i3/RELEASE-NOTES-4.25

 │ Release notes for i3 v4.25   │
 └──────────────────────────────┘

This is i3 v4.25. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.

Most changes in this release cycle have been “behind the scenes”,
without an observable effect for users. For example, we switched
to clang-format-20, fixed a number of (benign) memory issues,
fixed a few flaky tests and maintained our GitHub Actions setup,
e.g. for the shutdown of baltocdn (our old host for nightly builds).

We also investigated shipping an i3.service systemd user unit,
but could not make that work without breaking existing setups.
If distribution maintainers (or anyone) has advice, please share
(after reading up!) over in https://github.com/i3/i3/issues/5186

  • Set _NET_FRAME_EXTENTS according to the actual decoration size.
    This improves compatibility with picom and other software.

    advanced for_window usages (e.g. multiple criteria).
