Highlights / Notes

The integrated webserver now pushes markers and freshly rendered tile-updates to connected webapps using SSE.
And some more fixes and smaller improvements.

Upgrading from 5.22

  • Replace the bluemap.jar-file with the new one
  • Delete your <webroot>/index.html to make bluemap update the webapp

Optionally:

  • Add the following lines to your webserver.conf:
    # Whether to use Server-Sent Events (SSE) for pushing tile and marker-updates to the connected clients.
    # Default is true
    sse-enabled: true
    
  • Add the following lines to your webapp.conf:
    # This will configure the webapp to request the map-tiles compressed and decompress them manually.
    # Enable this only if you intend to host the webapp statically, with an external webserver without additional configuration.
    # Default is "false"
    #client-decompression: true
    

Changelog since 5.22

  • Use Server-sent events to push updates for map-tiles, players, and markers (optional, thanks to @pR0Ps, #819)
  • Added webapp-option to decompress tiles on the client, making it possible to host the webapp statically (thanks to @fechan, #815)
  • No longer delete the whole map if no region-files exist (map might be configured incorrectly)
  • Try to resolve symlinks when loading resources
  • Added (usually hidden) config for dimension-type to fix paper-api added worlds
  • Removed native linear region format support, use the linear-addon instead
  • Track full-update-interval per-map instead of globally
  • Fixed race-condition when saving lowres-tiles sometimes corrupting them (#821)
  • Fixed live-player-markers config not being respected
  • Fixed worlds with / in dimension key not being detected correctly on paper
  • Fixed tasks sometimes not saving/loading correctly
  • Fixed in-memory region-update-timestamps not resetting on purge
