There is nothing as exciting in the beta testing world as a new update. Fight with overloaded servers to download the latest update as quickly as possible, just to scour through the new operating system and look for the biggest features for the smallest changes. It wasn't until Thursday that Apple saw iOS 13.2 developer beta 2, so count on us being surprised to see today's release of developer beta 3 as soon as possible.
We don't know what the new update has stored for iOS 13.2 as a whole until we spend some time with it. Dev beta 2 introduced a handful of changes to dev beta 1, including a series of new emojis, camera settings in the 2019 iPhone app, new Siri & Dictation security options, and options to remove home screen apps through a quick fix.  Unfortunately, this update is for registered developers only. The public beta may arrive until 4 pm. EDT (1 p.m. PDT), but if not, we expect to see it at 1 p.m. EDT (10am PDT) tomorrow, Thursday 17 October.
Apple's release notes usually provide context for all new changes found in beta, especially those related to bugs and developer features. However, this beta does not include any information in the release notes, confirmed by Apple itself. What this means for dev beta 3 as a whole is anyone's guess:

To update your iPhone to iOS 13.2 dev beta 3, you must be a registered developer. You can use the recovery image for your iPhone located in the Developer Portal (install with iTunes or Finder) or install the configuration profile and then refresh over the air. If you have already installed the profile on your iPhone, go to Settings -> General -> Software Update to start installing the latest beta, or wait until it installs automatically if "Automatic Updates" is enabled.
