cvs_deploy 5.x-1.0

Official stable release compatible with Update status version 5.x-2.0. Only a few minor bugs have been fixed since the 5.x-1.0-beta release:

• #162737: Fixed bug on modules page confirm form caused by blindly adding the human-readable version strings to the form, even if it's just the confirm form and there's no table of modules.
• #172458: Modified code to explicitly check for the 5.x-2.* versions of update_status functions we want, so cvs_deploy will gracefully degrade if update_status version 5.x-1.* is still in use.
