There's been no official communication yet by the Qt developers whether the long-awaited release of Qt 5.0 will happen this week (maybe it will happen with the end of the world on Friday with E17 1.0?). Shared on the development list this morning was a brief message that there's some new Qt5 spins for testing. "There is new version available for testing."
There isn't any official change-log for the latest Qt packages that are tagged "2012-12-18-389" but simply in the directory are the binaries for Linux, Mac OS X, and Windows along with the Qt sub-modules.
Qt 5.0 was supposed to come this past summer but its release and development has been riddled by delays along with the tool-kit changing hands from Nokia to Digia.
