Item Frame Cache for Maps

Item Frame Cache 1.5.0

New

• Added persistent map caching for multiplayer servers.
• Map pixel data is now stored locally and can be restored when the server no longer provides it.
• Cached map data can survive disconnects and game restarts.
• Added automatic detection and removal of corrupted cache files.
• Added automatic cleanup of old cached map data.

Performance

• Significantly reduced RAM usage for very large map walls and map floors.
• Reduced frame-cache bookkeeping overhead for large displays.
• Added optimized memory management using LRU and soft references.
• Map data is read and written asynchronously to minimize impact on game performance.

Reliability

• Server-provided map data always takes priority over locally cached data.
• Item frame positions remain session-only to prevent stale or ghost maps after reconnecting.
• Improved cache isolation when switching between servers.

Compatibility

• Fully client-side.
• No Fabric API required.
• Compatible with Minecraft 1.21.9, 1.21.10 and 1.21.11.
