AIRR Standards v1.4.1

Version 1.4 of the AIRR Schema

Major Schema Changes:

• Updated quantification fields in the Rearrangement and Clone schemas for better
  compatibility with single-cell and emerging technologies. Changes include new
  optional fields and modifications to the semantics of existing *_count fields.
• Various new optional fields in the Study, Subject and Rearrangement schemas.
• Modified how time points and template concentrations are stored in Sample and
  NucleicAcidProcessing Schemas.

New Experimental Schema:

• Experimental releases of new single-cell associated schemas.
• Experimental releases of germline reference and genotype schemas.
• Experimental release of data aggregation schemas, including collections of repertoires
  and JSON/YAML files bundling multiple AIRR Data Model objects.

Major R and Python Library Changes:

• Added support for generalized AIRR Data Model files and objects that bundle
  multiple data classes.
• Deprecated support for files storing only Repertoire objects in favor of a general
  AIRR Data Model, which is backwards compatible with Repertoire metadata files.
