Highlight of the month
Wikipedias can now setup a mentorship program in an easy way.

Recent changes

 * The Growth team considers to stop control groups on all features. At few wikis, 20% of new accounts don't get the Growth features when they create their account. There 20% were used as control groups in order to know if the Growth features were changing newcomers' behavior. As our observations haven't showed a negative impact, and as we want to provide the same onboarding experience at all Wikipedias, we have decided to remove our control groups. We keep control groups on specific tools.
 * The quality score for Add a link has been changed. We will suggest less links for an article, but they will be more accurate.

News for mentors

 * All Wikipedias can now setup a mentorship program in an easy way.

Deployments

 * Add a link has been deployed to a 5th round of wikis.
