mediasoup 3.11.8 fixes an important bug which caused video to be frozen when the `Consumer` switches to another preferred spatial layer and there were RTP timestamp issues in the received keyfarme.

- `SimulcastConsumer`: Fix frozen video when syncing keyframe is discarded due to too high RTP timestamp extra offset needed ([PR #999](https://github.com/versatica/mediasoup/pull/999), thanks to [@satoren](https://github.com/satoren) for properly reporting the issue and helping with the solution).
