OpenSave 2.0.0 — the Go rewrite

OpenSave has been rewritten from the ground up in Go. The Electron app is gone: 2.0 is one small native binary with an embedded UI — faster to start, lighter on RAM, nothing to install but the app itself.

Your data comes with you. On first launch, 2.0 imports everything from the original app — tracked games, snapshots, pairings, and cloud settings (opensave-db.json is kept as a backup, never deleted). Old (1.x) and new (2.0) devices speak the same wire protocol, so a mixed fleet keeps syncing while you upgrade one machine at a time.

Highlights

• One native binary — Wails desktop app with a dark UI and system-tray background running; no Node, no Electron, no runtime.
• Auto-scan that actually finds things — Steam (real library folders), emulators (RetroArch, Dolphin, Ryujinx, Yuzu, Citra, PCSX2, RPCS3, PPSSPP, Cemu, Xenia), Goldberg/CODEX/RUNE-style repacks, Epic, GOG, Unity LocalLow, and Unreal saves — shown as a grid of cover-art tiles.
• Block-level delta sync — SHA-256, adaptive 64 KB–2 MB blocks; only changed blocks ever transfer.
• Snapshot history with branches — whole-save or single-file restore, an automatic safety snapshot before every restore, and branches for parallel playthroughs.
• Lineage-based conflict resolution — keep local, keep remote, or keep both as a branch. Detected by sync history, not wall clocks. Fully undoable.
• P2P everywhere — zero-config LAN discovery, or internet sync via relay room codes (self-hostable relay included).
• Cloud backup (optional) — Google Drive, Dropbox, OneDrive, WebDAV, webhook, or a local/NAS folder, with a browsable per-game cloud snapshot explorer.
• In-app updates — one-click install from GitHub releases, or pull a newer build directly from a paired device.
• Headless CLI — opensave-cli covers scan/add/status/snapshot/rollback/branch/checkout for servers and Steam Deck.

Reliability & safety

• Conflict resolution never overwrites a peer without consent; restores confirm first and snapshot the current state.
• Interrupted syncs auto-retry; leftover temp files are cleaned up and never propagate.
• Sync lineage only counts files verifiably present on both sides — a failed download can no longer delete the original.
• Antivirus file-lock races are retried instead of failing the sync.
• Periodic reconcile backstop guarantees cross-device changes are always detected.
• Activity log at ~/.opensave/opensave.log; clear full-screen errors (with Retry) instead of endless loading panels.
