  • Use --regex-variant nonunicode to get non-unicode JS regular expressions, the default behavior from previous versions.
  • Custom validators may be impacted by the new regular expression features. Validators are now always modified with the jsonschema library's extend() API to control the pattern and patternProperties keywords.

• Update vendored schemas: github-workflows, renovate, woodpecker-ci (2024-07-07)
• Improve caching to include caching of remote $ref downloads. This should improve performance in cases where a schema has many remote refs and is used in repeat invocations. The $ref cache can be disabled via the same --no-cache flag which disables use of the pre-existing cache. Thanks @alex1701c! (#452, #454)

• Include built-in, efficient implementations of date-time format validation (RFC 3339) and time format validation (ISO 8601). This makes the date-time and time formats always available for validation. (#378)
• Support the use of orjson for faster JSON parsing when it is installed. This makes it an optional parser which is preferred over the default json module when it is available.
• TOML parsing is now always available (rather than an optional parser). This change adds a dependency on tomli on older Python versions, ensuring that TOML formatted data is always supported. Users should no longer need to install tomli manually in order to use TOML files.

• Update vendored schemas: dependabot, github-workflows, renovate (2023-11-24)
• Add official support for Python 3.12

What's Changed

• Fix bugs related to the new $ref resolution behavior (https://github.com/python-jsonschema/check-jsonschema/pull/298)

Full Changelog: https://github.com/python-jsonschema/check-jsonschema/compare/0.24.0...0.24.1

<!-- Release notes generated using configuration in .github/release.yml at 0.24.0 -->

What's Changed

• Drop support for python3.7
• Update vendored schemas: github-actions, gitlab-ci, readthedocs, renovate, travis (2023-08-08)
• Use the new referencing implementation in jsonschema (https://github.com/python-jsonschema/check-jsonschema/pull/289)
  • The minimum supported version of the jsonschema library is now 4.18.0, which introduces new $ref resolution behavior and fixes. That behavior is used in all cases, which should result in faster evaluation especially on large schemas.
  • $ref usage may now refer to YAML, TOML, or JSON5 files, or any other non-JSON format supported by check-jsonschema. The file type is inferred only from the file extension in these cases and defaults to JSON if there is no recognizable extension.
• Remote schemafiles (http/s) now support YAML, TOML, and JSON5 formats, if the URL ends with the appropriate extension and the matching parser is available. Extensionless URLs are treated as JSON. (https://github.com/python-jsonschema/check-jsonschema/pull/295)

• Update vendored schemas: github-workflows, gitlab-ci, renovate (2023-01-24)

• Fix a bug in which --check-metaschema was not building validators correctly. The metaschema's schema dialect is chosen correctly now, and metaschema formats are now checked by default. This can be disabled with --disable-format.

• Fix the resolution of $schema dialect to format checker classes

• Fix package dependency lower bounds, including setting jsonschema>=4.5.1

• Output colorization can now be controlled with --color [never|always|auto]. Thanks WillDaSilva!

• Update vendored schemas: bamboo-spec, buildkite, dependabot, github-actions, github-workflows, gitlab-ci, readthedocs, renovate, travis (2023-01-03)

• Add Buildkite schema and pre-commit hook (198)

• Update vendored schemas: gitlab-ci, renovate (2022-11-14)

• Update vendored schemas: bamboo-spec, dependabot, github-workflows, gitlab-ci, renovate (2022-10-20)

• Tweak format checker usage to avoid deprecation warning from jsonschema

• The Azure Pipelines data transform is now more permissive, which should allow it to handle a wider variety of pipelines files (162)
