Questions for the group

 * Deployments/releases
 * Should we aspire to a faster cycle than once every 2 weeks?
 * How active of a role should we play in support of non-Wikimedia uses of MediaWiki?
 * Test infrastructure
 * What role should beta play in the deployment cycle?
 * Do we make people deploy to beta before production, period?
 * Code review
 * What statistics should we track, and how should we go about getting those numbers?
 * Talk to Max, he started making some reports using the new REST API
