v3.5.0

Breaking changes

• Drop support for Python 3.8 (PR: #326)

Changes

• Use importlib.resources to load bundled data files so that Biip can be installed as a zip file. (PR: #324, #327)
• Update all bundled GS1 datasets. The GS1 Company prefixes is the only dataset with any changes.
• Test on Python 3.13

v3.4.0

Changes

• Accept redundant GS1 Message separator chars, both after fixed-length fields and at the end of the GS1 Message. The specification says that the separator characters "should not" be present in these locations, but doesn't forbid it. Multiple separator characters are also ignored. (Fixes: #176, PR: #304)

v3.3.0

Changes

• Add support for extracting dates and potentially datetimes from GS1 messages with AI 4324/4325/4326/7003/7006/7007/7011/8008. (PR: #301)

Fixes

• In the new GS1 AI dataset introduced in Biip 3.2.0, there are four AIs with optional pattern groups. When the value matches everything but the optional pattern group, the group's value becomes None. This caused Biip to crash when we tried building a string of the characters matching the pattern. (Fixes: #295, PR: #300)

v3.0.0

This release contains a couple of breaking changes, thus the version bump to 3.0.

Breaking changes

• Parsing and validation errors of GLNs, GTINs, and SSCCs nested inside GS1 Element Strings no longer raises ParseError. Instead, the exception message is exposed on the GS1ElementString class as the new fields gln_error, gtin_error, and sscc_error. This is a breaking change, but makes it possible to extract some information from GS1 Element Strings that are not entirely valid. (Fixes: #157, PR: #169)
• Remove RcnRegion.from_iso_3166_1_numeric_code() class method which as been deprecated since Biip 2.2. (Fixes: #161, PR: #166)

GS1 Company Prefix support

• Add GS1CompanyPrefix class that can extract the company prefix from any GLN, GTIN, or SSCC. This is based on a data set from GS1 that is bundled with Biip, just like the GS1 Prefixes and GS1 Application Identifiers. The data set is preprocessed into a trie data structure, making company prefix length lookups fast. (Fixes: #160, PR: #172)
• Add and set company_prefix fields on the Gln, Gtin, and Sssc classes, based on the new GS1CompanyPrefix class. (Fixes: #160, PR: #174)
• Change Sscc.as_hri() to use GS1CompanyPrefix to automatically group the company prefix and the serial when rendering SSCC's for human consumption. The existing company_prefix_length parameter is now only used as an override in case you're rendering an SSCC whose company prefix is not included in the data set yet, or where you disagree with the data set. (Fixes: #160, PR: #173)

Other changes

• Add rcn_verify_variable_measure parameter to all functions and methods taking rcn_region as a parameter. The parameter defaults to True and the old behavior. By setting this parameter to False, it is possible to parse and extract variable measure from RCNs that have separate check digit for the variable measure, but where the check digit is either incorrect or simply not in use as a check digit. This parameter only has any effect on RCN regions with formats including check digits, e.g. Great Britain and Germany. (PR: #171)
• Update the bundled GS1 Application Identifier definitions. (PR: #164)
• Update the bundled GS1 Prefix definitions, and add script to automate future updates. (PR: #165)
• Add Python 3.11 to the test matrix, and updated development tooling. (PR: #163)

v2.3.0

Changes

• Add support for parsing GS1 Human Readable Interpretation (HRI) strings. HRI strings is the text typically printed below or next to GS1 element string barcodes. (PR: #155 and #156)
• Update the bundled GS1 Application Identifier definitions.

v2.2.4

Bug fixes

• Fix crash on parsing of zero-prefixed RCNs. (PR: #150)

If you're using Biip, please add yourself to the list of users!

v2.2.3

Bug fixes

• Fix crash in decimal parsing of GS1 Message. Some GS1 AI patterns allow a group to be empty. Biip tried to parse these as decimal numbers without checking if it had anything to parse first, causing a crash. (PR: #149)
