When upgrading between major versions (e.g., 0.5 to 0.7), you always have to newly process your databases. Since processing is pretty fast by now, it should not hurt too much.

Between minor versions in the 0.7 branch, the database file format did not change. You can copy your kombilo.cfg file (which contains, among many options, the database locations) to the new directory, and thus keep your databases, including all tags.

History/Change log


0.8.4 (November 2016)

Some small changes, among them

  • Fix how symmetries in search patterns (and of continuations) are handled
  • Add Stop buttons for sgf tree computation and for processing SGF collections
  • Add more tests

0.8.3 (November 2016)

Several minor changes, mostly to ensure compatibility with Mac OS X.

Added references to the comments at Go Game Guru.

0.8.2 (November 2016)

  • Reduce memory usage at several points: pattern searches, search history, processing
  • Improve user interface (thanks to D. Sigaty for several suggestions)
  • Improve handling of collections distributed among many folders
  • Add references to commentaries (Go World now complete; several books added)
  • Several minor bug fixes

0.8.1 (October 2016)

  • Add Windows Installer
  • Minor bug fixes

0.8 (October 2016)

Major changes:

  • SGF tree function in Kombilo: continue searching recursively for all continuations arising from some search pattern.
  • Add framework to translate the application to other languages (plus German translation)
  • Install Kombilo as a Python package via pip (so far, as a source distribution only, i.e., a C++ compiler is still required)
  • Reintroduce Custom menus as in Kombilo 0.5.
  • Improve date profile: more fine-grained information, several options configurable by user.
  • Organize pattern search history as a tree.

The source code is now hosted in a GitHub repository.


0.7.6 (October 2016)

Some small bug fixes.

0.7.5 (October 2016)

  • Fix a few small bugs, most notably fix searching for the empty board (thanks to Bram Vandenbon for the bug report). Thanks also to Gilles Arcas and Claude Brisson for sending bug reports with fixes included.
  • Switch code versioning system to Git, hosted in Github: Kombilo
  • Small changes to reflect updates in third-party packages (SWIG, jQuery).

0.7.4 (August 2012)

Fixed bug in search algorithm. Thanks to John Fairbairn for pointing it out.

0.7.3 (May 2012)

  • Add Find duplicates method.
  • Fix goto move method (Shift + Right click).
  • .sgf as default extension upon saving files.

0.7.2 (April 2012)

Bug fixes. Added mouse wheel support, and - on Linux - support for back/next mouse buttons. Option to always maximize window (Windows only). Updated references to commentaries.


Update from version 0.7 or 0.7.1 to 0.7.2:

While reprocessing your databases is not necessary for Kombilo to be working correctly, it will greaty speed up the date profile computation, so it is advisable to do this.

0.7.1 (April 2012)

Major changes:

  • provide a Windows installer.

Selected minor fixes:

  • Make reprocess export/import tags automatically.
  • Optionally put search history as a tab in notebook in right column. Thanks to crux@lifein19x19 for the suggestion.
  • Pass focus to boardFrame upon double click in game list. Thanks to crux@lifein19x19 for the suggestion.
  • Update references to commentaries.
  • optionally Kombilo avoids the use of Python Imaging Library (PIL). With this option, Kombilo can be made to work on Mac OS X. Thanks to RBerenguel@lifein19x19 for testing things on Mac OS.
  • Fixed some issues regarding the handling of bad SGF files.

0.7 (March 2012)

Version 0.7 brought lots of changes to Kombilo and Libkombilo, including


  • Kombilo now makes use of the libkombilo C++ library; it can search in variations, and search for move sequences
  • Tags for games
  • Show date profile for current list of games
  • Much better support for using Kombilo in your own Python scripts; several example scripts included
  • Update the GUI: nicer icons, keyboard bindings, better handling of large game lists, etc.


  • Use multiple processor cores/processors, if available
  • Allow tagging of games
  • Change the data file format the search algorithms use to make startup and searching faster
  • Many bug fixes and small improvements

Furthermore, there have been a number of changes to make the development process easier and more pleasant, e.g.

  • switch to Mercurial as the versioning system for the source code, and host the project on BitBucket,
  • use Sphinx for producing the documentation
  • use Fabric to make deployment easier

“0.6”: Libkombilo (2006)

There was no Kombilo 0.6 release, but in 2006 I partially rewrote the pattern matching algorithms, and isolated them from the graphical user interface. This made it easy to include it as a library into other programs. Since version 3.0 (2007) it is included in Drago.

The libkombilo library can ...

  • search for corner patterns, full board patterns, and patterns anywhere on the board, of course taking into account symmetries (rotation, mirroring), and -unless switched of- color reversal.
  • handle for any (square) board size.
  • search for continuations, i.e. you give an initial pattern (possibly empty), and then a sequence of moves which have to occur in every hit in the given order.
  • search in games with variations, and find results within variations as well.

0.5 (2002-2004)

  • Kombilo comes with a complete SGF editor: so you can add variations of your own, comment the game, add labels etc. The SGF editor can also handle collections, i.e. SGF files containing several games. The tree structure of the current game is shown in a separate window. You can rotate/mirror SGF files.
  • Kombilo now comes with a built in list of references to commentaries of games in the English go literature. (NB: Kombilo does not come with the game records, but recognizes the games by the Dyer signature.) Those games in your database which Kombilo finds in its list are marked in the game list, and in the game info a reference to the journal/book which has the commentary is given. Currently the list contains around 1200 references, and includes references to the game commentaries in 85 issues of Go World and in most English go books with game comentaries.
  • The previous search patterns are now shown on small boards in a scrollable separate window. Thus you can switch back and forth between different search patterns much more easily. This also works much better now with different SGF files. In particular, you can load games from the game list directly to the Kombilo main board, and then search for patterns which arise in that game.
  • You can sort the game list with respect to one of several criteria (besides the default, sort by filename, you can now also sort by date, white player or black player). You can also easily change the order of the databases.
  • You can refine pattern searches by filtering who moves next in the search pattern.

0.4 (2002)

  • Custom menus: menus which you can edit yourself. Upon selecting a menu entry, the following actions can be performed: search for a predefined pattern; search for predefined game information (player, event, ...); open the web browser with some html file. Thus you could create a “Fuseki/Joseki pattern” menu, a “Players” or a “Titles” menu.
  • Even faster SGF parser. (On my computer, Kogo’s joseki dictionary now comes up immediately.)
  • Better handling of large databases.
  • First SGF editing features: you can now edit the game information, and the comments. (Make sure to have backups of important files ;-) )
  • Optionally include the whole game list when exporting search results.
  • Indicate color swap in the list of results
  • Searches with lots of matches are considerably faster now.

0.3 (2002)

  • The search engine has been partially rewritten; in particular two subtle bugs have been fixed. The use of hash tables makes joseki and fuseki searches considerably faster.
  • A faster SGF parser. With the new parser, Kogo’s joseki dictionary, a huge file, can be read in in a few seconds, and thus can be conveniently used with Kombilo to study Joseki.
  • Winning percentages for continuations; show how often some continuation is played after tenuki.
  • Export function for search results (either as plain text, or in a format suitable for use in Sensei’s Library)

0.2 (2002)

  • More comfortable game info search (time period, players, event, ...)
  • ‘Back’ button to return to the previous search.
  • More convenient user interface. In particular, the two windows will fit on your screen (800x600 or bigger) without overlapping now.
  • Display Black/White winning percentages. More detailed statistics on the continuations in a search pattern.
  • Check for duplicates in the data base (with the Dyer signature), search games by signature.

0.1 (October 2001)

The first Kombilo version. It already had the basic pattern search functionality (including the C++ extension), but was still rough around the edges.
