0.5.0-beta.1

Added

• Silent background auto-update. MultiView now keeps itself — and other Zeffut Modrinth mods present in your mods/ folder — up to date automatically. On startup it hashes the local jars, asks Modrinth for the latest build matching your Minecraft version and loader, downloads verified updates, and swaps them in at game shutdown (a detached helper finishes the swap if a jar is still locked, e.g. on Windows). It runs entirely in the background. Opt-out with auto_update: false in config/multiview-telemetry.json or -Dautoupdate.enabled=false; scope it with the update_owner, update_all, and update_exclude settings.

Changed

• Multi-row selection replaces the per-replay checkboxes: left-click replay rows to build the merge set (selected rows are highlighted), double-click still opens a replay, and a single selection keeps Flashback's Open/Edit/Delete buttons working.
• Removed the first-run telemetry chat message. Telemetry stays anonymous and opt-out via /mv telemetry off (and -Dmultiview.telemetry=false).

Fixed

• The Merge button no longer overlaps Flashback's search/sort row and resizes responsively with the window.
• The Merge button is correctly greyed out when the selected replays are not from the same recording moment (derived from the immutable replay file name, not the file last-modified time) and for empty (0-tick) replays.

0.4.1-beta.1 — anonymous telemetry

Adds an anonymous, opt-out telemetry layer (PostHog, EU servers) so the mod can be improved based on real usage: merge metrics (counts, durations, sizes, outcomes, per-phase timings), feature/command/UI usage, runtime versions, and sanitized error reports. No player names/UUIDs, world/server names, file paths, or replay contents are ever sent — an anonymous random ID is used.

Disable any time with /mv telemetry off (or /mv telemetry status), the JVM flag -Dmultiview.telemetry=false, and it is auto-disabled in dev environments. See the README "Telemetry & privacy" section.

Fixed

• Cross-version first-run notice (chat API differs between MC 1.21.x and 26.1). All targets — 1.21.11, 1.21.9/1.21.10, 26.1 — build and pass the merge regression suite.

0.4.0-beta.1 — audit-driven beta

Multi-agent audit pass surfaced 35 findings across security, correctness, cross-version compatibility, and the merge algorithm itself. This beta closes the 2 CRITICAL and 10 HIGH-severity items. Marked as a beta until the deferred follow-ups land and the mod has more real-world validation.

Fixed — CRITICAL

• MoveEntities entity-id remap (the underlying cause of GitHub issue #1 for overlapping merges): the bulk-tick MoveEntities action is now decoded, every VarInt entityId is remapped through safeRemap, and the new bytes are re-emitted. Previously secondary sources' local ids collided with the primary's global namespace, producing the "frozen mobs / default rotations / missing equipment" symptoms.
• SET_ENTITY_LINK wire format: read/write int32 instead of VarInt (which mis-decoded any id above 127). Sentinel for "no holder" treated as <= 0 to cover both legacy (-1) and modern (0) encodings — leashes no longer randomly attach to the wrong entity.

Fixed — HIGH (security)

• Path traversal guard in FlashbackReader.open: every segment path is normalised and confined to the replay folder.
• Zip-bomb entry-count cap (65 536 entries per source) on top of the existing 5 GB byte cap.
• OverlapValidator refuses to probe replays whose first segment exceeds 256 MB (OOM guard).

Fixed — HIGH (correctness)

• PIU bulk re-emit no longer fires on mid-segment intercalation (5-arg overload bug closed).
• copyPrimarySnapshotForTick uses FileChannel.map instead of Files.readAllBytes, avoiding OOM on long replays.
• HURT_ANIMATION and PLAYER_COMBAT_KILL reclassified EGO → ENTITY so their entity id is remapped through the global namespace.

Fixed — HIGH (cross-version)

• fabric.mod.json java dependency is now templated: 1.21.x jars declare >= 21, the 26.1.x jar declares >= 25. Previously the 26.1 jar advertised >= 21 and crashed at classload on JDK 21 instead of failing cleanly via Fabric.
• addRenderableWidget reflection on 26.1+ iterates Screen.class.getDeclaredMethods() and binds to the first overload accepting our Button — resilient to method-rename churn.

Fixed — i18n

• English users no longer see French progress labels: MergeOrchestrator emits multiview.merge_progress.phase.* translation keys and the screen picks Component.translatable vs Component.literal based on the "multiview." prefix.

Deferred to follow-up

• EntityMerger UUID-overwrite race and safeRemap phantom-ID race (H8, H9) — real but carry regression risk; separate focused session.
• SOUND_ENTITY / LEVEL_EVENT remap (H7) — non-trivial wire format.
• MergeOrchestrator refactor (still ≥ 1300 lines).
