Just a quick note for all of those Windows users out there from the main PHP site:

The 12th build of the extended CHM edition is out now, and available for download. This build contains updated content and user notes, as well as fixes the bugs found in the previous build. A new optional "phpZ" skin is also introduced in this release, courtesy of Gonzalo De la Pena Andreu. For more information, visit the homepage of this edition.

So, for everyone using the Windows Help formatted manual, you might want to update and get this latest version to ensure correct information. Enjoy!
