Owing to an omission in the Evergreen Release 3.10.1 source code package, a new download has been prepared. The new download includes the database upgrade script to go from Evergreen version 3.9.1 to version 3.10.0 that was missing from the previous download package.
The revised download is available on the Evergreen downloads page.
The Evergreen Release Team apologizes for any inconvenience this oversight may have caused and would like to thank Linda Jansova for bringing the omission to our attention.
