Some excerpts from the Readme file:
-XTL 1500 and XTL 2500 radios are supported in this release.
-New "O5" control head is supported for the XTL 5000 radios. (R06.00.00 req.)
-Control Head background color selection for new radios supported. (R06.00.00 req.)
-HearClear supported. (WTF???)
-MPL supported. (R06.00.00 req.)
It also contains instructions on how to flash upgrade a radio to the new O5 control head. Since I don't know the forum legalities of cut & pasting readme text direct, I'll skip over that.
Granted, I've been out of the loop for awhile, so some of this may be old news.
