Team Business

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
