5.0.0.536 was the TAP beta for 5.0. The TAP is a very early release made available for some select customers in order to gather early feedback in a controlled manner.  In some cases, which includes this release, the release is not yet feature complete.  There was a subsequent beta, sometimes referred to as the public beta, a beta refresh. or sometimes as beta2 by Microsoft. The release was distributed using Microsoft Connect, requiring signing up and requesting the download, which was available only by invitation.
