indeed, Patchou has said that a msgplus, compatible with messenger 7, will be released by the end of the month IF all things go well. But this was before MS retracted messenger 7 and made it downgrade to 6.2 for serious security issues!!
So, I wouldn't be surprised at all if the compatbile-with-messenger-7 version will not be released by the end of the month. Because it would be stupid to release a thing while messenger 7 shouldn't be used in the first place.
The version that is going to be released this sunday 10th october (on Patchou's Timezone!!!!) is version 3.21. It will contain
some added features to the floating contacts and several bug fixes. It will
NOT be compatible with messenger 7.
As he also
announced on the forums, in this 3.21 version there will also be some changes in the sponsorsetup as a test. When the test is finished, a new version will be released (3.25 or something), still not compatible with messenger 7 for above reasons.
All the rest is nothing more then rumours and speculation...
