I just upgraded to Gramps 5.1.4 today using the Fedora repository. The dialog box for adding a new place has an error in the processing of GPS coordinate fields. The field for entering a comma-separated string says the sequence is latitude, longitude. However, the field is parsed as longitude, latitude. This is a change from previous behavior.
Same on macOS - you have to change the files in the app bundle to apply the patch, they are located at the following location (in Gramps.app: Contents/Resources/lib/python3.9/site-packages/gramps/gui/editors/)
