Just 3 days since the last seed, Apple has released the next build of Mac OS X to developers. Again, no "known issues" are listed in the latest developer build (9D23). Only 8 fixes are listed in the notes provided by Apple.
Typically, Apple has waited several builds before re-seeding new versions to developers. In the past, rapid-fire seeding has meant that they were prepping for the final release. It's unclear if Apple has simply changed its policy and seeding more frequently.
