Walkthrough

A constant defining the maximum number of Helm release history entries to retain was added. The InitConfig function in the Helm chart package was updated to set this maximum history value to 10 when initializing the Helm action configuration.

Changes

Cohort / File(s)	Change Summary
Helm Release History Limiting pkg/helm/chart.go	Added maxReleasesToKeep constant (set to 10); updated InitConfig to set MaxHistory to this value after configuration initialization.

Poem

A hop and a skip in the Helm chart's den,
Now only ten releases—again and again!
With history trimmed, the clutter is gone,
The rabbit rejoices, the code hops on.

pkg/helm/chart.go (2)

18-18: LGTM! Well-chosen constant value.

The constant is appropriately named and the value of 10 provides a good balance between maintaining sufficient release history for rollbacks while preventing unbounded storage growth.

---

53-53: LGTM! Proper implementation of release history pruning.

The assignment correctly sets the maximum history limit after configuration initialization. This will effectively prevent accumulation of old release versions while maintaining enough history for rollback operations.
