Highlights

• The Record interface type has been renamed to RecordBatch to align with other Arrow implementations and to avoid confusion. The old Record type is aliased to the new RecordBatch type so existing code works but users may wish to update references now. This work was contributed by a first-time contributor, @Mandukhai-Alimaa. See #466, #473, #478, and #486.

Important Note

• A side effect of the above was an unintentional breaking change by introducing a new method to the RecordReader interface. This shouldn't affect the majority of consumers, but is a breaking change for any who implemented their own concrete RecordReader type. The solution is simply to add a RecordBatch() method to the type when upgrading to v18.4.1
