FCOS releases normally happen every 2 weeks. In addition, there may be asynchronous releases for e.g. CVEs or bug fixes.
For more details, see the design doc.
There are 3 primary streams: stable, testing, and
next. The next stream either tracks testing or the
next major version of Fedora. Content in testing is
promoted to stable after 2 weeks.
For more details, see the design doc.
FCOS versions are of the form X.Y.Z.A, where X is the
Fedora major version, Y is the date of the Fedora RPM
snapshot, Z is a stream identifier, and A is a revision
number.
Since stable releases are promoted from testing, their
Y dates will usually be 2 weeks behind testing.
For more details, see the design doc.
The release schedule and release owners are tracked in a HackMD document.
