Server logging now appends to server.log rather than overwriting it.
Fixed minecarts and pigs moving twice as fast as they should when ridden.
Trivia[]
When Notch released 1.2.4, he accidentally labeled it as 1.2.3_05 in game. This version also had leftover debug code that caused creepers to be the only mob that would spawn. This was later fixed with the release of 1.2.4_01, which means there was never a client version of 1.2.4.[1]
