History

The Baron has been released several times. And every time I hope it became stronger again. One thing that is true for all versions is that I solved problems, bugs, errors etc. Also true for all versions is that I added more knowledge. For details on the changes I refer to the appropriate file in the baron distribution. This place is only indicating the really big things that changed. Things that you can notice when using the Baron.

The main changes and release dates for each version are listed below.
