 Here are some of the new features we have added to Keyman for Linux 18.0:
-
-- Keyman for Linux now fully works with the Wayland compositor
-  ([#4273](https://github.com/keymanapp/keyman/issues/4273)).
-  Previously the full functionality only worked with the X11 display server.
-- Slightly modified the UI of `km-config`. The new _Options_ tab allows
-  to disable automatic error reporting to keyman.com.
-- Added Mon localization ([#9550](https://github.com/keymanapp/keyman/pull/9550)).
-- It is now possible to specify an arbitrary language tag when installing
-  a keyboard package from the command line ([#8598](https://github.com/keymanapp/keyman/issues/8598)).
-  Previously this only worked for the language tags listed in the
-  keyboard package.
-- Keyman for Linux now supports the upcoming Ubuntu 24.04 Noble LTS in
-  addition to Ubuntu 23.10 Mantic, Ubuntu 22.04 Jammy LTS and
-  Ubuntu 20.04 Focal LTS. Note: This will be last version that supports
-  Ubuntu 20.04 Focal.
-- Keyman Core on Linux supports full normalization for LDML keyboard output
-  ([#10390](https://github.com/keymanapp/keyman/issues/10390)).
-- Renamed the mysterious `libkmnkbp0-0` package to the clearer
-  `libkeymancore1`. Cleanup of the API.
