 # Changes
 
+## v0.62.0
+
+### Announcements
+
+- There was a breaking change to `cloud.google.com/go/dataproc/apiv1` that was
+  merged in [this PR](https://github.com/googleapis/google-cloud-go/pull/2606).
+  This fixed a broken API response for `DiagnoseCluster`. When polling on the
+  Long Running Operation(LRO), the API now returns
+  `(*dataprocpb.DiagnoseClusterResults, error)` whereas it only returned an
+  `error` before.
+
+### Changes
+
+- all:
+  - Updated all direct dependencies.
+  - Updated contributing guidelines to suggest allowing edits from maintainers.
+- billing/budgets:
+  - Start generating client for apiv1beta1.
+- functions:
+  - Start generating client for apiv1.
+- notebooks:
+  - Start generating client apiv1beta1.
+- profiler:
+  - update proftest to support parsing floating-point backoff durations.
+  - Fix the regexp used to parse backoff duration.
+- Various updates to autogenerated clients.
