TSPSG v0.1.4 beta 2 (build 170)
-------------------------------

### What's New ###

  - Support for embedded base64 encoded images when saving solution as
    HTML ([Ticket #4][]).
  - The ability to setup page-related options for printing
    ([Ticket #5][]).
  - Solution graph size can now be controlled using `Output/GraphWidth`
    setting in tspsg.ini. Value is in centimeters. ([Ticket #8][])


### Changes & Improvements ###

  - Any value that is entered into task table and doesn't contain
    numbers is considered an infinity.
  - Some error messages are more verbose.
  - Removed a prompt about turning off language autodetection when
    selecting a language.

### Bugfixes ###

  - [Bug #2][]: Solution graph is too small on high resolution screens.
  - [Bug #3][]: Solution graph font size should be fixed.
  - [Bug #6][]: Bug: Actions in Options Menu.
  - [Bug #7][]: No Cancel option in Unsaved Changes dialog under
    Symbian.

TSPSG v0.1.3 beta 1 (build 145)
-------------------------------

### What's New ###

  - Solution graph generation.
  - Support for switching between available Qt styles.
  - Toolbar customization support (only on desktop platforms).
  - An option to remember last used directory when saving and opening.
  - Automatically check for updates at the given interval option (only
    on Windows platform at this moment).


### Improvements ###

  - Improved the solution output generation algorithm. It is now about
    1.65 times faster.
  - Dragging and dropping task file on the main window now opens it.
  - The deafult output font is now DejaVu LGC Sans Mono and it comes
    "embedded" in the executable.
  - The current desktop icon theme in Linux is now used if it follows
    freedesktop.org icon theme and icon naming spesifications.
  - Translations are now "embedded" in the executable but may be
    overrided by placing files with the same names in l10n folder.
  - Support for Windows 7 Taskbar Extensions (namely, Progress Bars).


### Changes ###

  - About dialog was "tabified". Added GPL License and Credits tabs.
  - Platform dependent settings (e.g. paths) are saved per-platform.
  - 32x32 icons are used on handheld platforms. This slightly decreases
    the size of handheld versions. Desktop icons are still 128x128.
  - Windows binary builds were moved from MSVC to Mingw-w64: no more
    Visual C++ Runtime dependency.


### Bugfixes ###

  - Solution related actions not disabled when solution is canceled.
  - Autosize setting was never saved and was always on.



TSPSG v0.1.2 alpha 2 (build 100)

  - Symmetric mode: in this mode the cost of travel from city 1 to
    city 2 and vice versa is the same.
  - Printing of solution results (if the platform supports it).
  - Saving solution to PDF (if the platform supports printing).
  - An ability to reset all settings to their defaults: hold Shift
    while clicking Save button in the Settings Dialog.
  - An ability to generate fractional random numbers.
  - An ability to set the fractional accuracy (in decimail places).
  - An ability to select between using native and Qt's file dialogs
    when opening and saving tasks and solutions.
  - An ability to disable showing of the solution steps' matrices in
    solution output.
  - An ability to enable scroll to the end of the solution output after
    solving.
  - An ability ot enable automatic resize of columns and rows to their
    contents on its change.
  - Basic support for Symbian.
  - Check for updates functionality (only in Windows version at this
    moment).


### Improvements ###

  - Improved the solution algorithm.
  - The maximum number of cities in task was increased to 50.
    NOTE: Showing the solution steps' matrices is disabled by default
    for tasks with more than 15 cities to considerably speed up the
    generation of the solution output process.
  - List of alternate candidates for branching is now displayed.
  - Warning about possible non-optimal result.
  - Open a file, passed as command-line argument.
  - Currently opened file name is displayed in the Main Window title.
