Hugin 2016.2
* Allow reading of image positions from Papywizard XML files.
* Internal blender and verdandi got the possibility to blend seams as alternative to
  current hard seam.
* The display of the control point error (after optimizing and in fast preview window)
  and the control point list window can now limited to take only control points in active
  images into account (menu Edit>Optimize only active images, connected with the setting
  on the optimizer tab).
* Improvements to mask tab in Hugin (edit crop of all images of the same lens at once) and
  find panorama dialog in PTBatcherGUI (remove images from found panoramas, split found
  panorama into two).
* Several improvements for Mac OS.
* Fixes several issues with fast preview window which could result in random crashes
  (uninitialized variables, memory leaks).

============================================================================================
Hugin 2016.0
* Added user defined output. The user can define own output sequences to implement
  new use cases, e.g. zero noise output.
* Added --clip-exposure switch to nona to automatically mask over and under exposed
  areas in input images.
* Color management
   ** GUI tools (Hugin, calibrate_lens_gui) take ICC profiles in files and monitor 
      color profile into account to display images.
   ** celeste and cpfind converts internal image to sRGB before working.
* Some buttons got a context menu for easier access to some function
  ** Show all in fast preview window to allow better interaction with stacked projects
  ** Celeste in cp tab: the button can now create cp or clean cp  
* Updated internal levmar library to version 2.6
* The identify tool in the fast preview window shows now also the image numbers on top
  of the images. (This can be suppressed by pressing the alt button).
* Fixes internal image format for GPU remapping. This should fix the "unsupported
  framebufferformat" error.
* Use own code for OpenGL intialization. Now freeglut is not needed anymore.
  (This should prevent the appearing of window when running "nona -g". Linux/Window only)
* Control point and mask editor retain viewpoint when changing zoom factor.
* PTBatcherGUI: Minimize to tray is now user configurable.
* Fixes a bug in photometric optimizer and merge projects with line control points.

============================================================================================
Hugin 2015.0
* stability and speed improvements
* new stitching engine
* new blender verdandi
* own camera and lens database
* preview window: new tool to add or remove control points
* automatic exposure stack detection when loading images,
* fine-tune and auto-estimate functions are now projection aware
* PTBatcherGUI: more options for end of process

============================================================================================
Hugin 2014.0
* inherit many of the libpano improvements (of version 2.9.19)
* the translation plane variables Tpy and Tpp have been added to the GUI 
  (better support for translation parameter, e.g. for nadir images, also pano with 
  translation parameters can now rotated)
* improvement of the GPU remapping code (bug fixes in the glue code, added some missing
  GPU transformation, now also fisheye lenses are supported by GPU code)
* better support for line control point in Control points tab (it still requires that 
  the same image is displayed left and right for full features, but also better support 
  for line control points above several images)
* obsolete programs matchpoint, nona_gui and PTBatcher have been removed
* outdated translation have been removed from the default install
* initialize the colour balance values during loading with EXIF values 
  (this information is only stored and decoded by some cameras 
  (mainly models by Panasonic, Pentax, Olympus, Nikon))
* improved the assistant
* allow customization of exiftool command used to copy metadata to output images
* new command line tools for CLI processing
    ** pto_mask: manipulate mask in project file
    ** pto_template: apply template to project file
    ** pto_move: move or copy project files with all associated images

============================================================================================
Hugin 2013.0
* Redesign of the User Interface: The User Interface now features a Simple, Advanced and
  Expert interface.
* New tools added:
   ** pto_var ( change image variables inside pto files)
   ** pto_lensstack (modify assigned lenses and stack in pto files)
   ** geocpset ( add geometric contraints for multirow panorama with featureless images)
* Completely rewritten internal helpfiles to reflect new User interface(s) and functionalities
* many bugfixes
