Here is the recent changelog:

    2.40
      * Quash a few uninitialized variable warnings when bringing up track configuration dialog.
      * Fix inability to toggle visibility & favorite status of plugin tracks from the track titlebar.
      * Added caching of inverted configuration file data structure to speed up track rendering on really huge configuration files with many stanzas. Cache structure is stored in /tmp/bio_graphics_ff_cache_$UID
      * Add ability to save and restore named snapshots of current state.
      * Changed behavior of render slave to a prefork model. Activate by including PREFORK=5 (or other desired number of servers) in /etc/default/gbrowse-slave.
      * Added support script for Amazon cloud image: gbrowse_attach_slaves.pl creates slave instances for AMI ami-c6ca31af.
      * Change default tmpfile location to /var/tmp/gbrowse2 (was /tmp/gbrowse2).


The most significant change is actually the third from the top, which improves speed dramatically when used with data sources that have lots of complex track definitions.
