During today's train deployment for 1.37.0-wmf.23,  we discovered a couple of blocking issues which resulted in rolling back to group 0.

Here they are in all of their glory:

1. T291128 Wikimedia\Rdbms\DBQueryError: Error 1146: Table 'arbcom_dewiki.echo_push_subscription' doesn't exist

2. T291124 PHP Notice: Undefined index: format

Hello,

Those issues have been promptly fixed and patches have been deployed. I will promote group 1 wikis to 1.37.0-wmf.23 at 13:00 UTC / 15:00 CEST.
