The fourth weekly test release of the Linux 3.15 kernel
is now available.
Linus Torvalds put out Linux 3.15-rc4 on Sunday as expected. He noted in the release announcement that nothing unusual went on in the past week and overall the activity is about normal for being about half-way through the RC releases.
There are some open issues still pending with the Linux 3.15 kernel, but Linus says, "on the whole things are fairly calm and nothing horribly scary. We're in the middle of the calming-down period, so that's just how I like it."
