BetterReplay

[Unreleased]

Added

• Frame-by-frame step controls during paused replay; step backward or forward one tick at a time via ⏮/⏭ inventory buttons (slots 6–7)
• Variable playback speed controls during active replay; adjust with ⏪ Slower/⏩ Faster inventory buttons (slots 6–7) using configurable step increments
• Current playback speed displayed in the action bar as [X.Xx] during playback
• New config keys Playback.Speed-Step (default 0.2) and Playback.Max-Speed (default 1.0) to control speed increment and upper bound
• Finalized binary .br replay storage for file and MySQL backends, including crash-safe append-log recording, lazy indexed loading, preserved recording start timestamps, startup recovery of orphaned temp logs, filtered export tooling, hidden benchmark/debug utilities, and temporary legacy JSON compatibility during migration
• Replay protection commands and metadata, protected replay highlighting in /replay list, and config-driven retention cleanup with duration parsing
• Optional chunk baseline capture and chunk-aware playback for binary replays, including block-entity support, replay chunk caching, Playback.Chunk-View-Radius, Playback.Chunk-Send-Limit-Per-Tick, Playback.Chunk-Clear-Limit-Per-Tick, Playback.Chunk-Timing-Diagnostics, and Playback.Chunk-Mode

Fixed

• activeSessions in RecorderManager changed to ConcurrentHashMap to prevent ConcurrentModificationException (#33)
• PacketEvents block-break recording is now rescheduled onto the server thread to avoid Netty-thread contention and unsafe shared-state mutation (#43)
• Held-item swaps and hotbar slot changes are now captured immediately for more accurate replay inventory playback
• Nested replay inventory loss when starting a replay during an active replay (#31)
• Replay controls getting stuck after replay ends (#27)
• Replay export now writes under the plugin data folder
• Chunk playback restore flow now handles unload timing and viewer return cases more reliably
• Replay chunk load probing now frees completed missing-chunk checks before scheduling the next async wave, so higher chunk send limits are not throttled by one-tick queue lag when many surrounding chunks were never recorded
• Replay chunk load probing now runs at 10x the configured chunk send rate, so fast missing-replay-chunk checks do not throttle how quickly the viewer can discover whether nearby chunks were actually recorded
• Config migration now preserves wrapped pseudo-comments, keeps the managed header stable, and avoids accumulating blank lines between root sections

Changed

• RecordingStopEvent now fires synchronously to fix async AntiCheatReplay compatibility
• ReplayManager now exposes listSavedReplaySummaries, protectSavedReplay, unprotectSavedReplay, and returns ReplayDeleteResult from deleteSavedReplay
• Config settings ownership moved out of Replay into a dedicated typed, comment-preserving config manager with versioned migrations
• Replay sessions now always start at 1.0x speed; Playback.Max-Speed is enforced to a minimum of 1.0
• Config keys for list settings were renamed from list-page-size/list-protected-highlight-color to List.Page-Size/List.Protected-Highlight-Color; values are auto-migrated on startup
• Update checks now treat -SNAPSHOT builds as their corresponding release, and Modrinth publishing metadata now includes Purpur, Spigot, and Bukkit loaders
• Modrinth uploads now publish the matching release changelog on main and the [Unreleased] section for dev alpha builds
