Hello, If you simply use the Galaxy Main or Test sites hosted at PSU, you can safely ignore this message. It pertains to people who've checked out their own copy of Galaxy for development or local use. Galaxy development has recently moved source control systems, from Subversion to Mercurial. This means that anyone using a local copy of Galaxy will need to make some changes to be able to download future updates. The preferred method of obtaining Galaxy source is through Mercurial directly (the 'hg' command): hg clone http://www.bx.psu.edu/hg/galaxy galaxy_dist Tarballs are also available via the zip/gz/bz2 links here: http://www.bx.psu.edu/hg And the repository is mirrored in Subversion here: svn co http://www.bx.psu.edu/svn/galaxy galaxy_dist Unfortunately, modifications to local copies of Galaxy will need to be transferred from your old checkout to the new checkout. Please let us know via <galaxy-bugs@bx.psu.edu> of any issues. Thanks, and thank you for using Galaxy. --nate
