JDecisiontable 2.3.0 (final) released

Today I released JDecisiontable 2.3.0 (final). I added the necessary tests and they all were OK. The only thing I had to correct was that I forget to give the objects behind the menu items "Undo" and "Redo" names. This doesn't affect any user, just the test automation.

Yesterday I had an idea how to generate source code from a test specification and about an additional check for decision tables. Lets see.

Changing the LICENSE.txt to add the year 2015 I realised that I am sitting down coding JDecisiontable since 2011.
