This is the release of version 4.7.2 of the Authoritative Server.
Just one day after releasing version 4.7.1, we realised an important fix was missing from it. Specifically, AXFR clients (secondaries) can get very busy checking for updates on primaries, or could miss updates entirely. 4.7.2 fixes this.
A full list of changes can be found in the changelog.
Please make sure to read the Upgrade Notes before upgrading.
