[dependabot]

Updates the requirements on python-keycloak to permit the latest version.

Changelog

Sourced from python-keycloak's changelog.

v7.1.1 (2026-02-15)

Fix

• uma: set requested resource ids correctly in permission ticket creation (#702)

v7.1.0 (2026-02-13)

Feat

• decode token with all keys, added get client certificate info method (#704)

v7.0.3 (2026-01-28)

Fix

• do not throw when processing signed userinfo response (#699)

v7.0.2 (2026-01-08)

Fix

• Fix/python version and ci (#691)

v7.0.1 (2026-01-05)

Fix

• python version

v7.0.0 (2026-01-04)

BREAKING CHANGE

• this change introduces a very strong typing across the library. From now on, we demand that each method returns a single type and converts the results into the specified return type, otherwise it raises a TypeError exception. This should resolve any type checking linter errors within the library as well.

Fix

• updated lockfile
• pass along the default connection manager configuration into uma
• dont override transport for httpx
• pass query params in get groups
• removed async property as a dependency
• strong and consistent typing across the library

v6.0.0 (2025-12-28)

BREAKING CHANGE

• changes the behavior of get_group_by_path to raise an exception in case the path is not found, which is now the definitive new behavior

Closing: major version bump (python-keycloak 5.5.1 → 7.1.1). This skips a major version (5→7) and likely has breaking API changes. Requires manual validation of the image_service Keycloak integration.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
