New Features

• New classification (knn-only) ref meta fields added (#1244)
  See #1244 for details. When using the _classification underscore prop, the ref meta, i.e. the fields as part of each reference object contain new distances now. Note: Those distances will only be set if the object was affected by a kNN-classification. The new fields are overallCount, winningCount, losingCount, meanWinningDistance, meanLosingDistance, closestOverallDistance, closestWinningDistance and closestLosingDistance

• Standalone mode reaches feature parity with ES-based mode
  It is still possible to switch between modes. Standalone is not considered production ready yet, as some minor issues (see Milestone "Standalone") are not yet complete. ETA for a production-ready release - which removes all ES-features entirely - is v0.23.0 with ETA late December 2020.

  For details see #1265, #1249, #1271, #1272, #1281, #1250, #1291, #1278, #1286, #1308

New Deprecations

• winningDistance and losingDistance in _classification ref meta deprecated
  They have been replaced with meanLosingDistance and meanWinningDistance, see this deprecation notice for details.
