  • Improvement: Better startup performance for databases using fulltext.
  • Improvement: Enhanced the Getting Started examples to include the Pull API and find specifications.
  • Improvement: Better scheduling of indexing jobs during bursty transaction volumes
  • Fixed bug where Pull API could incorrectly return renamed attributes.
  • Fixed bug that caused `db.fn/cas` to throw an exception when `false` was passed as the new value.
