2.3.1

The Kivy team is happy to announce the release of Kivy 2.3.1

Kivy is an open-source Python framework for developing GUI apps that work cross-platform, including desktop, mobile and embedded platforms.

Kivy is MIT licensed, actively developed by a great community and is supported by many projects managed by the Kivy Organization.

Installation instructions and Kivy Docs are hosted on the Kivy Website

Currently supported Python versions are 3.8-3.13

This is a bugfix release of the 2.3.x series, which we decided to keep updated to offer a stable solution while we develop the next major version, 3.0.0.

As stated during 2.3.0 release, support for Windows 32 bit and Python 3.7 has been removed. Instead, support for Python 3.13 has been included in this release.
