GA means "General Availability". It's major release, with no new features, only bugfixes. It's intended to be used in production environments, and is a hence a stable version.
if you made a backup of your workspace before upgrading -- Then you can import the jobs from your backup into a 4.1.2 installation. If you didn't make a backup, take this as a lesson
