There is another build for yosemite 10.10.2. Yesterday we had build 14C68k. It has now been updated to 14C68m. Direct links for the delta and combo are now in apple's developer forums. The 14C68k links are still available through apple's developer forums, but NOT through the mac app store. You will need to redownload if you want 14C68m. Also, since the build numbers are so close, you may not be able to get 14C68m through the mac app store if you already have 14C68k installed. In this case, use the direct links instead.
