Linus Torvalds acknowledged in his 3.14-rc2 release announcement "it's been pretty quiet", but he's scared of large pull requests coming in next week or later on in this kernel development cycle. For the changes that were merged this week, it's been the usual fixes to drivers, architecture updates, etc. There really isn't anything too exciting this week.
If you're not yet running the Linux 3.14 kernel in its latest development form and unaware of the many new features, read our overview of the Linux 3.14 features. There's a lot of good stuff in this release! We'll have out more Linux 3.14 kernel benchmarks on Phoronix in the days ahead now that most of the initial fixes have landed. There's also daily Linux kernel benchmarks coming along with other high-profile projects.
