 Description   
  • The matcher will be given a $version number of 0 for MongoDB 3.6.
    • MatchExpression parsers must fail if $version exists and its value is not 0.
  • The catalog will store a $version field for partial filter expressions and document validation filters as appropriate:
    • If $version is 0, the $version field is never persisted. A missing $version field always implies version 0.
    • When $version 1 match expressions are introduced in a future version of MongoDB, the $version field will be persisted.
