFailed messages.
-
-### Build system
-
-- Update to OpenSSL 3.0.
-- Bump webpki from 0.22.0 to 0.22.1.
-- python: Add link to Mastodon into projects.urls.
-
-### Features / Changes
-
-- Add RSA-4096 key generation support.
-
-### Refactor
-
-- pgp: Add constants for encryption algorithm and hash.
-
-## [1.121.0] - 2023-09-06
-
-### API-Changes
-
-- Add `dc_context_change_passphrase()`.
-- Add `Message.set_file_from_bytes()` API.
-- Add experimental API to get similar chats.
-
-### Build system
-
-- Build node packages on Ubuntu 18.04 instead of Debian 10.
-  This reduces the requirement for glibc version from 2.28 to 2.27.
-
-### Fixes
-
-- Allow membership changes by a MUA if we're not in the group ([#4624](https://github.com/deltachat/deltachat-core-rust/pull/4624)).
-- Save mime headers for messages not signed with a known key ([#4557](https://github.com/deltachat/deltachat-core-rust/pull/4557)).
-- Return from `dc_get_chatlist(DC_GCL_FOR_FORWARDING)` only chats where we can send ([#4616](https://github.com/deltachat/deltachat-core-rust/pull/4616)).
-- Do not allow dots at the end of email addresses.
-- deltachat-rpc-client: Remove `aiodns` optional dependency from required dependencies.
-  `aiodns` depends on `pycares` which [fails to install in Termux](https://github.com/saghul/aiodns/issues/98).

+### Errors
+
+Delta Chat core mostly uses [`anyhow`](https://docs.rs/anyhow/) errors.
+When using [`Context`](https://docs.rs/anyhow/latest/anyhow/trait.Context.html),
+capitalize it but do not add a full stop as the contexts will be separated by `:`.
+For example:
+```
+.with_context(|| format!("Unable to trash message {msg_id}"))
+```
+
+### Logging
+
+For logging, use `info!`, `warn!` and `error!` macros.
+Log messages should be capitalized and have a full stop in the end. For example:
+```
+info!(context, "Ignoring addition of {added_addr:?} to {chat_id}.");
+```
+
+Format anyhow errors with `{:#}` to print all the contexts like this:
+```
+error!(context, "Failed to set selfavatar timestamp: {err:#}.");
+```
+

 - With this approach, it's easier to switch to a model where the info about the transition is encoded in the PGP key. Since the key is gossiped, the information about the transition will spread virally.
 - (Also, less important: Slightly faster transition: If you send a message to e.g. "Delta Chat Dev", all members of the "sub-group" "delta android" will know of your transition.)
-- It's easier to implement (if too many problems turn up, we can still switch to another approach and didn't waste that much development time.)
