This is true; in the original AEL, a semicolon must follow EVERY
statement, even statement blocks. IN AEL2, the ';' after a statement
block is treated as an empty statement, and is ignored.

I am sure you will bump into other subtle differences... If I were to
try to enumerate them, I'd probably miss something, but I did give a
list of differences in the AEL2 voip-info Wiki... I congratulate you on
taking on this effort, and wish you all the success possible. If you
have any questions, feel free to write/irc/jabber/phone me. I'm
'usually' around.
