Since we are in the middle of the process of branching I am creating this thread and marking it as a wiki for easily accessible release notes. Feel free to edit.
- Administer - Settings - Provisioning - DNS conflict timeout has been changed from integer to array of values (separated by comma). It used to represent timeout (in seconds) for DNS lookup attempts (dns_lookup macro and DNS record conflict validations). Multiple values in the array now represent multiple attempts to resolve name over DNS with the default value of [5, 10, 15, 20].
