With I89de0279ab52c3fa5367c0bb3e60853c3281b791, all changes that match mediawiki/.* are now sent to -dev. This means that extensions which were previously sent only to another channel, will now show up in other channels.
Version: unspecified
Severity: normal
Note, several repos were already crossposted to #wikimedia-dev + other specific channel(s). There's no clear boundary between wanted and unwanted behaviour, AFAICS; it may even be ok like this.
