The most annoying bug of iOS 7 was crashing of Safari. For iPad Air it happened for me all the time, every day 3-10 crashes during regular usage. Using other browser did not help - the problem was deeper, all browsers shared this issue. My biggest hope for 7.1 was this bug being fixed. But no, Safari still fails.
How to reproduce:
1. Go to someone's mobile.twitter.com account, like https://mobile.twitter.com/newsycombinator
2. Scroll down a few pages (for example, scroll down until 5 new pages load from infinite scrolling).
3. Scroll up very-very fast - Safari will fail.
This behavior did not change in 7.1, and this is not the only way to reprocude. Sometimes it just fails while opening a single page, without any other tabs opened.
I doubt it has anything todo with the number of tabs. I had hundreds of tabs open in Chrome. As Chrome keeps only the last few pages in memory, that's not an issue. But some very JavaScript heavy sites can be an issue, especially with devices that have only 512MB of memory.
