v5.11.0

KemonoDownloader 5.11.0 Release

Feature Update
Welcome to the KemonoDownloader 5.11.0 release!

This version introduces dynamic domain configuration with full support for pawchive.st, centralizes domain handling for easier maintenance, updates license metadata to modern PEP 639 standards, significantly improves download reliability and system compatibility (especially on Linux), and delivers a major expansion of the test suite along with CI stability fixes.

The biggest highlights are:

• Dynamic domain configuration — centralized assets/config/domain file supporting kemono.cr, coomer.st, and the new pawchive.st
• PEP 639 compliant license definitions in pyproject.toml
• Better Linux compatibility via XDG_DATA_HOME fallback and robust interruption handling
• Massive test suite growth (100+ new tests) + headless CI stability improvements

As always, KemonoDownloader remains fully open-source and free to use, modify, and build.

Site Availability Status

As of June 17, 2026, the media download servers for Kemono.cr and Coomer.st are currently unavailable or not being updated. To ensure continued functionality, Pawchive.st has been added as an alternative source for content.
