3.0.0 - 2023-06-05

  • Add support for binary field length
  • Drop support for Python 3.6
  • Migration from 2.x.x:
    • 2.x.x used len_enc set to b and bcd to represent BCD length encoding.
    • 3.x.x changed that where len_enc set to b represents binary length encoding.
    • To migrate from 2.x.x update len_enc in all specificatations from b to bcd.

2.2.0 - 2022-01-30

  • Provide friendlier error messages when failing to encode/decode field, field length, and bitmap.
  • Clarify Binary-coded decimal field length configuration. Added bcd value to len_enc which is the same as the existing b value. Both mean that the length is to be encoded as BCD.

2.1.0 - 2020-12-24

  • Added support for fields measured in nibbles (half-bytes).

2.0.2 - 2020-11-20

  • Fixed issue #4. Encode secondary bitmap in upper case.

2.0.1 - 2020-08-22

  • Include inline type information into the distribution according to PEP 561.
  • Address remaining type hint issues.

2.0.0 - 2020-02-21

Backwards incompatible:
  • iso8583.decode is updated not to produce bitmap key 'bm'.
  • iso8583.encode is updated not to expect bitmap key 'bm' to define fields to encode. The decision on what fields to encode is based on numeric fields in the range of '1'-'128' present in the decoded dictionary.
  • iso8583.add_field and iso8583.del_field are removed. With the removal of bitmap set 'bm' default Python dictionary methods are enough.
  • iso8583.encode now removes secondary bitmap key '1' from the decoded dictionary if no '65'-'128' fields are present.
  • iso8583.pp function signature changed. The first parameter is renamed from doc_dec to doc.
Other changes:
  • iso8583.pp handles both encoded and decoded dictionary output.
  • iso8583.pp handles output folding. The defaul line width is set to 80. Line width can be configured using new line_width parameter.

1.0.2 - 2020-01-11

  • Optional proprietary header can now be parsed using standard field settings
  • Documentation improvements

1.0.1 - 2019-11-11

  • iso8583.decode and iso8583.decode now return a tuple
  • iso8583.decode returns a tuple of decoded dict instance and encoded dict instance
  • iso8583.encode returns a tuple of encoded bytes instance and encoded dict instance
  • Encoded and decoded dict instance keys are now all strings
  • Specification keys are now all strings

1.0.0 - 2019-11-04

Initial release.
