2025.4.3 “just a few bugfixes, honest!”

This should have been a small release, to fix some bugs in 2025.4.2, but we added a bunch of features as well.

The most visible changes are support for the fediverse:creator link attributions, and better support for quotes in non-Misskey software.

Everything should feel quite a bit faster, thanks to many optimisations in the backend.

A couple of important notes:

we’ve improved the process of migrating frontend settings from pre-2025.4 versions; if your users had a broken migration, they can try re-importing via ⚙️settings → …other → “🗘migrate old client settings”, but we suggest backing up their current preferences first
it’s possible to let non-logged-in users use the translation function, but to minimise risks, the default policy now disables translation, you may want to create a conditional role matching all local users to re-enable it for them
we’ve added many new indexes to the database, we recommend running a VACUUM (ANALYSE, VERBOSE) after the migrations have completed
if you do not use Docker, to avoid potential crashes when rendering some SVG images, you should make sure that your system has librsvg and some fonts (on Debian-style systems, that’s librsvg2-2 and fonts-noto)
