+	Корректированы файлы "Makefile" для "FreePascal", добавлена возможность компиляции под Linux64.
+
+28.09.2023
+	Добавлена демка 20 "OpenGL33_2", показывающая работу с матрицами. В демо происходит вращение куба.
+
 18.09.2023
 	Добавлено определение "CLEAR_STATE". Теперь если его отключить, то не будут очищаться события клавиатуры, мыши, джойстика и тачпада. Пользователю надо будет самому определить где он будет очищать данные события.
