Chessolve 6.6.0 — Changelog

This changelog covers development from September 20 to September 22, 2026.
In total: 59 commits across 67 files, with 10,181 additions and 452 deletions.

⚡ More reliable live analysis on Chess.com

Chessolve now follows the real-time game stream used by Chess.com during live human games.
The complete move history from that stream becomes the primary source for the current position, replacing many timing-sensitive guesses based on visible page updates.
Opponent moves can reach Chessolve before the move list finishes updating on screen.
A page refresh in the middle of a game can recover the full position and move history from the next game update.
Castling, captures, promotions, and en passant are reconstructed by replaying the confirmed moves with normal chess rules.
Every update is checked before it is trusted. If the stream is unavailable, delayed, or inconsistent with the displayed game, Chessolve falls back to its existing board-reading path.
Bot games, puzzles, and other Chess.com surfaces that do not provide this live stream continue to use the established fallback.

♟ Instant response to your own moves

Chessolve now notices a submitted move immediately instead of waiting for the server to echo it back.
The previous suggestion and arrow are cleared as soon as you play, preventing advice for a position that has already changed.
A short pending window keeps analysis from starting while the board and server are still catching up with the submitted move.
Premoves and quickly played moves remain protected from stale position updates.
The pending state ends as soon as the board or the confirmed game stream reaches the submitted position.

🔎 Safer game review and variation analysis

Moving backward and forward through a finished game now follows the position actually displayed on the board, even when Chess.com's move list is temporarily unavailable.
The starting position and earlier moves are recognized correctly instead of being confused with the latest live position.
Analysis variations that were never played in the game are treated as their own positions, so Chessolve can analyse the line currently shown on the board.
Turn detection for these side lines comes from the displayed position rather than an unrelated review clock.
Rapid board changes are allowed to settle before analysis begins, reducing incorrect results while Chess.com is still drawing a selected position or flipping the board.
Finished-game history can be recovered from Chess.com when the visible move list is incomplete.

Chessolve 6.6.0 makes live Chess.com analysis substantially more dependable. It follows confirmed game data when available, reacts immediately when you move, stays aligned during reviews and fast board transitions, and quietly returns to the proven fallback whenever the new source is not trustworthy.

CHESSOVLE 6.5.1:
Minor update with SEO nad Locales improvements

This changelog covers development from September 4 to September 17, 2026.
In total: 93 files changed, with 26,308 additions and 239 deletions.

• Added support for taketaketake.com — the third site Chessolve works on.
• Added best-move suggestions and evaluation for games played there.
• Added support for both live bot games and daily puzzles.
• Adapted to a board that is drawn rather than built from page elements.
• Followed the site's real game state instead of guessing from the board.
• Kept suggestions correct across rematches, new games, and game changes.
• Correctly identified who is playing which color, including bot games with no player name.
• Kept analysis aligned when the board moves, resizes, or sits next to page panels.
• Prevented stale suggestions from appearing after a move was already played.
• Fixed en passant positions being read incorrectly in some games.
• Added support for reviewing a game by stepping through its move list.

• Added analysis for taketaketake.com daily puzzles.
• Made puzzle analysis a Premium feature, with an upgrade button right on the best-move card.
• Added a “Puzzle solved” state to the best-move card.
• Applied a dedicated puzzle setup: fixed analysis depth, a single line, no auto-play, and no move-by-move review.
• Locked the corresponding analysis settings while solving a puzzle so they cannot be changed accidentally.
• Prevented an in-progress analysis result from appearing on a puzzle that has already been solved.
• Ensured the position only advances when the site itself confirms the move was accepted, and stays put otherwise.

• Added a highlight ring on the piece the suggestion recommends, inside the site's own promotion picker.
• Recognized the promotion picker opening and closing from normal pointer and keyboard use.
• Kept the extension display-only — you still promote by choosing the piece yourself.

• Added instant reaction to in-page navigation, so the panel switches immediately when you move between a game, a puzzle, and other pages.
• Removed the delay that previously made the panel lag behind the page by a second or more.
• Added the same instant navigation handling on Chess.com, Lichess, and TakeTakeTake.
• Reset analysis state cleanly when switching between games or screens.

*> Chessolve 6.5.0 brings full support for taketaketake.com — live games and daily puzzles — together with a clearer Premium puzzle experience, promotion guidance that stays out of your way, instant reaction to page navigation, and arrows that look native on every supported site.

🔥CHESSOLVE 6.4.1 Hotfix: CHESSCOM Rematch Detection

We fixed a critical issue where CHESSOLVE could remain stuck on “Waiting for board” after starting a new match or rematching the same opponent on CHESSCOM.

What happened?

Chess.com often keeps players on the same page between consecutive games. Chessolve correctly detected the new game, but two internal game identifiers became out of sync. As a result, valid board updates were rejected.

Chessolve 6.4.0: More Reliable Analysis Across CHESSCOM and LICHESS

This release focuses on making Chessolve more accurate and dependable when identifying your side of the board.

What’s new:
Player identity now remains stable when the board is flipped, resized, or remounted.
Improved support for authenticated and guest games on both adapters.
Guest sides can be safely identified from confirmed local moves when site account information is unavailable.
Analysis, autoplay, move review, ratings, evaluations, and player information now share one consistent view of who you are playing as.
Move arrows automatically redraw in the correct direction after flipping the board.
Stronger protection against stale data from previous games, detached boards, delayed engine responses, premoves, and rapid navigation.
Temporary or incomplete board positions no longer trigger analysis or incorrectly start a new game session.
Analysis and autoplay wait when your side cannot be identified confidently, preventing incorrect moves and unnecessary quota usage.
Player ratings and metadata are no longer inferred from board position, which fixes cases where opponent or bot information could be assigned to the local player.
For ambiguous guest games, Chessolve may wait until you make the first move manually instead of guessing your color.

Chessolve 6.3.0 brings more reliable analysis and a refreshed interface.
What’s new:
Analysis now uses complete PGN history for more accurate positions, repetitions, castling, promotions, and navigation.
Improved Chess.com handling for premoves, dragging, Undo, and move-history updates.
Stronger Lichess synchronization, including lobby-to-game navigation and round recovery.
Added Komodo 14.1 support with configurable Play styles.
Redesigned activity cards and icon-based navigation.
Added a tutorial for minimized mode.
Improved localization, accessibility, testing, and payment timeout handling.
This release focuses on ensuring Chessolve always analyzes the correct game position.

CHESSOLVE 6.0.1 is out:

What’s new:
Added a new Home activity summary showing:Current best-move streak, total requests for the current year and monthly activity chart

Activity statistics now refresh immediately after successful requests without resetting scroll position or rebuilding the entire screen.

Added localized, plural-aware activity labels for English, Spanish, Brazilian Portuguese, and Russian.
Best-move cards now explicitly display “Stockfish, depth X” instead of the generic depth label.

Improvements and fixes:

Improved accessibility with semantic metrics, descriptive chart labels, and dedicated synchronization attributes.

Prevented quota countdown ticks from unnecessarily rerendering the panel when countdown markup is unavailable.

Prevented stray text nodes from accumulating during screen transitions.

Refined Home and Profile card padding, activity-chart spacing, overflow handling, and light/dark theme presentation.

Expanded automated coverage for activity calculations, localization, live refresh behavior, quota countdowns, screen transitions, and UI fidelity.
