In a surprising move, Apple has pushed up the release date of iOS 13.1 and iPadOS to September 24th. Both updates were initially scheduled for release on September 30th.
iOS 13.1 will be a pretty major update as apart from a host of bug fixes, it will also include a number of features like Shortcut Automations, Share ETA in Apple Maps, and more. These features were initially supposed to be a part of the iOS 13 release but Apple had to delay their release.
The company has already delayed a number of other iOS 13 features for later this fall including HomeKit Secure Video, Deep Fusion, iCloud Folder Sharing, Screen Time limits for individual contacts, and more.
iOS 13 contains a number of bugs so it makes sense for Apple to release the iOS 13.1 update earlier than planned and squash these bugs.
Alongside iOS 13.1, Apple will also release iPadOS to the public on September 24th. The update was supposed to go out on September 30 initially. iPadOS will bring major multitasking improvements to the iPad apart from an improved Safari with Download manager, Dark mode, and a new Reminders app. It will also pack almost all the features that are a part of iOS 13. The company does not mention the release build, but it is possible that the first public release of iPadOS will be iPadOS 13.1 instead of iPadOS 13.
As for tvOS 13, Apple will release it at the end of the month on September 30th.
