March 2021 (version 1.46.0)

Welcome to the new DeepScan updates. We skipped February release due to the long Lunar New Year Holidays. 2021 is the year of ox. The world is growing and recovering slowly. Let's work hard and stay strong like an ox then we will succeed eventually as oxen do.

Thank you for your continual love and support!
