A new version of DocBook XML, the XML version of the popular technical documentation DTD, has been released by Norm Walsh.

Largely a maintenance release, changes in version 4.1.1 over 4.0 include:

• Fixed system identifiers in docbook.cat
• Added version information to all the ent/*.ent files
• Fixed a number of numeric character references in the ent/*.ent files
• Fixed a couple of incorrect FPIs.
• Renamed dbgenent.ent to dbgenent.mod for parity with SGML version

Officially, docbook.org is only a mirror of the main OASIS site, but as OASIS are still down with technical problems, the docbook.org site should be used for finding information about DocBook in the meantime.
