Upgrade from 1.5 to 1.6

Aggregation builder

  • Fixes a BC break when converting expression objects in the Doctrine\MongoDB\Aggregation\Expr class.
  • Adds extension points to customize expression conversion in the following stages:
    • $bucket
    • $bucketAuto
    • $graphLookup
    • $replaceRoot

Version support

  • Support for MongoDB server versions below 3.0 has been dropped. These are no longer supported by MongoDB. We recommend you upgrade to a recent version
  • The 1.5 version of the legacy driver is no longer supported. This library now requires at least version 1.6.7 of the legacy driver.
  • PHP 7.2 is also supported using mongo-php-adapter
