Golf Quartz Mapper has been localized to 5 new languages: Chinese (Simplified), German, Japanese, Spanish, and Swedish.

Overall improvements for course variants creation and use, right on time for winter & seasonal green changes.

NEW FEATURES & ENHANCEMENTS
• Course Markings: Golf Quartz on iPhone now lets you mark specific locations on the course with the GPS into a geojson file to let you more accurately create maps in Golf Quartz Mapper (Mac). You can use it for instance to precisely indicate a winter green variant for each hole, and then get appropriate distance on the watch when playing that alternate green.

NEW FEATURES
• Hole group editing now allows splitting and merging.
• 18-holes groups now allow automatic front 9 / back 9 based combinations on the watch, unless they are marked with the new "indivisible" tag. These 18-holes courses can now be encoded as such, it is no more required to encode them as front and back subgroups.
• Modernization for macOS Sequoia.

BUG FIXES
• Fixed a bug where editing an affinity could delete it.

Added keyboard shortcuts and menu actions for changing map style and previous/next hole navigation.
