# How many Helm release revisions does helm-controller keep for a HelmRelease that doesn't set maxHistory?

Flux CD, Hard (Expert), Architecture. https://k8wiz.com/uquiz/how-many-helm-release-revisions-does-helm-controller-keep-for-a-helmrelease-that-doesnt-set-maxhistory

- A. 10
- B. 1
- C. No limit
- D. 5

**Answer:** 5

**Explanation:** helm-controller keeps 5 revisions by default, half of the Helm CLI's default of 10. Older revision Secrets are removed after each upgrade. Setting maxHistory: 0 keeps every revision, which the Flux docs advise against for performance reasons.
