Apple's just rolled out iOS 8.1.1 for iPhone, iPad, and iPod touch. Aside from the usual promise of bug fixes and security updates, Apple says the latest release should speed things up on iPad 2 and iPhone 4S, two of the company's aging devices. We've seen it several times: installing major new versions of iOS on old hardware can often result in degraded performance, making the user experience slower and worse than it had been before. That was true with iOS 7 last year, and now again Apple is working to make things better for customers still holding onto old products.
There's also an update on the Mac side: Apple has released OS X 10.10.1, its first update to Yosemite. Apple says the release should result in better Wi-Fi reliability, improved Microsoft Exchange connections, and fixes for reliability in Mail when sending messages using "certain" email providers. And if you use Apple's Back to My Mac feature, OS X 10.10.1 should make that work better in Yosemite, as well. You can download the latest release from the updates tab at Apple's Mac App Store.
