Apple today released a second golden master candidate of OS X Yosemite to developers, a week after releasing the first candidate golden master and the fourth public beta. Apple has also released the fifth public beta to those who signed up to beta test the new Mac OS.
The latest Yosemite update, build 14A386a, can be downloaded from the Mac App Store and through Apple's Mac Dev Center.

Over the course of the beta testing period, each Developer Preview has added new features and refined the look and performance of OS X Yosemite, although changes have become less obvious in more recent builds as Apple begins finalizing Yosemite ahead of its public release, which is expected in late October.
The current build, like the previous golden master candidate, may not be the final version of OS X Yosemite, depending on the outcome of final testing. Last year, Apple seeded multiple golden master versions of OS X Mavericks, with the final version coming a couple of days ahead of the software's public release.
