DocBook 5.2.1ꞵ1

Volume 10, Issue 12; 06 Mar 2026

Testing the DocBook 5.2.1 release.

On Monday, I proposed doing a DocBook 5.2.1 release to fix a small backwards incompatibility introduced in 5.2. I spent a few evenings this week reworking the build system and tidying up some of the loose ends. I ported the repository to Codeberg, added some tests, fixed the bug, fixed a couple of small Schematron issues, configured CI, and…published DocBook 5.2.1b1. I also pushed the betas of DocBook and DocBook Publishers to Maven.

Please kick the tires (excuse me, “tyres”) and report anything odd that you find. I’m confident that the actual schema changes are fine, but there are a lot of details in the build and release process (are the right files in the release packages?, are the catalogs correct?, is the little bit of Java shim correct?, etc.). I checked and double checked them, but by the time you’ve checked something a dozen times, it’s easy to see what you expect to find, rather than what’s there.

Next, I’ll see about updating the documentation and maybe exploring a few other small fixes.
