  without crashing as often

  minor memory leaks and some corner case bugs in the process
• A bunch of masks corner cases fixed
• Tonecurve no longer clamps the gamut
• Assorted TIFF reader/writer fixes
• Map view: only connect to the map server when active
• Use filesystem timestamp for images lacking EXIF
• Sync AMAZE code from RawTherapee, now with SSE2 optimization, so it’s less
  slow

  cameras (requires images to be re-imported)

• Experimental support for Nikon D5300
• Experimental support for Nikon D3300
• Experimental support for Samsung NX1100
