How this works

Any serious bugs affecting wmf.8 should be added as subtasks beneath this one.
- Use this form to create one.
Any open subtask(s) block the train from moving forward. This means no further deployments until the blockers are resolved.
If something is serious enough to warrant a rollback then you should bring it to the attention of deployers on the #wikimedia-operations IRC channel.
If you have a risky change in this week's train add a comment to this task using the Risky patch template
For more info about deployment blockers, see Holding the train.

With @mmodell as backup.

This train is a little odd due to Thanksgiving. It will go to group0 on Tuesday 2019-11-26, group1 on 2019-12-04 (the following Wednesday), and group2/all wikis on 2019-12-05 (the following Thursday).

Cutting branch using:

cd ~/release/make-release
./branch.py --core --core-bundle wmf_core --bundle wmf_branch --branchpoint HEAD --core-version 1.35.0-wmf.8  wmf/1.35.0-wmf.8

An update to this: Saw some odd behavior from branch.py, fell back to standard process.

Noting here that wmf.8 is deployed to all wikis. There's still logspam proceeding from T240248, but we've made a decision that keeping wmf.8 in production and hoping for / focusing on a resolution to those issues in wmf.10 is lower risk than rolling back to wmf.5 and proceeding directly from there to wmf.10.
