 ## What's New
 
+### What's New in Version 2.12.5
+
+You can find all issues related to this release on our [Roadmap](https://github.com/Icinga/icingaweb2/milestone/85?closed=1).
+
+#### PHP 8.4 Support
+
+We're again a little behind schedule, but now we support PHP 8.4! This means that installations on Ubuntu 25.04 and
+Fedora 42+ can now install Icinga Web without worrying about PHP related incompatibilities. Icinga packages will be
+available in the next few days.
+
+#### Good Things Take Time
+
+There's only a single (notable) recent issue that is fixed with this release. All the others are a bit older.
+
+* External URLs set up as dashlets are not *embedded* the same as navigation items [#5346](https://github.com/Icinga/icingaweb2/issues/5346)
+
+But the team sat together a few weeks ago and fixed a bug here and there. And of course, also in Icinga Web!
+
+* Users who are not allowed to change the theme, cannot change the theme mode either [#5385](https://github.com/Icinga/icingaweb2/issues/5385)
+* Filtering for older-than events with relative time does not work [#5263](https://github.com/Icinga/icingaweb2/issues/5263)
+* External logout not working from the navigation dashboard [#5000](https://github.com/Icinga/icingaweb2/issues/5000)
+* Empty values are NULL in CSV exports [#5350](https://github.com/Icinga/icingaweb2/issues/5350)
+
+#### Breaking, Somewhat
+
+This is mainly for developers.
+
+With the support of PHP 8.4, we introduced a new environment variable, `ICINGAWEB_ENVIRONMENT`. Unless set to `dev`,
+Icinga Web will not show nor log deprecation notices anymore.
