Nothing about it in the change log. But don't worry, if it was a bug with Garmin Pay adding money to your bank account it would have been fixed !! ;-)
Changes made from version 3.10 to 4.20:
Added support for Connect IQ SDK v3.0.
Added abnormal heart rate alerts. Enable these in Heart Rate widget > Heart Rate options > Abnormal HR alert. An abnormal heart rate will be detected if your heart rate exceeds the entered threshold for an extended period of time while sedentary.
Made improvements to pool swim distance accuracy.
Improved Bluetooth connection reliability when using an iOS device.
Fixed a critical issue where music would intermittently stop playing over headphones.
Fixed an issue where Total Ascent and Descent could be too low for certain activities.
OpenWaterSwimming better? Is the official Garmin Triathlon App (and multisport) now working correctly ? Some Problems with the Firmware or anything fine?
i hope today will be available version 4,20 in the EMEA, because If NO I need wait long time to update ,because will be without Connection to the internet , so Garmin please speed up ;-)
There is a comment on the Forerunner 935 v10.10 release which states "..We are continuing to investigate issues related to Open Water Swim accuracy. We are working with the GPS Chip manufacturer and hope to have an update to fully address this issue in the near future." At last they seem to have recognised that they have a problem
Updated to latest software, still the watch is under reporting altitude gain for me, Watch says 557m, corrected in Connect to 593m and Strava says 648m so nothing changed for me, that's a 30 mile bike ride, with gps and glonass, calibrated before I set off.

Don’t always assume the corrected elevations are correct. For instance, if you ride accross a bridge over a valley, the watch knows you stayed level, but the corrected elevations follow the map and think you went to the bottom of the valley and back up, rather than over the flat bridge.
