News/GBrowse Version 2.40 Released
GBrowse version 2.40 is now available for downloading from SourceForge and CPAN.
Here is the recent changelog:
- 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.
