Changelog

v9.2 26 August 2024

It's huge release with many interesting updates:

And many smaller fixes and features

Breaking Changes

lvgl_private.h was introduced to better separate internal and public APIs and data. Your application might rely on APIs or data that are now available via lvgl_private.h.

Resolve it by either

  • include lvgl_private.h where needed

  • enable LV_USE_PRIVATE_API to internally include lvgl_private.h in lvgl.h
