Update changelog for helm-op release 0.2.1
+## 0.2.1 (2018-09-17)
+
+This is a patch release that allows helm-op to recover from a failed release install.
+If a chart is broken, Tiller will reserve the name and mark the release as failed.
+If at a later time the chart is fixed, helm-op can't install it anymore because the release name is in use.
+Purging the release after each failed install allows helm-op to keep retrying the install.
