Release Highlight

Clarify BSONVersionError message

Previously our BSONVersionError when thrown stated that the "bson type must be from 6.0 or later" our intention is to prevent cross major bson types from reaching the serialization logic as breaking changes to the types could lead to silent incompatibilities in the serialization process. We've updated the message to make that intention clear: "bson types must be from bson 6.x.x"
