Highlights

• [#7658]: Feature: Added EventManagerBase. We can now register managers that selectively process inputs e.g. touch and decide how to dispatch it to the widget tree. on_motion and motion_filter was added to Widget to handle generic motion inputs from the managers.
• [#7270]: Graphics: We now check whether the user called GL instructions from an external thread and raise an error.
• [#7293]: Properties: Added dynamic screen density/dpi support. KV code referencing density e.g. width: "5dp" will now update if the window dpi changes.
• [#7371]: KV: Allow using f-strings in KV-lang.
• [#7424]: Properties: Speed up bare widget creation (3X) and property dispatching/setting.
• [#7587]: Fix PermissionError when reconnecting mtdev input devices.
• [#7637]: Added Custom titlebar support.
• [#7642]: TextInput loading time optimization for large texts.
• [#7663]: Add python3.10 support.
• [#7678]: Add support for Apple Silicon.
