Ars Technia first turned me on to the new developer build for Mac OSX is out there.
Looks like the build has over 100 fixes, but Apple is still asking for input concerning Mail.
Apple is asking developers to bang on MobileMe’s automatic syncing feature with portable Macs and on networks with medium-to-high latency or constrained bandwidth. Apple wants to hear from developers who work behind firewalls and corporate proxies, and it’s also interested in hearing if changes sync between Macs and the MobileMe website within “a reasonable amount of time” when automatic syncing is turned on.
So, have at it dev kids.
