Added

• Added various SSH task-running helpers such as Rocketeer::task(taskname, task)
• Rocketeer now has a copy strategy that copies the previous release instead of cloning a new one on deploy
• Composer execution is now configurable via a callback
• Added an option to disable recursive git clone (submodules)
• Releases are now sorted by date when printed out in rollback and current

Fixed

• Fixed a bug when running Setup would cancel the --stage option
• Fixed a bug where contextual options weren't properly merged with default ones
