This also fixes the bug that the game navigation with the mouse wheel was not disabled in rated games and the game could not be continued after that because the play button is disabled in rated games.
- It is no longer possible to select and play a piece while the computer is thinking, the thinking must be aborted first with Computer/Stop.
- Bugfix: program crashed if computer colors dialog was opened and closed with OK while computer was thinking.
- Experimental support for Android. The Android version supports only a subset of the features of the desktop version and only playing levels 1 to 7.

- The interface is now more locked down during rated games, for example it is no longer possible to change the computer colors or take back a move during a rated game.
- The menu item "Computer Colors" was moved from the Game to the Computer menu.
- The source code no longer compiles with MSVC 2012 but requires MSVC 2013 because a larger subset of C++11 features is used.
- The source code distribution now uses xz instead of gzip for compression.

- Fixed a crash that could occur if the window was put in fullscreen mode by a method of the window manager (e.g. title bar menu on KDE) and then returned to normal mode by a different method (e.g. pressing Escape)
- Increased playing strength at higher levels. The search algorithm used for move generation is now parallelized and can take advantage of multi-core CPUs (up to 4 cores). There is a new playing level 8, which has a 2 GHz dual-core CPU or faster as the recommended system requirement.
- New menu item Toolbar Text to configure the toolbar button appearance independent of the system settings
- More SGF game info properties (event, round, time) were added to the game info dialog
- The source code now requires at least GCC 4.7 (because a larger subset of C++11 features is used)
- The CMake module GNUInstallDirs is now used for setting the installation directories on Unix. Note that the defaults for bindir and datadir are now CMAKE_INSTALL_PREFIX/bin and CMAKE_INSTALL_PREFIX/share instead of CMAKE_INSTALL_PREFIX/games and CMAKE_INSTALL_PREFIX/share/games. They can be changed by setting CMAKE_INSTALL_BINDIR and CMAKE_INSTALL_DATADIR (bug #7)
- The source code no longer depends on the Boost libraries. However, it is still possible to use Boost.Thread instead of std::thread by configuring with USE_BOOST_THREAD=ON (e.g. needed on MinGW GCC 4.7, which has no functional implementation of std::thread)
- Thumbnailer registration for blksgf files is no longer supported for Gnome 2
- Small increase in overall playing strength at higher levels in all game variants (especially Trigon)
- The computer now knows about the possibility of rotational-symmetric tied games in game variant Trigon Two-Player (like it already knew in the variants Duo and Junior) and will prevent the second player from enforcing such a tie

- New functionality to compute a player rating for the user by playing rated games against the computer
- Different options for speed of game analysis
- New menu item "Play Single Move" to make the computer play a move without changing the colors played by the computer
- The mouse wheel can now be used to navigate in the current variation if no piece is selected
- Files written by older versions of Pentobi that use a deprecated format for move properties are now automatically converted to the current format on write
- Bugfix: File was erroneously marked as modified if a multiline comment was shown and the platform that was used to create the file had Windows-style end of line convention and the platform on which the file was shown had Unix-style.
- Fixed the corruption of non-ASCII characters in game files on some platforms.
- Fixed a case where the program froze instead of showing an error on certain syntax errors in the SGF file.
- Fixed duplicate menu shortcut in German translation
- Fixed too high floating point tolerance in unit tests.
- No more popup messages if a color has no more moves; instead, score points of this color are underlined (feature request #3431031)
- Newly supported game variant Junior
- Improved playing strength. Number of levels increased to 7. Level 7 is about the same speed as the old level 6 but stronger.
- New game analysis function that shows a graph with the estimated value of each position in a game (menu item "Computer/Analyze Game")
- Support for setup properties in blksgf files (note that files with setup properties cannot be read by older versions of Pentobi). A new setup mode can be used to create files that start with a setup position including positions that cannot occur in real games (e.g. for puzzles or Blokus art)
- New menu items for editing the game tree: "Delete All Variations", "Keep Only Position", "Keep Only Subtree", "Move Variation Up/Down", "Truncate Children"
- Variations are now displayed by appending a letter to the move number instead of underlining
- Added a toolbar button for fast selection of the computer colors without having to use the window menu.
- User manual is no longer compiled into the resources of the executable but installed in the installation data directory
- Open a console for stderr output on Windows if Pentobi is invoked with option --verbose
- New option --memory to make Pentobi run on systems with low memory at the cost of reduced playing strength.
- Use standard icons from theme
- Bugfix: program sometimes hung or crashed when generating a move in early game Trigon positions especially when there were no legal moves with any of the large pieces
- Bugfix: file modified marker was not set on certain changes (Make Main Variation, comment changed)
- Bugfix: game info dialog showed wrong player labels in Trigon and Trigon Three-Player * Minor other bugfixes in the code
- Reverted the change that used the SVG icon for setting the window icon because it created an unwanted dependency on the Qt SVG plugin.
- Made Save menu item and tool button active if game is modified even if no file name is associated with the current game
- Made the code compile without warnings with GCC -Wunused
- Made "make post-install" continue even if some commands fail.
- File is now immediately visible in Recent Files menu after saving under a new name.
- Fixed several cases where the program crashed instead of showing an error message if the opened file was invalid. The error message now also has a Show Details button to show the reason why the file could not be loaded.
- Fixed a bug that distorted the position values reported with --verbose if a subtree from a previous search was reused
- Fixed exception in tools/twogtp/analyze.py if option -r was used
- Minor fixes in computer player engine
- Added explaining label to computer color dialog because window title is not visible in all L&F's
- Accept pass moves (empty value) in files. Although the current Blokus SGF documentation does not specify if they should be allowed, they might be used in the future and are used in files written by early (unreleased) versions of Pentobi
- Extended the file format documentation by a hint how to put blksgf files on web servers
- Smaller icons for piece manipulation buttons
- Fixed computation of the font bounding box in the score display
- Set option -std=c++0x in CMakeLists.txt if compiler is CLang

- Support for game variant Trigon Three-Player
- Change directory for autosave file to use AppData (on Windows) or XDG_DATA_HOME (on other systems)

- Fixed small rendering errors
- New menu item Find Next Comment
- Added chapters about the main window and menu items to the user manual
- Fix bug: computer color dialog did not set colors correctly in game variant Trigon
- Show error message instead of crashing if the SGF file contains invalid move properties
- Lowered the required version of the Boost libraries in CMakeLists.txt from 1.45 to 1.40 such that Pentobi can be compiled on Debian 6.0. Note: some versions of Boost cause compilation errors if used with certain versions of GCC and option -std=c++0x (e.g. the combinations GCC 4.4/Boost 1.40 in Ubuntu 10.04 and GCC 4.4/Boost 1.42 in Debian 6.0 work but the combination GCC 4.5/Boost 1.42 in Ubuntu 11.04 causes errors).
- Changed installation directories according to Filesystem Hierarchy Standard (/usr/bin to /usr/games, /usr/share to /usr/share/games)
- New CMake option PENTOBI_REGISTER_GNOME2_THUMBNAILER for disabling the installation of files for registering the Pentobi thumbnailer on Gnome 2
- Install man pages for pentobi and pentobi-thumbnailer on Unix systems
- Support for the game variants Trigon and Trigon Two-Player
- Fixed saving/opening files if file name contained non-ASCII characters and the system used an encoding other than Latin1
- The score numbers now show the total player and color scores instead of on-board and bonus points separately (feature request #3431039)
- New menu item "Edit/Select Next Color" that allows to enter moves independent of the color to play on the board (feature request #3441299)
- Slightly changed file format to use single-valued move properties as used in other games supported by SGF. Files written by Pentobi 0.2 can still be read.
- German translation
- Display sum score for both player colors in game variant Classic Two-Player
