CORE is a web-based, cloud software solution and so you are always going to be on the latest version. We do the software updates automatically in the background on a regular basis and announce it to our users via the CORE Community forum announcements or email every few weeks (typically biweekly). While logging in to CORE, you can click on the Update Log link at the bottom to read the release notes that list the features added and improvements made to CORE since the last update. Sprints are released on the testing environment for internal testing and after the QAC approval, the sprint is released to production.
