A previous version of the CRUD spec said that the driver should only raise errors when the hint option is provided to an unacknowledged write against a server that does not support the hint option. However, the CRUD spec also says that the driver should raise errors whenever the arrayFilters or collation options are provided on any unacknowledged write. The spec has been changed to state that the driver should raise an error when the hint option is provided on unacknowledged writes against any server version.
