v0.2.1-mc26.20

Changed

• Reworked export capture around the RenderDragon scene target and semantic world-submission detection instead of the swap-chain UI target and a draw-count threshold.
• Polished editor and replay-browser scrolling, timeline routing, selection feedback, icon alignment, compact controls, animations, and bilingual labels.
• Preserved the release tag during CI builds so packaged manifests carry the published version.
• Kept the configuration version and recording-file snapshot context version at 1; complete v0.2.0-mc26.20 archives remain compatible and require no conversion.

Removed

• Removed unreachable legacy clip, track, transition, clipboard, menu, hint-bar, curve-editor, and entity-render-hook code.
• Removed periodic camera, entity-pose, and graphics-capture diagnostics from normal rendering and export paths.

Fixed

• Fixed D3D12 exports capturing the UI composition target, which could produce uniform sky-color frames or include the export overlay instead of the world scene.
• Fixed sparse scenes stalling export when world submissions fell below an arbitrary draw-count threshold.
• Fixed the HBUI idle screen appearing in captures while Playback owned input.
• Fixed camera preview stepping backward when native render alpha and replay ticks advanced on different clocks, especially at reduced playback speeds.
• Fixed ordinary observer server synchronization abandoning a parked preview camera after pausing.
• Fixed replay-browser wheel scrolling and crowded timeline labels or click routing obscuring the intended target.

v0.2.0-mc26.10

August 20, 2026 Hotfix

This pre-release has been rebuilt from the updated v0.2.0-mc26.10 tag.

Multiplayer replay fixes

• Fixed replay terrain appearing as air on servers that send inline or cache-enabled chunk data.
• Preserved native request-mode chunk packets for local worlds while converting incompatible server chunk forms after client decoding.
• Fixed local-world seek failures caused by duplicate chunk columns or missing subchunk sections.
• Preserved actor-registry configuration across resource-pack handshakes so custom server entities can be reconstructed in newly recorded replays.
• Preferred the latest LevelChunk record when multiple versions of the same chunk column are present.

Video export fixes

• Kept offline video export rendering while Minecraft is unfocused and prevented pause or suspend UI from interrupting capture.
• Removed the fixed 5x5 camera-neighborhood readiness requirement that could leave valid exports stuck at frame 0.
• Export preparation continues to wait for replay tick, dimension transition, UI stability, and configured warm-up state.

Compatibility

• Replays recorded before this hotfix on affected servers may already be missing portable chunk or custom-entity registry data. Those archives cannot be repaired and must be recorded again.
• Complete v0.2.0-mc26.10 archives do not require conversion.
• Replay archives created by Playback releases before v0.2.0-mc26.10 remain incompatible and must be recorded again.
• The configuration version and recording-file snapshot context version remain 1; no migration layer is provided.

Original v0.2.0 highlights

• Added cinematic camera creation, keyframes, sequence binding, live preview, property editing, and undo/redo.
• Added Smooth, Linear, Ease In, Ease Out, Ease In/Out, Hold, Hermite, and Cubic Bezier interpolation.
• Added experimental H.264 MP4 and PNG-sequence export with D3D11/D3D12 capture, configurable frame rate, resolution, SSAA, and warm-up frames.
• Added dimension-aware camera segmentation and shared preview/export camera and entity-pose sampling.

Known limitations

• Video export does not include audio.
• Editor projects are currently in memory only and are not persisted between replay sessions.
• Playback cannot reconstruct chunks or server registry data that were never recorded.

v0.1.2-mc26.20

Breaking Changes

• Changed the replay metadata and snapshot stream to require per-chunk dimension/view context, explicit local-player creation, and forced snapshot boundaries. Replays created by v0.1.1 or earlier are not compatible and must be recorded again after upgrading.
• Kept the internal Config version field at its initial value (1) and left third-party dependency version declarations unchanged. No configuration or replay migration path is provided.

Added

• Added replay-browser search, playable/unavailable filters, five sorting modes, grid/details views, import, rename, multi-selection deletion, path copying, and File Explorer integration.
• Added replay thumbnail capture into icon.png and thumbnail display in the browser on both D3D11 and D3D12.
• Added in-memory editor groundwork for sequence and world-actor segment operations, camera-track data and keyframes, and undo/redo. Project persistence and video export remain unavailable.
• Added D3D11 rendering support for the native replay UI alongside the existing D3D12 path.

Changed

• Replaced the resource-pack-based replay browser with a native ImGui browser while retaining a lightweight resource-pack button on the main menu.
• Rebuilt the existing replay editor around resizable viewport, details, and timeline panels, zoomable tracks, viewport maximize/restore, and revised transport controls.
• Refactored replay snapshots to carry dimension context and local-player state explicitly, and to force snapshot playback at dimension boundaries.
• Unified command, replay-browser, and editor messages through the English and Simplified Chinese catalogs using LeviLamina's native translation path.
• Bundled the Lucide icon font directly with the mod and reduced the UI resource pack to its main-menu button, bilingual label, and required metadata.
• Consolidated the feature overview in the root README files and replaced the legacy documentation tree with focused installation and source-build guides.

Fixed

• Restored installed and standalone playback-ui.mcpack packaging so the main-menu button is available in complete mod installations and as a separate Release asset.
• Reworked cross-dimension recording and replay handling to close the source chunk at the tick boundary, wait for the target dimension, and apply a dimension-scoped forced snapshot.
• Prevented ordinary forward seeks from reloading snapshots and moving the viewer; snapshot reloads remain for backward seeks, dimension changes, and forced boundaries.
• Improved replay snapshot cleanup and chunk application by refreshing the replay player, isolating chunks by dimension, filtering unsuccessful subchunk responses, and clearing recorded objectives between snapshots.
• Expanded D3D12 command-queue and swap-chain capture to cover additional renderer creation paths.

v0.1.1-mc26.10

Changed

• Add .pdb to help diagnosis crashes.

Playback v0.1.0-alpha.2

Changed

• Bundled the Playback UI resource pack with the mod so LeviLauncher and Lip installations load it automatically through LeviLamina.
• Kept playback-ui.mcpack available as a standalone release asset for manual import.

Notes

• This release changes installation packaging only. The replay format and replay runtime behavior are unchanged from 0.1.0-alpha.1.

Playback v0.1.0-alpha.1

Added

• Client-side recording with asynchronous replay storage and export.
• Main-menu replay browser and isolated replay-world loading.
• Replay timeline controls for pause, seek, speed, and exit.
• Chunk snapshots, cached chunk replay, entity movement, and selected game-packet replay.
• English and Simplified Chinese localization for commands, the replay editor, and the resource-pack UI.

Notes

• This is the first public test release. Replay files and behavior may change before 1.0.0.
• Playback currently targets Windows x64 and the LeviLamina 26.10.* client runtime.
