Update instructions to use YYYY.WW.REV for release versions.

@@ -89,27 +89,14 @@ There are two stages, testing and deployment.
 
 1. **Update the -tools version**: Once the tests pass, update the `setup.py` version and create a tag in the -tools repository at the same SHA you identified earlier.
 
-   - Determine the next [semver](https://packaging.python.org/en/latest/specifications/version-specifiers/#version-specifiers) number as appropriate for the changes in this release. e.g. `1.1.4`
-   - Create a local version identifier, with the format `YYYY-MM-DD-A`, where `YYYY-MM-DD` represents release date, and `-A` is used for the first release of the day (followed by `-B`, `-C`, etc., for subsequent same-day releases). e.g. `2024-08-24-A`
+  - Determine the next [stamp](https://blog.aspect.build/versioning-releases-from-a-monorepo) (which is valid [semver](https://packaging.python.org/en/latest/specifications/version-specifiers/#version-specifiers)) number as appropriate for the changes in this release. e.g. `2024.40.2`.
+  - Run `stamp.sh` to automatically perform this action. Use `--release` to additionally create a tag and push to main.
 
-     - Here is a command line script to generate the local identifier, tested on Mac:
-
-     ```
-     TAG_NAME=$(date +%Y-%m-%d)-A && \
-       SHA=$(git rev-parse HEAD) && \
-       git tag -a "$TAG_NAME" "$SHA" -m "Release $TAG_NAME" && \
-       git push origin "$TAG_NAME"
-     ```
-
-   - The new version will be `{NEXT_SEMVER}+{LOCAL_VERSION}`, e.g. `1.1.4+2024-08-24-A`
-     - **Update `setup.py` with this version.**
-   - Create a tag at the SHA from the testing phase, using the local version identifier.
