After 3 months as [release candidate], yesterday we release the 1.0.8 [stable] version of the BigBlueButtonBN and RecordingsBN modules for Moodle 2.x.
https://moodle.org/plugins/search.php?s=bigbluebuttonbn
And because apparently the changes that were made to Moodle 2.4 don't affect those plugins, we can say that both are 2.4 compliant.
Did you installed 1.0.8-rc1 on your Moodle 2.4?, If you did so, did you experienced any specific problem related to a version conflict?
if you did not installed the previous version, give a try to the new one. And let us know if you find any bug.
If this is your first contact with bigbluebutton please first take a time to look at the videos and documentation provided for both, the plugin
https://moodle.org/plugins/view.php?plugin=mod_bigbluebuttonbn
and BigBlueButton
http://demo.bigbluebutton.org/
