Your catch-all General settings have largely gone unchanged, save for a few rearrangements and one new addition.
ABOUT The only change in the About section is the removal of the Diagnostics & Usage item.
SIRI Siri can now respond to your cry of "Hey Siri" when your iPhone is connected to a power source — just toggle on Allow "Hey Siri" to try this out. This has replaced the Raise to Speak option from iOS 7.
SPOTLIGHT SEARCH iOS 8 introduces two additional categories that can be included in Spotlight Search, which you access by swiping down on the screen. Spotlight Search now digs up Spotlight Suggestions and Bing Web Results. Warning: You might want to check out the Spotlight Suggestions & Privacy disclaimer at the bottom.
HANDOFF & SUGGESTED APPS This is a new section for two new features. Handoff lets you start something on one device and pick it up on another device, linked together by iCloud. Of course, there are some caveats: Mobile devices must be running iOS 8, and your Mac or MacBook must be running OS X Yosemite — which hasn't shipped yet. This is part of Apple's Continuity plan, and we can't wait to put it to the test.
As for Suggested Apps, this feature will recommend apps for you to use depending on your current location and display them on your lock screen. Toggle on My Apps to get suggestions on apps you already have installed; Toggle on App Store for recommendations for apps you don't own, but that your iPhone thinks will be useful.
ACCESSIBILITY This section has actually changed quite a bit, offering a wider range of options for those who need assistance. Options are broken down into different categories, starting with Vision. To start, the Text Size controls have been folded into Accessibility; you'll find them by tapping Larger Text, and then use the scroll panel to set the size. You'll also notice a new toggle for Grayscale, and a new category for Speech controls, with toggles for Speak Selection, Speak Screen, and Speak Auto-text (which used to be found on the main Accessibility screen, but have now been condensed).
VoiceOver has a few tweaks, including updates to the adorable tortoise and hare icons on the Speaking Rate control slider. Where the Use Compact Voice toggle once was, you'll find an option for Speech, where you can select your dialect based on your language (which used to be a standalone Accessibility control) and add a rotor language. Braille has a couple of more in-depth options, including the braille display's output and input types (six-dot, eight-dot, or contracted), and a toggle to turn pages when panning. Rotor has two new additions: Audio Ducking and Braille Screen Input. Another new control is Typing Style; iOS 8 supports Standard Typing, Touch Typing, or Direct Touch Typing.
