In this release, we changed the default behavior of double click to zoom toggle instead of switching to Contact Sheet. You need to turn off "Switch to Contact Sheet by double clicking on the main window" under "Preferences... > Advanced" settings in order for this to take effect.
Finally the bug causing one-month trial to expire immediately for users in the non-English region is fixed.
ExifTool has been updated to version 11.99.
We have removed the support for macOS 10.10 and 10.11, as we are planning on some new features in a future release.
