What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

###### Important changes

⚠️ **HedgeDoc 1.12.0 and onwards will require Node 20.17 or later in order to run.**
Since Node 18 security support was stopped over one year ago, we don't maintain backwards-compatability for that anymore.

Some syntax highlighting languages have been removed and/or changed. You can find more information in
[the highlight.js docs](https://highlightjs.readthedocs.io/en/latest/upgrade-11.html#built-in-set-of-common-languages).

###### Enhancements

- Automatically skip the login modal if no form-based login and exactly one external login provider is configured

###### Bugfixes

- All links will be opened in new tabs instead of the same tab as the note. This was changed when the external link warning was implemented and now the old behavior is restored
- Fixed multiple bugs in the realtime connection handling that could lead to data-loss of users with a flaky connection
