User confusion re: MongoDB compatibility policy for pre-100 tools releases. Not sure what the best way of clarifying this in the docs would be.
From the linked support request, it appears there is an incompatibility between mongodump version 4.2 and MongoDB 3.4.22.
The error as reported by the customer is:
The command which triggered this error was:
Use version 4.0.x of the mongodump.
- Please verify if this is a bug, or a known incompatibility.
- Please review the other tools in the 4.2 release to determine if there are other incompatibilities/bugs with supported previous versions of MongoDB.
- If this is a known incompatibility, or a fix is not planned, please open a documentation ticket to update our customer-facing documentation with the information.
