Along with the update to Mac OS X v10.3.3, Apple has released
to Mac OS X Server to bring it up to v10.3.3 also. The software can be installed either by using Software Update or through the use of a standalone installer; the standalone installer was not available as MacCentral posted this article but presumably will be soon, since it’s referenced in Apple’s documentation.
Changes to Mac OS X Server v10.3.3 include improvements to Open Directory, Network Services, General Networking, File Services, System Imaging, Printing, Mail Service, QuickTime Streaming Server, Server Administration Tools, Application Server, Finder enhancements, AppleRAID and more. Dozens of changes have been made — you can read all about them yourself at the link above.
Apple also notes that data stored in MySQL databases with the version of MySQL that is pre-installed with Mac OS X Server 10.3.2 or earlier must be exported and re-imported in order to be compatible with the version of MySQL included with Mac OS X Server v10.3.3. Apple said a byte-ordering issue is fixed in the new version, which necessitates the export and import procedure.
