Release notes

v1.1.0 Latest 2026-09-05
### Scouting a player - Profile reports now open with an "at a glance" strip — accuracy by phase, the tactical/positional mix of your mistakes, and where the points went — drawn from the same numbers the write-up below it is arguing from, so the two can never disagree. - Fixed phase accuracy on profile reports: it was averaged across every analyzed game instead of only the games that actually reached that phase, which understated the endgame for players whose games often end early. ### Analysis - The move list marks a position where the engine found no real alternative — nothing else held, so the played move gets no credit or blame for being "the only move." ### Interface - The header collapses onto phones better: What's New, GitHub, and the account menu now live behind one menu button instead of competing with Scout and Load game for space. - "Your recent games" shows a loading indicator instead of a blank gap while it fetches from Lichess/Chess.com. - Fixed a mobile layout bug where a long opponent name or opening line could push the landing page's cards past the edge of the screen instead of truncating inside them.
v1.0.0 2026-08-29
First tagged release. ### Analysis - Step through any game with Stockfish evaluation on every position, an eval bar, engine lines, and an evaluation graph you can click to jump. - Move-quality grades (`!!` through `??`) computed from the engine and tactics rather than read out of the PGN, shown on the board and in the move list. - AI commentary that explains each position in plain English, grounded in the same engine numbers shown on screen. - Ask follow-up questions about the loaded game in the chat panel. ### Getting games in - Upload or paste a PGN, or pick a recent game straight from Lichess or Chess.com. - "Scout a player" builds a whole-account report from an opponent's recent games, with evidence links back to the exact move. ### Interface - Drag-and-resize desktop dashboard; your layout persists between visits. - Mobile three-detent drawer with reorderable tabs. - Share links reopen a game at the exact ply. - Sign-in now returns you to where you were instead of the landing page.
