Overall a good release with many internal improvements to the code. But there are a few issues that may cause early adopters some grief. Patches for most of them exist and I'm sure an updated release will include the fixes soon.

Note hat PHP 7.4 or higher is now required. As PHP 7.4 is already out of maintenance / end of life, PHP 8.x is highly recommended. I have had no issues running DokuWiki on PHP 8.2 and 8.3 so far.

So far the most troublesome issues seem to be:

• parsing of formated tables fails in Dokuwiki 2024-02-06 "Kaos" (#4186)

  • This can be a show-stopper. But a fix already exists:
  • fix overeager optimization in Table handler. fixes #4186 (PR #4188)
  • ✔ Fixed in DokuWiki 2024-02-06a "Kaos".
• Wiki Logo aspect ratio broken after update to 2024-02-06 "Kaos" (#4187)

  • Specific to the DokuWiki Template.
  • fix logo aspect ratio and printing. fixes #4187 (PR #4189)
  • ✔ Fixed in DokuWiki 2024-02-06a "Kaos".
• It may be a good idea to invalidate the DokuWiki cache after the update. This can be accomplished by simply saving the Configuration (no actual changes required).
• No Content-Type header sent by Kaos' feed.php (#4203)

  • use correct FeedOptions methods. fixes #4203
  • ✔ Fixed in DokuWiki 2024-02-06a "Kaos".

Plugins work fine for the most part in my experience. But many plugins have not had their plugin pages updated to indicate compatibility with "Kaos" yet. And PHP 8 compatibility still needs work for some plugins, though the issues are mostly PHP warnings.

I can't comment much on templates, but sprintDoc Template and of course the built-in DokuWiki Template work fine.

Update 2024.02.12: Less than a week after the initial release, the hotfix version DokuWiki 2024-02-06a "Kaos" has been released, fixing the problems mentioned above. It may still be necessary to invalidate the DokuWiki cache after the update.
