Release notes 15.2

With OpenOlat 15.2 we release our next major release. It includes extensions in the BigBlueButton module, for example, recordings can be released for specific user groups. For the processing of the BBB-recordings an additional handler was integrated, which stores the recordings on an Opencast server. Recordings from the Opencast server can be integrated into OpenOlat via a separate Opencast course module. Besides minor adjustments the multi-window mode was further improved and if necessary the username can be changed in OpenOlat.

Overall more than 30 new features and improvements have been added to OpenOlat since release 15.1 and many processes have been improved. Here, you can find the most important new features and changes. In addition to these improvements, more than 20 bugs have been fixed. The complete list of changes for 15.1 – 15.1.4 can be found here.

BigBlueButton - Extensions

If BigBlueButton meetings are recorded, the publication of the recordings can now be controlled specifically. For this purpose, a list of participants is kept for each recording, which makes it possible to release the recording for different groups of participants:

  • Owner and coach
  • Course and group participants
  • All participants of the meeting (except guests)
  • Guests

In addition, an infrastructure was created that allows BBB recordings to be stored on an Opencast server. A re-integration of these recordings at other OpenOlat locations is possible via the Opencast module.

Course element Opencast

With the course element Opencast, recordings of meetings and courses stored on an Opencast server can be integrated into OpenOlat courses. The configuration and connection of the Opencast server is done in the administration. In the course element either single videos or whole series can be integrated.
