Changelog: Update to 2.12.1: * Add missing typing_extensions dependency for Python < 3.11 in #1150 Update to 2.12.0: * Annotate PyJWKSet.keys for pyright by @tamird in #1134 * Close HTTPError response to prevent ResourceWarning on Python 3.14 by @veeceey in #1133 * Do not keep algorithms dict in PyJWK instances by @akx in #1143 * Use PyJWK algorithm when encoding without explicit algorithm in #1148 * Docs: Add PyJWKClient API reference and document the two-tier caching system (JWK Set cache and signing key LRU cache). Update to 2.11.0: * Enforce ECDSA curve validation per RFC 7518 Section 3.4. * Fix build system warnings by @kurtmckee in #1105 * Validate key against allowed types for Algorithm family in #964 * Add iterator for JWKSet in #1041 * Validate iss claim is a string during encoding and decoding by @pachewise in #1040 * Improve typing/logic for options in decode, decode_complete by @pachewise in #1045 * Declare float supported type for lifespan and timeout by @nikitagashkov in #1068 * Fix SyntaxWarnings/DeprecationWarnings caused by invalid escape sequences by @kurtmckee in #1103 * Development: Build a sharedwheel once to speed up test suite setup times by @kurtmckee in #1114 * Development: Test type annotations across all supported Python versions, increase the strictness of the type checking, and remove the mypy pre-commit hook by @kurtmckee in #1112 * Support Python 3.14, and test against PyPy 3.10 and 3.11 by @kurtmckee in #1104 * Development: Migrate to build to test package building in CI by @kurtmckee in #1108 * Development: Improve coverage config and eliminate unused test suite code by @kurtmckee in #1115 * Docs: Standardize CHANGELOG links to PRs by @kurtmckee in #1110 * Docs: Fix Read the Docs builds by @kurtmckee in #1111 * Docs: Add example of using leeway with nbf by @djw8605 in #1034 * Docs: Refactored docs with autodoc; added PyJWS and jwt.algorithms docs by @pachewise in #1045 * Docs: Documentation improvements for "sub" and "jti" claims by @cleder in #1088 * Development: Add pyupgrade as a pre-commit hook by @kurtmckee in #1109 * Add minimum key length validation for HMAC and RSA keys (CWE-326). Warns by default via InsecureKeyLengthWarning when keys are below minimum recommended lengths per RFC 7518 Section 3.2 (HMAC) and NIST SP 800-131A (RSA). Pass enforce_minimum_key_length=True in options to PyJWT or PyJWS to raise InvalidKeyError instead. * Refactor PyJWT to own an internal PyJWS instance instead of calling global api_jws functions. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch". Alternatively you can run the command listed for your product: * SUSE Linux Micro 6.2 zypper in -t patch SUSE-SL-Micro-6.2-445=1 ## Package List: * SUSE Linux Micro 6.2 (noarch) * python313-PyJWT-2.12.1-160000.1.1 ## References: * https://www.suse.com/security/cve/CVE-2026-32597.html * https://bugzilla.suse.com/show_bug.cgi?id=1259616 .
