How to Release this Repo

Determine the current release version with git tag -l. It should look
something like vX.Y.Z. We'll call the current
version $CV and the new version $NV.
On master, run git log $CV.. to list all the changes since the last
release.
Edit the News section of README.md to include a summary of the changes.
Mail the CL containing the README.md changes. When the CL is approved, submit it.
Without submitting any other CLs:
a. Switch to master.
b. Tag the repo with the next version: git tag $NV.
c. Push the tag: git push origin $NV.
