In last week of March, Apple started seeding Mac OS X 10.5.3 beta to the developers. This Friday Apple seeded the latest beta version of Mac OS X 10.5.3 (9d19) to the developers. The latest version includes 31 new bug fixes affecting Airport, Back to My Mac, Spaces, Time Machine and many other features. Actually Spaces has been behaving weirdly on both of my laptops since 10.5.2 update, I hope they fix it soon, as it is one feature of Leopard that I have used the most. It is believed that Mac OS X 10.5.3 we be released next month as a free update to existing Mac OS X 10.5 users.
