Reader Experiments: Deploy extension to English Wikipedia
Closed, ResolvedPublic2 Estimated Story Points

Description

NOTE: Week of Oct 20

The extension is now on Beta and has passed a provisional security review (a full review by the security team will probably happen next month).

Now we need to enable the feature on production (still hidden behind a URL param feature flag until we actually begin the A/B test).

Deploy to English Wikipedia.

Look at https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1189288 for reference.

We need to change the value from false to true for enwiki.
