Software Development Schedule

Software Release Checklist

GUNNS is in the maintenance phase, and the schedule is budget-driven. Minor releases (v17 .2 , etc.) are released roughly semi-annually.

We have no schedule for major releases (v 17 .0, etc.). A normally-scheduled minor release will instead be a major release when it contains significant architectural changes or new content.

See Release_Notes for documentation on past release schedule & content, and plans for the next future release.
