Change Log

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.
