The Kivy team is happy to announce the release of Kivy 2.3.0

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 3.7-3.12

This marks the final release of the 2.x.x series. Note that anything deprecated in 1.x.x and 2.x.x will be removed in the upcoming major version, 3.0.0. Scheduled removals and notable changes for Kivy 3.0.0 will be detailed in an upcoming statement over the next few weeks.

This release is the last to support Python 3.7 and Windows 32-bit. We strongly encourage users to migrate their environments accordingly.
