Caution

Please note that due to incompatibilities in our previous releases, they can't be updated in place, even with a manual ALTER EXTENSION UPDATE query or other means. A new clean installation into an empty data directory/volume is required. All data should be backed up with mongodump/mongoexport before and restored with mongorestore/mongoimport after.

We expect future updates to be much smoother.
