Version 1.5.0:  August 29, 2023
-------------------------------------------------------------------------------
 
+ Updated schema set and examples to v1.5.


Version 1.4.1:  August 27, 2022
-------------------------------------------------------------------------------

Significant internal refactoring to improve schema generalizability,
harmonize behavior between the python and R libraries, and prepare for
AIRR Standards v2.0.
   
Rearrangement:

+ Added the `aux_types` argument to `read_tabular`, `read_rearrangement`, and 
  `read_alignment` to allow explicit declaration of the type for fields that 
  are not defined in the schema.
+ Renamed `read_airr`, `write_airr`, and `validate_airr` to `read_tabular`,
  `validate_tabular`, and `validate_tabular`, respectively.

Data Model and Schema:

+ Defined new `read_airr`, `write_airr`, and `validate_airr` functions that
  support AIRR Data Model files that store arrays of objects in JSON or YAML.
+ Added support for the AIRR Model Data File and associated schema
  (DataFile, Info). The Data File data format holds AIRR object of
  multiple types and is backwards compatible with Repertoire metadata.
+ Added support for the new germline and genotyping schema
  (GermlineSet, GenotypeSet) and associated schema.

  `germline_alignment` data and simplification of `sequence_id` values.
