There are no known bugs in Alan 3.0beta3, there are over 1200 testcases that are run before each build is made available, so nothing much slips through.
But, if you are using an older interpreter to run a game produced with the alan3.0beta3 compiler, the interpreter might crash if the game uses attributes for the entity class. So it is actually a backwards compatibility problem rather than a bug.
Alan v3.0 beta3 is now available. Alan has been updated with what will probably be one of the last Beta versions before going 1.0 (planned for February 2014!). You can view the details of the changes in the Changes section. Windows downloads are available right now, with Linux and MacOSX coming in the next few days.
Today the AlanIDE was released with some updates:
Anssi Räisänen finished 13th out of almost 40 entries in the annual IFCOMP. "Ted Paladin and the Case of the Abandoned House" was developed using Alan v3 and the extensive library provided by Anssi himself. The game introduces a novel dimension of discovery.
