I've researched this in the new global Google Search tool
http://galaxy.psu.edu/search/web/ but didn't see the answer I
Is there actually a single "version" of Galaxy ? or is it a collection
components with their own versions ?
Can that can be seen on or near the Main front page ? I can't see a
Version/About type of item, either in menus or lurking in some rev
the bottom of pages etc.
Galaxy does not have versions as you'd find in commercial products.
There is a strict requirement that Galaxy provide reproducible
behavior always, so any new feature introduced into Galaxy (or any
enhancement to an existing feature) must not break any older feature
that came before. Because of this, you can always think of Galaxy as
being "version 1" if it helps.
Galaxy does, however have different distributed "builds" or mercurial
"changeset revision" numbers. You can find out what build your own
local instance is running if you type "hg heads" in the Galaxy install
directory of your local Galaxy instance. The build of the main public
Galaxy instance is included in the following string on the main page
in the center panel.
Galaxy build: $Rev 6299:b258de1e6cea$
The various builds that are made available in the distribution are
always documented in each of the associated news briefs that announce
whats availabe in each new distribution. See our wiki at
