 # Changelog
 
-## Unreleased
+## [Unreleased]
 
-## Changes
+### 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
+### 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
 
-## API-Changes
+## [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
+
+
+## 1.108.0
+
+### Changes
+- Use read/write timeouts instead of per-command timeouts for SMTP #3985
+- Cache DNS results for SMTP connections #3985
+- Prefer TLS over STARTTLS during autoconfiguration #4021
+- Use SOCKS5 configuration for HTTP requests #4017
+- Show non-deltachat emails by default for new installations #4019
+- Re-enabled SMTP pipelining after disabling it in #4006
+
+### Fixes
+- Fix Securejoin for multiple devices on a joining side #3982
+- python: handle NULL value returned from `dc_get_msg()` #4020
+  Account.`get_message_by_id` may return `None` in this case.
+
+### API-Changes
+- Remove bitflags from `get_chat_msgs()` interface #4022
+  C interface is not changed.
+  Rust and JSON-RPC API have `flags` integer argument
+  replaced with two boolean flags `info_only` and `add_daymarker`.
+- jsonrpc: add API to check if the message is sent by a bot #3877

+# Delta Chat RPC server
+
+This program provides a [JSON-RPC 2.0](https://www.jsonrpc.org/specification) interface to DeltaChat
+over standard I/O.
+
+## Install
+
+To download binary pre-builds check the [releases page](https://github.com/deltachat/deltachat-core-rust/releases).
+Rename the downloaded binary to `deltachat-rpc-server` and add it to your `PATH`.
+
+To install from source run:
+
+```sh
+cargo install --git https://github.com/deltachat/deltachat-core-rust/ deltachat-rpc-server
+```
+
+The `deltachat-rpc-server` executable will be installed into `$HOME/.cargo/bin` that should be available
+in your `PATH`.
+
+## Usage
+
+To use just run `deltachat-rpc-server` command. The accounts folder will be created in the current
+working directory unless `DC_ACCOUNTS_PATH` is set:
+
+```sh
+export DC_ACCOUNTS_PATH=$HOME/delta/
+deltachat-rpc-server
+```
+
+The common use case for this program is to create bindings to use Delta Chat core from programming
+languages other than Rust, for example:
+
+1. Python: https://github.com/deltachat/deltachat-core-rust/tree/master/deltachat-rpc-client/
+2. Go: https://github.com/deltachat/deltachat-rpc-client-go/

 - 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.  For now, there is no big enough benefit to warrant introducing another header and its processing on the receiver side (including all the neccessary checks and handling of error cases). Instead, we only check for the `Chat-Version` header to prevent accidental transitions when an MUA user sends a message from another email address with the same key.
