Andrei Zmievski shares some information about the "zeta" release of PHP-GTK 2 in his latest blog post (yes, that's right - zeta).

PHP-GTK 2 Zeta release, the first one of the new architecture, is finally out. No, zeta it's not a typo. What's a zeta? Well, it's a letter of the Greek alphabet. Why zeta? Because, a) we've gone through several "iterations" of this release without actually releasing anything, but more importantly, b) alpha and beta get all the glory in the software world, leaving the other Greek letters longing for a spot in the sunshine. So, zeta it is.

He also notes that he's been working on the project for over five years. Thanks Andrei for all of your hard work and dedication to the project - it's great to see this new long-awaited release finally happening!
