# Description

There were some recent updates to a couple of our dependency packages
that have updated their licenses. Updating our license checker
exceptions to match with the new updated licenses for these packages.

Additionally, adds a note in the simulation performance documentation
for CPU governor setting to improve performance.

Also, updates a few unit tests to mark as flaky as we've shown in recent
CI runs.
