Pyskool 0.5.1 has been released. The download page is the place to go to get a copy.

0.5.1 is a bugfix release. In 0.5 there is a bug that makes the game crash when the teacher has returned to the blackboard during a non-question-and-answer lesson after fetching the truant Eric; this bug is now fixed. Saved games from version 0.5 should work just fine in 0.5.1, too. Thanks to Ben for reporting the bug.
