This release contains a few bugfixes and one major compatibility improvement:
Aurous Ice (the gold kind) now correctly breaks and drops when mined with a pickaxe
Pedestals no longer desync between server and client when playing on multiplayer
Chorus Crabs now naturally despawn when far away, unless the player breeds them, feeds them or names them
Lighter End is now compatible with TerraBlender and mods such as Biomes O'Plenty, though you may want to adjust your TerraBlender settings to increase the size and abundance of vanilla biomes.
