  features in the overlap area that can be used for auto-alignment.
+ Batch Convert: add an overlay image to output images (e.g. a credit line).
+ Slide Show: minor changes to improve user interface (see User Guide).
+ Image right-shift is now a user option with no more back-and-forth motion.
+ Search Images: new option for text data matching: case-sensitive or not.
+ New user option: default gallery sort: file name, file mod date, photo date.
+ A new function for color saturation was added (separate from Retouch Combo).
+ Bugfix: Search Images for metadata was including some non-matching images.

2015 Dec 20  v.15.12.1

2015 Dec 01  v.15.12
+ Adjust HSL menu: better control of the color range to select and adjust.
+ Fix Perspective: new option to automatically trim using the corner markers.
+ Trim/Rotate: new option: level a slanted image via EXIF RollAngle if present.
+ Keyboard Shortcuts: list all existing shortcuts in a popup window.
  A button is available to start a dialog to add or revise shortcuts.
+ Metadata short report: user can specify extra items to include in the report.
+ New: Metadata batch report - list selected metadata for selected image files.
+ File Save - New File Version: this function can now have a keyboard shortcut.
+ Maps: red-dot locations are consolidated only for separations < 100 meters.
  Previously location names were used, but this is sometimes too broad.
+ Maps: custom user maps are now separated from standard maps.
  This prevents losing them if the fotoxx-maps package is re-installed.
+ TIFF files are now saved without compression. The file size may be slightly
  greater or less, but the processing time is reduced 90%.
+ Slide Show: new transition: image turns like a book page to reveal next image.
+ Bugfix: the Upright function would not step to the next image.
+ Bugfix: PT Panorama was broken due to an interface change in Panorama Tools.
+ Bugfix: possible crash when leveling an image by dragging the image edge.
+ Bugfix: possible crash if a select area is abandoned with nothing selected.

2015 Nov 08  v.15.11.1
+ Bugfix: Rename failed to automatically open the next following file.
+ Translation updates: Spanish, Catalan, Portuguese, Italian.

2015 Nov 01  v.15.11
+ Folders in gallery pages show contained sub-folder and image file counts.
+ Pattern: pattern can imprint target image without changing image colors.
+ Adjust HSL: the amount of color change is proportional to the match with
  a selected target color, and this match range is adjustable.
+ Batch Convert: more flexibility in the formatting of output file names.
+ New: Spherical image projection with variable radius of curvature.
+ Trim/Rotate: if an image is leveled using mouse drag, the trim rectangle
  is automatically maximized, removing the need to do this manually.
+ If an edit dialog is started and left/right image margins are present,
  the image is pushed to the right side so the dialog can be positioned
  over the expanded left margin and menu panel, to cover less image area.
  This position is saved and restored the next time the dialog is used.
+ Saving to file type .bmp was removed, since all metadata is lost.
+ A new transition type was added to Slide Show: collapsing sphere.
+ Six other minor improvements and bug fixes.

2015 Oct 09  v.15.10
+ New: Batch Scripts: Perform a series of image edits while recording all
  menu and dialog inputs into a script file. Execute the script file to
  apply the same edits to multiple images selected from gallery pages.
+ Calibrate Printer: improved for slightly more accurate colors.
+ Edit curves: The capture distance for mouse selection of nodes to drag
  is adjustable (increase default value to make touch pads easier to use).
+ Batch Add/Change Metadata: a pick-list for commonly used tags was added.
+ Geographic maps: mouse distance to trigger a popup location name was
  made independent of map scale (10 pixels instead of 10 km).
+ Bugfix: gallery file selection: clicking on a file name in the list of
  selected files was sometimes inaccurate and selected the wrong file.
+ Bugfix: setting geotags by clicking on map locations did not allow an
  initial location to be revised by clicking somewhere else.
