Changes/Fixes:

• Complete migration from JSON to SQLite database for all storage operations
• Eliminated hybrid JSON/database architecture causing data loss
• Commands now query database instead of in-memory JSON (this fixed a massive memory leak)

All in all this is a MASSIVE update in terms of performance. Note that previous logs created by older versions will not be compatible with this new version.

Additions

• New /minetracer saves command - Save monitoring for TPS analysis

Fixes

• Fixed drag operation logging bug. No more missing logs for container drag operations
• Enhanced backup system with atomic saves meaning less risk of data loss in the case of a server crash

Fixes

• Fixed a bug where rapid container interactions were being dropped and not logged
• Container logging now captures ALL interactions regardless of timing, ensuring no missing deposits or withdrawals
• Now properly detects and logs all types of item transfers, including single-click moves and drag operations
• Transfer detection is now more reliable and doesn't require perfect item count matching
• Improved sign placement logging to handle timing edge cases where blocks might appear as "air" during placement
• Improved data persistence with more frequent incremental saves (every 30 seconds instead of 2 minutes)
• Improved background processing maintains zero lag impact while increasing accuracy

Additions:

• Logs when players pick up items from the ground
• Logs when players drop items (Q key or drag outside inventory)

Changelog

Additions:

• Added command /minetracer undo to undo the latest rollback with a 20 minute save period
• Added 3 correlating commands

• /minetracer rollback <args> #preview command lets you preview the rollback for the executor only, without other players seeing it.
• /minetracer confirm confirms the rollback that is currently being previewed
• /minetracer cancel cancels the rollback that is currently being previewed

Changelog

Additions:

• KillEventListener now filters out irrelevant events early

Fixes:

• Deferred invalidation reduces frequency of expensive cache operations
• Background cache operations don't block main server thread

Changelog

Additions:

• Integrated kill event tracking with async spatial indexing using ServerEntityCombatEvents

Fixes:

• Fixed 544+ compilation errors by migrating all LogStorage references to OptimizedLogStorage

• Resolved container event filtering to properly capture QUICK_MOVE actions in MixinScreenHandler

MineTracer Changelog

[1.3.1]

Added

• Log entries now have a rolledBack flag to prevent double rollbacks and mark rolled-back actions.
• Lookup results now show rolled-back actions with strikethrough and gray color for clear visual feedback.

Changed

• Rollback command logic updated to skip already rolled-back actions and mark actions as rolled back after a successful rollback.

Fixed

• Prevented double rollback of the same action.

Changelog:

• Added minetracer$hasRelevantSlots flag to skip tracking entirely when no items are present
• Ultra-fast early exit if no container slots have items
• Quick container vs player inventory detection

• Pre-sized HashMap with typical chest size (27 slots) to avoid resizing
• Only store non-empty ItemStacks (most container slots are empty most of the time)
• Clear tracking map immediately after use to free memory

• Cache container position once per interaction instead of looking it up for each slot
• Skip empty-to-empty slot transitions entirely (most common case)
• Batch process only changed slots

• Only track container slots, never player inventory slots
• Skip processing if no relevant slots contain items
• Single pass through slots instead of multiple iterations

Changelog:

• Fixed issue where lookups returned empty results immediately after server start
• Fixed player name matching to be case-insensitive across all search methods
• Implemented proper global search for user+time queries without range restrictions

Changelog:

• The global search uses direct player indexing, so you can now lookup any player who has ever performed actions, whether they're online, offline, or anywhere in the world.

Change log:

• Removed unused command /flowframe rollbackpage

This update adds loads of optimization changes, including:

• Intervals scales efficiently with large datasets and high player counts
• Zero main thread blocking for all logging operations

Initial release. First public version of MineTracer with full block, container, sign, and kill logging, advanced lookup, rollback, and inspector features.
