chore(release): prepare for 1.125.0

If there's a temporary SMTP error, pretend there are no more MDNs to send in send_mdn(). It's
unlikely that other MDNs could be sent successfully in case of connectivity problems. This approach
is simpler and perhaps even better than adding a progressive backoff between MDN sending retries --
MDNs just will be resent after a reconnection, which makes some sense.

 # Changelog
 
-## Unreleased
+## [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: fix bug in client.py and add missing `EventType.MSG_DELETED`
+- `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
+

+
+### 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).
+
+## [1.120.0] - 2023-08-28
+
+### API-Changes

+### Fixes
+
+- Update async-imap to 0.9.1 to fix memory leak.
+- Delete messages from SMTP queue only on user demand ([#4579](https://github.com/deltachat/deltachat-core-rust/pull/4579)).
+- Do not send images without transparency as stickers ([#4611](https://github.com/deltachat/deltachat-core-rust/pull/4611)).

-### 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:#}.");
-```
