OpenTalk v26.2.0 released

[Albrecht Weiche]

We are happy to announce a new OpenTalk release: v26.2.0.

Release notes

Noteworthy Changes

This is the first release where the RoomServer is mandatory. It can
either be deployed as a standalone service or embedded in the
controller.

OT-Setup and OpenTalk-Compose deployments can be updated as usual.

Migration guides will be published with product version 26.2.1.

Browser compatibility

Only browser versions supported by their vendor are listed in this
matrix. We might add newer versions of browsers that are released while
the OpenTalk 26.2 release series is supported.
