 * "scap sync" will be renamed to "scap sync-world" in the next release. If you use "scap sync" non-interactively, please add a note to: https://phabricator.wikimedia.org/T250302 (and also, explain why you're using it)
 * scap sync now has option --canary-wait-time; https://phabricator.wikimedia.org/T217924

Incoming/Needs attention

 * Gergo is asking for feedback on dropping php7.2 in the next MW release (1.35):
 * https://lists.wikimedia.org/pipermail/wikitech-l/2020-July/093650.html
 * https://phabricator.wikimedia.org/T257879
 * Someone should reply with our take on the impact this decision has for CI
 * tl;dr: dropping it from 1.35, which is an LTS release, means we won't have to support php7.2 in CI for the next 3 years and instead would only need to support it for as long as we're using it in production.
 * TODO: Antoine to comment on the task
