All, As Node 10 is EOL, many of our upstream tools have been dropping Node 10 support recently, which is slowing down development and creating work for teams. I have thus created the Node 12 CI infrastructure (T284343 <https://phabricator.wikimedia.org/T284343>) based on Debian Bullseye (thank you, SRE Service Ops!) and have today migrated almost all jobs over to use them (T284345 <https://phabricator.wikimedia.org/T284345>). There are a small handful of jobs (for Kartotherian, OOUI, and WikiPEG) that need further infrastructure work, and have not yet been migrated. I've submitted a few commits switching repos with .nvmrc files over to the new version installed in CI. This should be an uneventful change; I've spot-checked a few dozen repos and not found any issues. If there are any, please shout on the task or in #wikimedia-releng on Libera.Chat so I can fix it. Note: This only applies to the centrally-managed legacy CI jobs. If your repo is using the modern pipeline, you will need to wait for there to be an appropriate base image, which is tracked in T284346 <https://phabricator.wikimedia.org/T284346>. J. -- *James D.
