Minecraft 1.5.2 is almost here, with loads of bug fixes in tow. This release has none of the new features seen in recent 1.6 snapshots, it is simply a continuation of the 1.5x releases. New in this update are fixes for decreasing jukebox music, de-spawning tamed animals, floating arrows, and more. You can get the Pre-release from the source link below or from the revamped Minecraft Launcher used in recent snapshots from here.
