 ## What's New
 
-### What's New in Version 2.12.6
-
-You can find all issues related to this release on our [Roadmap](https://github.com/Icinga/icingaweb2/milestone/86?closed=1).
-
-#### It's Like Fine Wine
-
-Icinga Web 2.12 is now two years old. But like fine wine, it gets better with age. Each fix and improvement included
-this time enhances your experience with Icinga Web. Even if just a little bit. Maybe a small annoyance is gone now, or
-something you didn't even notice was broken is fixed.
-
-But let's get to it, a small selection of fixes and improvements:
-
-* Search box shows many magnifying glasses for some community themes #5395
-* Authentication hooks are not called with external backends #5415
-* Improve Minimal layout #5386
-
-### 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.
-
-### What's New in Version 2.12.4
-
-This is a hotfix release which fixes the following issue:
-
-Database login broken after upgrade [#5343](https://github.com/Icinga/icingaweb2/issues/5343)
-
-### What's New in Version 2.12.3
-
-**Notice:** This is a security release. It is recommended to upgrade _immediately_.
-
-You can find all issues related to this release on our [Roadmap](https://github.com/Icinga/icingaweb2/milestone/83?closed=1).
-
-#### Vulnerabilities, Closed
-
-Cross site scripting is one of the worst attacks on web based platforms. Especially, if carrying it out is as easy as
-the first two mentioned here. You might recognize the open redirect on the login. You are correct, we attempted to fix
-it already with v2.11.3 but underestimated PHP's quirks. The last is difficult to exploit, hence the lowest severity
-of all, but don't be fooled by that!
-
-All four of them are backported to v2.11.5.
-
-* XSS in embedded content [CVE-2025-27405](https://github.com/Icinga/icingaweb2/security/advisories/GHSA-3x37-fjc3-ch8w)
-* DOM-based XSS [CVE-2025-27404](https://github.com/Icinga/icingaweb2/security/advisories/GHSA-c6pg-h955-wf66)
-* Open redirect on login page [CVE-2025-30164](https://github.com/Icinga/icingaweb2/security/advisories/GHSA-8r73-6686-wv8q)
-* Reflected XSS [CVE-2025-27609](https://github.com/Icinga/icingaweb2/security/advisories/GHSA-5cjw-fwjc-8j38)
-
-Big thanks to all finders / reporters! :+1:
-
-#### Bugs, Exterminated
-
-Did you know, that we started [Icinga Notifications](https://icinga.com/docs/icinga-notifications/latest/) with support
-for PostgreSQL first? Reason for that is, we wanted to make sure we are fully compatible with it right away. To ensure
-things like logging in with a PostgreSQL authentication/group backend is case-insensitive, like it was always the case
-for MySQL. Now it **really** is case-insensitive! There are also two issues fixed, which many of you will probably have
-noticed since v2.12.2, sorry that it took so long :)
-
-* Login against Postgres DB is case-sensitive [#5223](https://github.com/Icinga/icingaweb2/issues/5223)
-* Role list has no functioning quick search [#5300](https://github.com/Icinga/icingaweb2/issues/5300)
-* After clicking on Check now, the page does not refresh itself [#5293](https://github.com/Icinga/icingaweb2/issues/5293)
-* Service States display wrong since update to 2.12.2 [#5290](https://github.com/Icinga/icingaweb2/issues/5290)
