Bukkit

1.5:

• Fixed problems with Factions, which were also generating nasty error logs
• Hopefully fixed both WorldGuard errors (explosions, player building)
• Made some changes on remove-permissions thing
• Fixed problems with Iron Golem, Snowman, Wither spawning, - new permissions cc.allow.mobspawn works when player in creative gamemode places Pumpkin on Snow/Iron block, or when player in creative places skull on soulsand
• Added two new options in configuration:
• * memory-limit - Set how many blocks can be held in memory of server to improve performance
• * excluded-blocks - Set which blocks shouldn't be tracked when placed by creative players

None at this time.
