A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Bug fix: When moving to a square on border of the board, the game thought it as valid input if the player was drag and dropping outside of the play area. Not anymore! Tweaking engine: Now the engine can think deeper at simpler positions, increasing it's strength at endgame positions at higher settings.
-Corrected the game colors, it looked a bit too flushed out. Here is comparison of old and new graphics:in 3D view comparison:-Disabled the old online multiplayer from the game menus as it's no longer working at all. It was using the old unity multiplayer that they deprecated. I try to see if I can replace it with a working one without working too hard. Currently the best way to play through internet is by using the steam remote play feature.-Small tweaks to the chess engine
Added new features for local multiplayer: Now you can choose your time limits from 1 minute to 2 hours and increment from 0 to 30 seconds per move. Also you can now play chess 960 on top of super 960 variant in local multiplayer mode. This is also recommended mode to play over internet with friends by utilizing steam's remote play feature (as the online multiplayer is old code and doesn't seem to deliver that well)
Now live! -Chess Engine AI got improved, it's better at end games and better at finding clever tactics. Also strategically more adept. Example FEN strings of new positions it could solve (you can for example use lichess site here: https://lichess.org/analysis and copy paste the fen strings to see the correct moves for the chess puzzles: r4r1k/1p1bbppp/1qp1pn2/4B3/3P3P/1P1B1QR1/P3NPP1/1K1R4 w - - 0 15 2N4k/5p1p/p4q1b/1p1P3R/2npQ3/P5P1/1P4KP/8 w - - 1 38 rn2k2r/1bQ1qpp1/p3p3/2bp4/P2N3p/2PB4/1P3PPP/R1B1R1K1 w kq - 0 1 6k1/p1P5/P1r5/2p1K3/8/8/2R5/8 w - - 0 1 r2k3r/pp3pb1/3p3p/1BpP2p1/Q7/P1P2q2/1P3
Improved a bit the AI at higher levels: - Made the AI think at lvl 10 for a bit longer, thus being able to spot a bit more - Made the AI more likely to start the game without combining every move - Made the AI less likely to sacrifice pawns at the start of the game - Fixed the issue where the game thought it's draw because of insufficient material if the other player has only KnightPawn piece left -Fixed the issue where the game thought it's draw because of insufficient material if the other player has only BishopBishop piece left https://youtu.be/TlXXa8_JcBw
Fixed the issue of game not remembering the selected game mode. Thanks to ACTIONBOMBA for reporting the issue.
Stream will start on Monday 21 September: 10:00am Pacific (UTC−07:00) that is 6:00pm BST (UTC+01:00) The stream will last 2 to 3 hours. I will setup a webcam and you can intract live with the developer.
Enabled mac and linux builds, as I managed to fix on mac and linux builds a major issue where the game gets stuck after completing the game. Fixed check detection when there's multiple rook+rook or bishop+bishop pieces. So now the game should work in these situations more reliably.

The bug fixes include: 1. Fixed a visual problems with En passant when observing a played game. 2. English grammar corrections to the tutorials, thanks to TraDukTer for a big help here. 3. Leaving a game in progress against the AI and then returning will not set the AI to 700 level anymore. 4. Made the shortcut icon much better, the old one was pretty bad as for some reason it wasn't very sharp. Now the icon is sharp and nice. 5. Updated Mac and Linux builds to 64-bit. Also, Mlyst Corporation is progressing quite well with the new game, I would estimate that it will get launched during the nex
The game has very few reviews at the moment, so if you've got any feedback, feel free to give it with a steam review! Thanks! :) It's a novel, creative and intellectually stimulating new kind of chess game. It might not look as juicy and tasty as some other games with flashing lights and fancy marketing materials, but this game is actually better for you. This game is like avocado, blueberries and other healthy foods, while most games out there are like chocolate bars with 50% sugar and 20% saturated fat and eating that stuff is just killing you slowly, even if it tastes better for a while. Yo
I first thought about increasing the price because of the huge content update, but then I thought that okay, lets cut the price instead, because that feels more interesting thing to do for me! So I cut the price! ːsteamhappyː
Fixed some issues brought by the new content of chess variants. For example.. -A couple of the variants didn't work. I tested the variants more to make sure that they work. -White 2d Rook+Rook piece had wrong graphics, it didn't have the same look as all the other pieces. -Pawn+Pawn piece was able to jump through pieces if it was on the 2nd rank (for white) or 7th rank (for black). (Pawn+Pawn piece couldn't be found from those places before the added chess variants).
Very happy news for you guys! This is not April's fool joke either! There is a new "Scenarios" button included right next to the start game button, that will give the player more chances to customize the game! https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/33746749/75763983beb261df17900265051bfeb8624dadd2.jpg Here is a couple of examples of what kind of chess variants are included: https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/33746749/381548322601dc2ea5815e15f66781a299a05c56.jpg and another one: https://steamcdn-a.akamaihd.net/steamcommunity/public/ima
