+MindSpore's top priority plans in the year are displayed as follows. We will continuously adjust the priority based on user feedback.
+
 In general, we will make continuous improvements in the following aspects:
 1. Support more preset models.
 2. Continuously supplement APIs and operator libraries to improve usability and programming experience.
