The offical changelog of the latest release of Apple's upcoming iOS doesn't say much about what has changed under the hood.
Visually, we didn't spot anything different but performance-wise iOS 7 definitely feels snappier now. Still, we noticed the occasional persisitent bugs here and there.
Feature-wise, the new release brings along the redesigned Voice Memos app and the two new, more human-like voice for Siri in English - a male and a female one.
Perhaps the biggest change though is that the iPad (and iPad mini) developers and beta users will be able to join in on the iOS 7 fun now starting with this release.
Unfortunately, we don't have it installed on an iPad (yet), but we managed to snap a few screenshots off an iPhone 5. You can see how the Voice Memos app looks now.
If you find any other changes, please mention them in the comments below.
