If you are someone who currently merges code into the 1.17wmf1 branch,
this mail is for you:
We need you to make sure that you merge your code into the 1.18wmf1
branch as well. That also means if you're deploying code and using
syncfile to push individual files, you need to push from both the
1.17wmf1 branch and the 1.18wmf1 branch. If you don't, your code may
not make it into the 1.18wmf1 branch.
