Apple today released an updated version of OS X 10.9.1 for developers, which has a build number of 13B40 . Today's release comes nearly two weeks after the second 10.9.1 beta, which had a build number of 13B35.

13b40
Last week’s build included several fixes for Gmail in OS X Mail, along with improvements to the Smart Mailbox functionality. It also included bug fixes for emojis when used with VoiceOver, and included an update to the Shared Links tab when the Safari Sidebar is open. Build 13B40 includes the same fixes.

Registered developers can download the update through the software update tool in the Mac App Store.

Lay this one at the feet of Google

I think they did that on purpose to sabotage Google. LOL.

Uh, no. Google did it because they can't write decent software, and can't resist the urge to use their own non-standard implementations of common standards. Fine if you make it better, but Google… doesn't.

Oh Really it came from Apple and is not warez: https://appleseed.apple.com/sp/downloads/projects/1000715/downloads (https://appleseed.apple.com/sp/downloads/projects/1000715/downloads). If you follow the link and log in with your Developer ID you can download the Feedback Assistant.

Plus I got the beta and updates through the Apple App Store!

No. ADC members do not have Apple Seed logins. Nor do they have a feedback utility. We report bugs using the bugreporter website.

Are you also confused, that Apple has people working on any other software products, marketing, hardware design and customer support, and people doing gardening and catering, all the while there are bugs in OS X that need to get fixed?

Most roles are highly specialized, and not interchangable, not even within the same product team. So someone working on the emojis could not just quickly be thrown to work on memory management and file systems, without familiarizing them to those parts of the system. It would take time and resources to train them, and that would not help getting bug fixes out any quicker.

Having someone fix a bug in the part of the system they are specialized in, is not going to slow down the improvement in other areas.

Exactly. See also:

Brooks's law is a principle in software development which says that "adding manpower to a late software project makes it later". It was coined by Fred Brooks in his 1975 book The Mythical Man-Month. The corollary of Brooks's Law is that there is an incremental person who, when added to a project, makes it take more, not less time. Brooks adds that "Nine women can't make a baby in one month".
