ActiveState's download page now offers the choice of 5.8.0 (build 804) alongside version 5.6.1 (build 633). The files are dated the second of December. The beta version was build 802 sometime in November. (The link above actually goes to the registration page before the download page).
Their ppm repository shows 4054 modules available. Release notes are here.
Why the question mark? I can't find any "official" announcement.
