DocBook V5.1 Beta 4

Volume 14, Issue 25; 24 Jun 2011

Announcing DocBook V5.1b4, the fourth beta release of what will become DocBook V5.1. Version 5.1 includes significant new features for topic-based authoring as well as a number of bug fixes.

DocBook V5.1b4 is an incremental test release. If you've been experimenting with assembly markup, you will find that its changed somewhat. I think this is an area that's finally beginning to stabalize, but I wouldn't go so far as to promise that there won't be any more changes.

I've also published an updated DocBook: The Definitive Guide that documents the current beta.

Questions, comments, etc., most welcome on the DocBook mailing list.
