A bugfix and stability release on top of v0.60.0, plus an experimental Linux Flatpak build. (v0.60.1 was withdrawn before promotion: a packaging bug crashed the app on launch. v0.60.2 is the same set of fixes with that resolved.)

Fixed

• Nihon Ki-in and other legacy-encoded SGF files (Shift-JIS, EUC-KR, GB18030, Big5, windows-1251) now open even without a CA[] charset property, instead of failing as unreadable (#1029).
• Engines wrapped in a .bat/.cmd script launch again on Windows (#1037).
• Launching on Linux no longer shows a false "This file is unreadable" when the launcher injects flags (e.g. --no-sandbox) or renames the binary (#954).
• Resign now records the game result instead of just adding a pass (#915).
• An attached engine responds to a human pass instead of waiting for a manual "generate move" (#857).
• Turning on move numbers no longer hides SGF markup: triangles, squares, and labels stay on the board (#965).
• Editing a node with compressed AB/AW/AE point lists no longer corrupts them into comma-joined junk (#856).
• Ctrl+click adds the coordinate to the comment box in edit mode and keeps it on the next edit (#844).
• "Clean markup > Label" removes old-style L[] labels, not just LB[] (#881).
• The last-move indicator renders correctly again under custom themes that colour it via background (#904).
• Heatmap win-rate labels display on Linux without requiring a non-free Windows font package (#804).
• Stopping an engine mid-match no longer logs an uncaught "GTP engine output has stopped" error (#720).
• Dead-stone detection handles single-eye groups correctly (@sabaki/deadstones 2.2.0).

Added

• Experimental Linux Flatpak (beta). Published alongside the AppImage as a -beta artifact and looking for testers, since it hasn't been verified end-to-end yet. Engine spawning is routed through flatpak-spawn --host and file access is scoped to the home directory (#803).

Dependencies

• @sabaki/gtp 3.1.0, @sabaki/sgf 3.5.0, @sabaki/deadstones 2.2.0.
• webpack 5.108.4, tsx 4.23.0, remark-breaks 4.0.0, concurrently 10.0.3.

The first release in a while, and a big one. Alongside a handful of new features it modernizes the entire runtime — Sabaki now rides the current Electron and Node, so it's faster, more secure, and native on Apple Silicon — and picks up a proper automated test suite along the way. Huge thanks to everyone who contributed while things were quiet.

Platform & runtime

• Upgraded Electron from 13 all the way to 43, in steady one-major steps, so Sabaki now ships on a current Chromium and Node runtime with the accompanying performance, stability, and security improvements.
• Removed the deprecated @electron/remote dependency and moved main/renderer communication onto a proper IPC bridge (context menus, dialogs, theme management, and settings all go through IPC now).
• Modernized the Node toolchain (Node 24, mocha 11) and pinned the dev/CI Node version via .nvmrc to match the shipped Electron runtime.

Added

• Score-lead analysis graph — the analysis graph can now plot score lead in addition to win rate (thanks to @kevinsung, #828).
• Absolute vs. relative analysis display — the analysis heat map can show each candidate move's win rate / score lead as its cost relative to the best move (which then reads as 0), instead of the absolute value, from View → Analysis Metric or with Ctrl+Shift+V (thanks to @kevinsung, #1022, #843).
• Move-numbering options — number moves from the start of the game, the current variation, or the most recent hotspot (thanks to @kevinsung, #826).
• Editable territory in scoring/estimate mode — click empty points to manually override the estimated territory; overrides reset when you toggle a stone's life/death (thanks to @RobertChrist, #941).
• Node-specific "Add/View Comment" in the game-tree node menu, replacing the out-of-place global toggle that used to live there (thanks to @RobertChrist, #942, #940).
• More keyboard shortcuts — for variation editing (copy/cut/paste/shift/make-main), toggling good/bad move annotations, toggling the player to move, and showing the analysis graph (thanks to @MarcelGruenauer and @kevinsung, #1018, #1021).
• Downstream-variation navigation — step through downstream variations with Shift+Left / Shift+Right (thanks to @petermao, #773).
• Clearer help text in the "add engine" dialog, with concrete path and argument examples for non-technical users (thanks to @Chewt, #967, #756).
• Clean Markup now strips score lead (SBKS) alongside win rate.
• Added an "Always show game result" preference, surfacing the existing setting in the Preferences drawer (thanks to @MarcelGruenauer, #1036).
• Added the Sabaki Subtle theme to the theme directory (thanks to @RobertChrist).

Fixed

• Sabaki now quits on the first ⌘Q on macOS instead of leaving the process running in the background (#1035, #157), and Ctrl+Q now quits on Linux (thanks to @kevinsung, #1024).
• Settings reliability — every setting is now sent to the renderer at startup, fixing controls that could silently read as undefined; the Score and Autoplay preference controls work again (thanks to @kvwu, #1026); and a renderer setting shim was fixed (thanks to @TransientError, #1028).
• Score-lead graph hardening — stays visible at a score lead of 0, refreshes when you toggle the metric on an unanalysed node, and no longer chokes on non-numeric values.
• Hardened GTP analysis parsing — dialect-aware win-rate normalization and graceful skipping of malformed info segments.
• Fixed root-node branch numbering.
• Fixed theme uninstall (broken by a rimraf v6 bump).
• Fixed a false "file unreadable" error in development mode.
• Fixed a MaxListenersExceededWarning from settings-change listeners.
• Left/Right once again map to Previous/Next Variation (thanks to @petermao).

Developer & internal

• Added a Playwright end-to-end test suite for the Electron app (smoke, renderer, engine, and analysis flows), plus engine-integration tests driven by golden GTP transcripts, and wired E2E into CI (#998).
• Reformatted the codebase with Prettier 3 (with a .git-blame-ignore-revs so history stays readable) and upgraded @primer/octicons 9 → 19.
• Updated CI to Node 20 / actions v4.

Dependencies

• Numerous dependency updates via Dependabot, including security fixes (e.g. tar extraction-traversal CVEs), and bumps to electron-builder, iconv-lite, js-yaml, rimraf, concurrently, and others.
