During this period, it's best to avoid massive changes (refactoring, code cleanups, re-indenting. etc.) on trunk because it makes merging more difficult.
If you want/need to do, please also do the merges.
which means there should be no indentation, refactoring, tests or experiments in the stable branch.
So, could we please all try, for about a month only, to commit "Fixes only" in 17.x (which includes translation improvements). The aim is to reduce risk caused by commits that do not have an obvious and direct benefit to the release and
cause noise which makes everything harder to monitor.
If this is not clear please update the documentation on dev so that it is.
