Apple Seeds First Version of Mac OS X 10.5.4 to Developers
Only one week after the release of Mac OS X 10.5.3, Apple has already started seeding developers with the first version of Mac OS X 10.5.4 (build 9E6). The latest developer seed lists no known issues and details only a handful of fixes to Mac OS X. Apple appears to be aggressively seeding developers with the latest builds of Mac OS X and waiting only days between builds.
This release comes only days head of Apple's Worldwide Developer's Conference which is rumored to introduce us to Mac OS X 10.6 (Snow Leopard), Apple's next major Mac OS X version. As typical, Apple will continue to work on bug fixes on the current version of Mac OS X while the new version is readied. There is no known timeframe for the 10.5.4 release but Apple can wait months between these maintenance releases.
