 - `neovimUtils.makeNeovimConfig` now uses `customLuaRC` parameter instead of accepting `luaRcContent`. The old usage is deprecated but still works with a warning.
 
+- `python3Packages.pyocr` no longer supports `cuneiform` on Linux by default. It is still possible to enable it using `withCuneiformSupport` override.
+
 - `telegram-desktop` packages now uses `Telegram` for its binary. The previous name was `telegram-desktop`. This is due to [an upstream decision](https://github.com/telegramdesktop/tdesktop/commit/56ff5808a3d766f892bc3c3305afb106b629ef6f) to make the name consistent with other platforms.
 
 - `hsd` has been upgraded to version 8. See [their changelog](https://github.com/handshake-org/hsd/blob/v8.0.0/docs/release-notes/release-notes-8.x.md) for important instructions before upgrading.
