+# (2026-05-21) Version 1.19.2
+
+- (**Internal Improvement**) Update [async-openai](https://crates.io/crates/async-openai) to 0.40.0.
+
+- (**Internal Improvement**) Dependency updates.
+
+
+# (2026-05-09) Version 1.19.1
+
+- (**Internal Improvement**) Update [async-openai](https://crates.io/crates/async-openai) to 0.38.0.
+
+- (**Internal Improvement**) Dependency updates.
+
+
+# (2026-05-09) Version 1.19.0
+
+- (**Internal Improvement**) Update [matrix-sdk](https://crates.io/crates/matrix-sdk) from 0.16 to 0.17 and [mxlink](https://crates.io/crates/mxlink) to 1.14.0. matrix-sdk 0.17 dropped its `native-tls` feature and now uses [rustls](https://github.com/rustls/rustls) exclusively as its TLS backend.
+
+- (**Internal Improvement**) Bump the pinned Rust toolchain from 1.93.0 to 1.95.0 (in `rust-toolchain.toml` and the Docker build images).
+
+- (**Internal Improvement**) Dependency updates.
+
+
+# (2026-04-11) Version 1.18.0
+
+- (**Bugfix**) Fix the bot not sending a welcome message when joining a room on homeservers (like [Continuwuity](https://continuwuity.org/)) that place the join membership event in the sync response's `state` block rather than the `timeline` block, via [mxlink](https://crates.io/crates/mxlink) 1.13.1
+
+- (**Improvement**) Update [tiktoken-rs](https://crates.io/crates/tiktoken-rs) to 0.11, adding tokenization support for newer GPT models (gpt-5.x, codex, etc.) and fixing context sizes for o1-mini/chatgpt-4o/gpt-4.5
+
+- (**Internal Improvement**) Dependency updates
+
+
 # (2026-03-25) Version 1.17.0
 
 - (**Feature**) Add `text-generation sender-context-mode` for attaching sender metadata to conversation messages. See the [💬 Text Generation](./docs/configuration/text-generation.md#-sender-context-mode) documentation for details. Thanks to [kschwank](https://github.com/kschwank) for the contribution in [#104](https://github.com/etkecc/baibot/pull/104)!
