diff: @@ -12,6 +12,8 @@ To actually perform the release, the core steps are:
  - Run the `release.yml` workflow on GitHub Actions
  - Wait for workflow to complete successfully and apply `vX.Y.Z` tag to git
  - Publish any crates `fluvio` client depends on, followed by `fluvio` crate itself
  +- Publish any updates to `fluvio-smartstream` if needed
  +- Update `infinyon/fluvio-smartstream-template` if needed
  - Fast-forward `stable` branch to match `master` (may become automated)
  - Push new commit with updated `VERSION` and `CHANGELOG.md` files
