I'm happy to announce that version 3.0 of the
OpenG Message Queue (oglib_msgqueue) library was just released.
The message queue generates a response notifier to reply to messages.

You can find details, including change log and release notes, on the wiki, here:
Thanks to
Chris Relf (crelf) and
Antoine Chalons (TiTou) for identifying and fixing the issues resolved in this release.
You can download and install this library (as well as all the OpenG libraries) using
VI Package Manager.
