EasyAbc has now moved to sourceforge. You can find the project here. The latest version 1.3.6 was updated on December 25 2014. It includes an experimental program abccore.py which is now only available in the source code.
Binaries for Debian and Ubuntu can be found on Guido Gonzato's Abc Plus project web page.
I have updated a guide (originally written by Chuck Boody) with a list of the new features in EasyAbc_1.3.6 which you can find here .
We are indebted to Frederic Aupepin and J.W. de Jong who have contributed many patches as well as Wim Vree who has provided support for the MusicXml conversion functions.
