⚠️ API changes

For Library.get_description_batch, Library.read_metadata_batch and Library.write_batch, a DataError object will now be returned in the position in the list returned corresponding to the symbol/version pair there was an issue reading/writing. Note this may require code changes to support the new error handling behaviour - as a result it is being considered a breaking change as described above.

  • get description batch method: method rationalisation (#814)
  • read metadata batch method: method rationalisation (#814)
  • Write batch method: method rationalisation (#814)
