[interface part]
application is adapted for windows 10 because it is impossible to write to the files where the program is installed
due to algorithm changes, the application will only work on 64-bit windows
added mathematical expectation calculator for the value of contracts for the option "solve all the deals"
option "solve all deals" has been added for bridge. Pair of players with unknown cards can be chosen, cards of players can be fixed. You can do a search when the pair has at least one card left
option "solve all deals" was expanded for preferans, now you can do a search when there is at least one card left for defenders
optimal moves panel added, which you can click on to make a several of them
added score calculator for preference
added support for decks and arrows in vector graphics format (svg files). Added raster/vector decks, raster/vector arrows
option to stop calculations while they are not finished has been added
added complete descriptions of bridge and preferans algorithms in Russian and English
you can read about all the changes in the new version on the website in the version history
the source code is published on github
added menu problem/open from library
added menu addons/reset settings
all moves evaluation function is accelerated for bridge since it has become multitasking, it now also uses a reduced search interval
export of calculation results to csv file was added for the option "solve all deals", also export of all deals with results was added
when new parameters are added to the configuration file, the old information is now read instead of a full reset, as before. In particular, when installing a later version over the old one, the old settings will be read and the rest will be set by default. The order of the lines in the file when reading is no longer important.
if there is no id in the language file, the number of previous id is taken and incremented by one
when reading a language file other than English and Russian, if the id is not found, then the corresponding string from the English file is used.
all bridgeX.css files are removed, and only one unchangeable bridge.css file is left
all settings affecting the css style are now stored in the config file.
aslov self-developed library is used, sources are published on github
picture of the first deck has been changed, the diamond became smoother (the picture is taken from the gambler)
when exiting from the application in case of incomplete calculation, the correct stopping of the search is called
because the deck can now be scaled, support for large monitors was added
set big deck by default for big monitors
changed the default font size depending on scaling
deleted the image of the cardback, now uses a scalable drawing
fixed bug, now it is impossible to switch tasks in the task selection panel during calculations.
fixed bug, now you can not call some menu items during calculations, for example, to open the task
fixed bug when saving/loading tasks when more than 50 moves are done.
bug fixed if a task was loaded without a contract, and then the language changed, the contract remains unset.
fixed a bug when calling the calculator of points for the bridge with the current preferans game, now there is no option misere
fixed bug in drawing of bottom, rounded table corner
fixed bug at increase / decrease of font size
fixed bug in rendering best moves panel with large deck and small font
tooltips make as status bar which allow avoid problems with long strings
fixed bug with dinamical adding/removing of analisys/last trick
Fixed a bug when selecting a background image that contains transparent pixels
problem saving to html file has been changed, if a file contains only one task. Now the number of the problem is not specified in the file, since it is not needed
reset language file, if path indicated in configuration file is wrong. Now when you move/rename a folder with the program, it does not hang
"Check for a new version" menu has been removed, as it is not needed
the application has been adapted to the gcc 10.3.0 compiler and gtk 3.24.30. In the new version of gtk, some bugs of the previous version of the gtk library are vanished
all static functions of Base class are made to global functions
[logical part]
the bridge problem solver has been completely rewritten
now you can solve several tasks in one process
since everything is solved in one process, synchronization of the bridge problems has been simplified
preliminary calculation of moves was added
added cutoffs of lower 4 layers in bridge and 3 layers in preferans, earlier it was 3 and 2 accordingly
32-bit numbers are now used as suit codes in bridge, they are used to find moves and also for hash table index. Previously, for suit codes used doubly linked lists, as well as parallel bit codes of suits, which were used to find the hash table index.
separate algorithms are added for games with trump, NT games and misere games for preference
for each type of algorithm the parameters for statistical ordering of moves are adjusted. Now the algorithm does not require a check on the type of game with or without trump, or misere for preference
in the internal representation trump, if there is one, is always zero for bridge and preference. Now only two card comparison tables are required instead of five, one for games with trump, the other for games without trump, including misere games
the application became 64-bit. As each object of the Bridge class requires about 280 MB of memory, if a computer has 6 or more cores, the 32-bit application would not have enough memory
the bridgeConsole project is no longer needed (it was removed)
the preferans task solver has been speeded up, read more details can be found in the description of the logical part
you can read more about all the changes in the new version in the logical part

[base changes]
table rotation by 90° for preferans game (selection place of abcent player) if click on absent cards or "addons" menu
option "solve for all declarers and trumps" for preferans now solves for all first moves, players and game type. First move was fixed in earlier versions
code for preferans is changes and became much faster, especially option "solve all opponent deals"
[interface part]

[logical part]

all source files were proceded using eclipse formatter. Source code became more readable
thread synchronization including console application is fully completed
