A short explanation of the proposed change:
Implement stack lifecycle management with ACTIVE, DEPRECATED, RESTRICTED, and DISABLED states to enable gradual stack deprecation without causing application downtime.
An explanation of the use cases your change solves
Implement the Stack Management RFC by adding a
statefield to stacks with four lifecycle states: ACTIVE, DEPRECATED, RESTRICTED, and DISABLED. This enables operators to gracefully phase out stacks through lifecycle restrictions rather than causing immediate app downtimeLinks to any other associated PRs
This PR implements RFC #0045.
While the
RESTRICTEDstate is not explicitly defined in the RFC, it is functionally identical toLOCKED. We chose the termRESTRICTEDto prevent any confusion with the existing 'Locked' state used in Buildpacks.I have reviewed the contributing guide
