Apple released the second beta of iOS 13.3 and iPadOS 13.3, currently available only for registered developers. WatchOS 6.1.1 and tvOS 13.3 beta 3 released as well.
iOS 13.3 / iPadOS 13.3 beta 1 introduced several new features such as the option to disable the Memoji stickers from the keyboard and new options in Screen Time. The beta 3 should not bring any particular news, limiting itself to correct some bugs and to improve the general performances.
The same also applies to the beta 3 of tvOS 13.3 and watchOS 6.1.1.
