### Release Notes

<details>
<summary>googleapis/google-cloud-go</summary>

### [`v0.62.0`](https://togithub.com/googleapis/google-cloud-go/blob/master/CHANGES.md#v0620)

[Compare Source](https://togithub.com/googleapis/google-cloud-go/compare/v0.61.0...v0.62.0)

##### Announcements

-   There was a breaking change to `cloud.google.com/go/dataproc/apiv1` that was
    merged in [this PR](https://togithub.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.
