When you commit or find a revision post-r77974 that you feel should be in 1.17 (bugfixes, typically, no new features), tag it with "1.17" in CodeReview.
It's been pointed out on IRC that you need to be in the coder group on mediawiki.org to be able to do this. If you're not in that group but are a committer or otherwise well-known and in good standing, just ask for it. Anyone who's already a coder can promote others (it's viral!).
