GitHub announced the discontinuation of its old Subversion (SVN) support service, which will be shut down on July 31, urging users to switch to the improved Subversion Client Support introduced a year and a half ago. The older service, running on svn.github.com, will no longer be active, and users with SVN checkouts from this domain are advised to recreate them using the new GitHub URL format. The previous service only allowed checkouts of the default branch, usually 'master,' requiring users to update their checkout URLs to the new format that includes the trunk/branches/tags convention for better functionality and access.
