GraphicConverter 10.5.5
Lemkesoft has released GraphicConverter 10.5.5, adding a GPS menu item for finding other images shot near a selected image and an Edit menu item for finding and replacing duplicates of a selected file. The graphic conversion and editing utility also adds a batch action for removing metadata, updates texts and routines for writing HEIC files with macOS 10.13.4 High Sierra, improves export of DirectDraw Surface (DDS) files, and updates localizations. ($39.95 new from Lemkesoft or the Mac App Store, free update, 181 MB, release notes, 10.9+)
It says 'free update' but an 'upgrade' costs. Can you clarify?
It's a free update from any previous version 10, but there's an upgrade fee if you're still running version 9. Since that's always true, we stop mentioning the upgrade fee after first few free updates to a new major version.
