## Change History
* 2023/04/01 (v21.3.9)
- Update how setup is done on Windows by introducing a setup.bat script. This will make it easier to install/re-install on Windows if needed. Many thanks to @missionfloyd for his PR: https://github.com/bmaltais/kohya_ss/pull/496
* 2023/03/30 (v21.3.8)
- Fix issue with LyCORIS version not being found: https://github.com/bmaltais/kohya_ss/issues/481
* 2023/03/29 (v21.3.7)
