+**The `daily-dev-bump` workflow is currently broken: [#8558](https://github.com/flutter/devtools/issues/8558). Until it's fixed, manually update the DevTools version for the next release and open a PR with the changes:**
+```shell
+dt update-version auto --type minor
+dt update-version auto --type dev
+```
+
+1. ~~Update the DevTools version for the next release:~~
    ```shell
    gh workflow run daily-dev-bump.yaml -f updateType=minor+dev
    ```
-   This will kick off a workflow that will automatically create a PR with a
-   `minor` + `dev` version bump. That PR should then be auto-submitted.
-2. Make sure that the release PR goes through without issue:
-   - See the workflow run [here](https://github.com/flutter/devtools/actions/workflows/daily-dev-bump.yaml)
-   - Go to https://github.com/flutter/devtools/pulls to see the pull request that
