Python 3 library for providing a base clients for interacting with the Kognic platform

Changelog

All notable changes to this library will be documented in this file

[2.6.0] - 2026-09-25

• Failing API calls now carry the platform's own explanation of the failure.

[2.5.2] - 2026-09-18

• Dependency ceiling only: kognic-auth widened to >=3.0.0,<5. No functional changes.

[2.5.1] - 2026-08-18

[2.5.0] - 2026-05-04

• Drop support for Python 3.9. The minimum supported version is now Python 3.10.
• Fix file uploads silently uploading empty content after a transient failure. The upload handler now rewinds seekable streams and recreates file-backed streams between retry attempts, and disables retries for streams that cannot be re-read.
• File-like objects passed to the upload handler are now closed by the handler once the upload finishes. Callers that pass an already-open file should not close it themselves.
