The new beta builds can be picked up by developers taking part in the test program as an over-the-air update on devices that have been used for previous betas, or via the Apple Developer Center. Public beta versions of each beta operating system release typically arrive shortly after the developer betas, via the Apple Beta Software Program website.
The first generation of betas for the current cycle were issued on February 5.
The first iOS and iPadOS 13.4 betas include quite a few changes, including the return of iCloud folder sharing, which was originally promised for iOS 13 but was removed before its release.
