Versions and channels

The charm follows the major version of Apache Superset: each Charmhub track carries one Superset major series, and each risk level within a track carries a release stage.

Track	Superset series
6	Superset 6
5	Superset 5
latest	Development builds from the main branch; not tied to a series

Deploy from a versioned track to pin a major version:

juju deploy superset-k8s --channel 6/stable

Upgrading between major stable tracks is a supported, non-breaking operation:

juju refresh superset-k8s --channel 6/stable

Charm and workload compatibility

The workload image is attached to the charm revision as the superset-image resource, so deploying from any */stable channel gives a matching charm and workload pair. Pinning a revision by hand is only necessary in the rare case of reproducing an older deployment:

juju deploy superset-k8s --channel latest/stable --revision <REVISION> --resource superset-image=<RESOURCE_REVISION>

Charmhub’s releases page lists which resource revision belongs to each charm revision.

Branches and channels

Development follows one branch per track in the charm repository:

Branch	Channel
main	latest/edge
track/<N>	<N>/edge

Releases are promoted from <N>/edge to <N>/stable after validation.
