 # Changelog
 
+## [Unreleased]
+
+### Changes
+- "full message view" not needed because of footers that go to contact status #4151
+- Pick up system's light/dark mode in generated message HTML #4150
+- Support non-persistent configuration with DELTACHAT_* env
+- Print deltachat-repl errors with causes. #4166
+- Increase MSRV to 1.64. #4167
+- Core takes care of stopping and re-starting IO itself where needed,
+  e.g. during backup creation.  It is no longer needed to call
+  dc_stop_io().  dc_start_io() can now be called at any time without
+  harm. #4138
+- More accurate maybe_add_bcc_self device message text #4175
+
+### 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
+- Delete expired messages using multiple SQL requests. #4158
+- Do not emit "Failed to run incremental vacuum" warnings on success. #4160
+- Ability to send backup over network and QR code to setup second device #4007
+- Disable buffering during STARTTLS setup. #4190
+
+## [1.111.0] - 2023-03-05
+
+### Changes
+- Make smeared timestamp generation non-async. #4075
+- Set minimum TLS version to 1.2. #4096
+- Run `cargo-deny` in CI. #4101
+- Check provider database with CI. #4099 
+- Switch to DEFERRED transactions #4100
+
+### Fixes
+- Do not block async task executor while decrypting the messages. #4079
+- Housekeeping: delete the blobs backup dir #4123
+
+### API-Changes
+- jsonrpc: add more advanced API to send a message. #4097
+- jsonrpc: add get webxdc blob API `getWebxdcBlob` #4070
+
+
+## 1.110.0
+
+### Changes
+- use transaction in `Contact::add_or_lookup()` #4059
+- Organize the connection pool as a stack rather than a queue to ensure that
+  connection page cache is reused more often.
+  This speeds up tests by 28%, real usage will have lower speedup. #4065
+- Use transaction in `update_blocked_mailinglist_contacts`. #4058
+- Remove `Sql.get_conn()` interface in favor of `.call()` and `.transaction()`. #4055
+- Updated provider database.
+- Disable DKIM-Checks again #4076
+- Switch from "X.Y.Z" and "py-X.Y.Z" to "vX.Y.Z" tags. #4089
+- mimeparser: handle headers from the signed part of unencrypted signed message #4013
+
+### Fixes
+- Start SQL transactions with IMMEDIATE behaviour rather than default DEFERRED one. #4063
+- 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
+
+### API-Changes
+
+
+## 1.109.0
+
+### Changes
+- deltachat-rpc-client: use `dataclass` for `Account`, `Chat`, `Contact` and `Message` #4042
+
+### Fixes
+- deltachat-rpc-server: do not block stdin while processing the request. #4041
+  deltachat-rpc-server now reads the next request as soon as previous request handler is spawned.
+- Enable `auto_vacuum` on all SQL connections. #2955
+- Replace `r2d2` connection pool with an own implementation. #4050 #4053 #4043 #4061
+  This change improves reliability
+  by closing all database connections immediately when the context is closed.
+
+### API-Changes
+
+- Remove `MimeMessage::from_bytes()` public interface. #4033
+- BREAKING Types: jsonrpc: `get_messages` now returns a map with `MessageLoadResult` instead of failing completely if one of the requested messages could not be loaded. #4038
+- Add `dc_msg_set_subject()`. C-FFI #4057
+- Mark python bindings as supporting typing according to PEP 561 #4045
+
+

 - With this approach, it's easy 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.

 ### Alternatives and old discussions/plans:
 
 - Change the contact instead of rewriting the group member lists. This seems to call for more trouble since we will end up with multiple contacts having the same email address.
 
-- If needed, we could add a header a) indicating that the sender did an address transition or b) listing all the secondary (old) addresses.
