 ## Known Limitations
 
-1. If one pushes an update to the `workspace.package.version` in the top-level `Cargo.toml` file without creating a pull request, the Release Checker workflow will not run. Hence, the release assets will not be automatically built and uploaded.
-
-## Possible Improvements
-
-1. Add a check to the [Releaser](.github/workflows/release.yml) workflow to ensure that the created/published release contains the expected assets. If it does not, create them and run the [upload-release-assets.sh](scripts/upload-release-assets.sh) script to upload the missing assets.
+1. Unless triggered manually, release assets will only be built after merging the release PR.
