What Is a Helm Release?
A Helm release is an instance of a chart deployed into a cluster under a unique name. Helm records each release with a revision history, so an upgrade produces a new revision and a rollback returns to a prior one. The release groups all the rendered Kubernetes objects from the chart into a single managed unit.
Why it matters
Treating an application as one named release makes installs, upgrades, and rollbacks atomic and auditable. Revision history gives a fast escape hatch when an upgrade misbehaves.
