Today, Apple released the eagerly awaited major Mac OS X update, Mac OS X Lion.
Members of the Mac Developer Program got access to a so called GM seed on July 11th. While Gold Master (GM) seeds are supposed to be exactly like their soon-to-follow market releases, this has not always been the case in the past. Apple did take the chance previously, to rush in some late-night patches between Gold Master and Release-to-Market (RTM) builds.
That is, why this year I resisted my natural temptation to immediately go for the GM seed.
The only way of finding out whether GM seed and RTM version are the same is to take a look at their respective build numbers, found in About this Mac > More Info > Software.
Oddly enough, it seems as if this year the RTM version is actually older than the GM seed. Mac OS X Lion GM Seed is Build 11A511 and today’s RTM 11A494.
What’s going on here? Did Apple in fact roll out a previous build and those who ran for the GM seed are one step ahead already? Or does Apple just not count as we humans do?
Even the App Store seems to recognize a newer version. If you try to download the release from a machine that runs the GM seed, you’ll get this:

Maybe Software Update will kick in after install and upgrade to 11A511. What do you think?
+++ Update +++
Turns out that if your Mac is connected to the Internet during setup, the installer will actually download an update and upgrade your build to 11A511.
