This issue will be used to track a back porting effort to the 10.5 branch. Issues to be fixed will be linked and reopened. As engineers back port fixes they can temporarily assign issues to themselves and the assign them back to the original own.
The linked issues are suggestions, based on a rough analysis. Please look closely at the issues you pick to back port. If they end up being technically difficult or have behavior changes it may be entirely appropriate to remove them from the list.
