Apple has pushed first developer betas of iOS 13.4.5, iPadOS 13.4.5, tvOS 13.4.5, and macOS 10.15.5. The newest beta builds have been released just a week after we saw iOS 13.4, iPadOS 13.4, tvOS 13.4, and macOS 10.15.4 release. It is meant only for developers which means one should have a valid Apple developer account to get access.

As you might have guessed from the version numbers, it is not a major upgrade. These are minor updates with a focus on bug fixes and performance improvements. This is what is also mentioned in the official changelog which is a generic one. Abyssal zone classic mac os. It means Apple has not gone deep and offers specific details about bugs that have been fixed or what kind of improvements should be expected.
The only noteworthy thing here is that Apple has decided to jump directly to 13.4.5 and skipped all versions from 13.4.1 to 13.4.4. It seems like whenever the stable build will be released, it will also follow the same path. It seems like Apple did not have any major changes or fixes for beta testing and it simply took a leap.
If you are not a developer or someone who does not have a developer account, you will have to wait until the release of public betas. For developers, they can install the latest beta builds by visiting Apple's developer console. If you are already on the beta channel, the update will become available over the air.
