Core: Release Calendar
The release schedule for sunpy is detailed in SEP-9 - this wiki page contains concrete dates for past and future releases and feature freeze dates.
Releases are scheduled for the first Friday in the month set by SEP-9, and feature freezes are two weeks prior to the release date.
