Major Milestone Release
ANTLR 4.4 is a major feature and minor bugfix update to ANTLR 4. The primary enhancement is the introduction of both Python2 and Python3 language targets, which you can access with -Dlanguage=Python2 from the ANTLR command line. For C#, please use Visual Studio plugin/tool that Sam Harwell has built.
Please note that tool error messages have been altered to remove unnecessary single quotes and we have added some more specific error messages.
This release includes a new build script called bild.py and was not build using maven. bild.py is a Python script I made that looks like a makefile and self bootstraps by pulling in the required bilder.py library from the net. See http://bildtool.org. On a unix box, just type "./bild.py all" to build antlr from source (if you are so inclined).
We highly recommend that you regenerate your lexers and parsers using the latest version of the Tool.
