This release contains some minor crash and stability fixes, in addition, we have also temporarily put our internal version of Flash Player back behind a flag. We plan on re-enabling our internal version of Flash Player by default on the beta channel in the near future.


We have also fixed a regression so that we no longer remember incognito zoom changes (Issue: 43107)
