AppleInsider reports that less than two weeks after 10.3.6 was released, Apple is already circulating internal builds of 10.3.7. Reportedly to be released before year's end, developers should be receiving their first builds within the next few weeks.
While details surrounding these very early builds are scant, sources say Mac OS X 10.3.7 will deliver enhancements to FireWire Audio, OpenGL, CoreGraphics, Multicast DNS, mLAN Audio, CoreFoundation, and AppKit.
The update is also said to include revisions to the Mach Kernel, PDF and PostScript rendering, ATI Radeon graphics drivers (8500, 9700), and Nvidia GeForce graphics drivers (3, 2MX, FX).
[Update] - According to Think Secret, OS X 10.3.7 build 7S202 was released to Select and Premier developers late Tuesday night.
