Apple has just released iOS 13.3.1, iPadOS 13.3.1, macOS 10.15.3, watchOS 6.1.2, tvOS 13.1.1, and Software 13.3.1 for HomePod to all eligible users. iOS 13.3.1 and iPadOS 13.3.1 is now available for download via Settings -> General -> Software Update, whilst the macOS 10.15.3 can be downloaded from the Mac App Store using the Update feature in the System Preferences app.

iOS 13.3.1 introduced a new toggle that allow users to disable Ultra Wideband chip on the iPhone 11 and iPhone 11 Pro models, this can be done with a new switch "Location for Networking & Wireless" that Apple added in beta 2. However, if it is switched off, it will not only affect UWB but also impact the use of Bluetooth and Wi-Fi. In addition, the update include bug fixes for Mail and Screen Time:

- Fixes an issue in Communication Limits that could allow a contact to be added without entering the Screen Time passcode
- Adds a setting to control the use of location services by the U1 Ultra Wideband chip
- Addresses an issue that could cause a momentary delay before editing a Deep Fusion photo taken on ‌iPhone 11‌ or iPhone 11 Pro
- Resolves an issue with Mail that could cause remote images to load even when the “Load Remote Images” setting is disabled
- Fixes an issue that could cause multiple undo dialogs to appear in Mail
- Addresses an issue where FaceTime could use the rear facing ultra-wide camera instead of the wide camera
- Resolves an issue where push notifications could fail to be delivered over Wi-Fi
- Addresses a CarPlay issue that could cause distorted sound when making phone calls in certain vehicles
- Introduces support for Indian English Siri voices for HomePod

macOS 10.15.3, on the other hand, contains Pro Display XDR optimizations and multi-stream video editing improvements. Though it's not clear if the so-called "Pro Mode" is coming to Mac with this release:

- Optimizes gamma handling of low gray levels on Pro Display XDR for SDR workflows when using macOS
- Improves multi-stream video editing performance for HEVC and H.264 encoded 4K video on the 16-inch MacBook Pro (2019)

Unceasingly, both tvOS 13.1.1 and watchOS 6.1.2 brings any new features and changes, as Apple just provides little to no information on them, so it's possible that they include performance improvements and bug fixes.
