For full details: https://github.com/scalameta/metals/milestone/75?closed=1

Metals is a language server for Scala that works with VS Code, Vim, Emacs, Zed, Helix and Sublime Text. Metals is developed at the Scala Center and VirtusLab with the help from contributors from the community.

TL;DR​

Support for 2.13.16​

With the new release comes support for Scala 2.13.16. You can read release highlighs in [the Scala 2.13.16 release notes] the Scala 2.13.16 release notes.

Fix for Metals stopped compiling bug​

Previous versions of Metals could sometimes stop compiling the code and fail to report any new errors. This bug was related to a feature, where Metals would pause compilation when focusing out of editor Window. The feature was removed completely, since there was little benefit from it and it was tricky to make it work. If you experienced this bug or a similar one, let us know if this release fixes in for you. Thanks go to tgodzik for debugging this issue.

Error reports improvements​

In one of the previous versions of Metals we added mechanisms to save error reports under .metals/.reports. In case an error was more prominent it could create a large number of duplicate reports.

Now, the reports will be deduplicated properly and the information about created ones will be logged to improve their visibility. As previously, full list of generated reports is visible in the Metals doctor and the .metals/.reports directory.

Inlay hints for worksheets​

Starting from this release, worksheet decorations will be displayed using inlay hints instead of the previous custom solution. This will make worksheet support available for editors that don't implement this extension (e.g. Zed). Thanks tgodzik for implementing this transition.
