svn commit
Check that only the sources, pom, checksums (md5, sha1), and signatures (asc) are added.
Log the commit with the release number "X.Y.Z-incubating-RCW" (substitute X.Y.Z and W for valid version and RC numbers).
Vote:
First, start a vote on the dev@ mailing list.
Once the vote has passed, forward the results of the vote to the general@incubator mailing list.
Once this second vote has also passed, you can promote the RC to a release.
Upload the artifacts to https://dist.apache.org/repos/dist/release/incubator/ via svn (note the difference: the release goes under the /release branch, the RC artifacts under the /dev branch).
Optionally deploy commodity binary packages via https://repository.apache.org
