Change Log

Mirror is published to the Asset Store at the start of every month, unless some critical issue causes a delay.

Mirror uses semantic versioning, and the versions shown here are those that were published to the Asset Store, and occasionally major version bumps happen mid-month between store submissions and are therefore not individually shown here.
