Guys,
We just wanted to let you know that the Narayana code base (i.e. trunk) has moved over to github:
https://github.com/jbosstm/narayana
There are some notes on this over on our website:
http://www.jboss.org/jbosstm/sourcecode
Of particular note is that the 4.x and earlier versions of JBoss Transactions remain unaffected by this change. If you are working on a branch in a currently released version of JBTM then don't worry - nothing should have changed!
If the link to our site (and the link out to the Hacking on AS7 guide) doesn't answer your questions, please do raise any questions here and I will get the relevant documentation updated.
Happy coding!
Tom
Corrected the typo in the header, kudos to @npfr for pointing this out.
