Messenger Plus! does not release new versions based around MSN Messenger and Windows Messenger releases. A small fix will be released to fix compatibility bugs. I can assure you that it has not been sent to beta testers and when I last spoke with there was no ETA on the release of the Beta but possibly may be soon.
Next time I talk to Fraisie and/or Patchou I will see if they have a rough estimate about the date.
