Kernel 4.4.3 has been released, bringing updated drivers and filesystem enhancements.

Also worth mentioning: Starting with Kernel 4.0 the long awaited Life Patching feature has been implemented, permitting the users to update the kernel without having to reboot the system. While this is not important for regular users, this feature is very good for Linux servers.
Installation instructions:
The ElRepo repository provides the latest stable version of the kernel for CentOS 7, Enterprise Linux 7 and RHEL 7.
In order to install the kernel patch, you need to add the repository’s key to your system, install the repository and enable the repo and install the kernel-ml package:
$ su root
# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
# yum install http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
# yum --enablerepo=elrepo-kernel install kernel-ml
Reboot and choose Kernel 4.4.4 at startup:
# reboot
Optional, to remove kernel 4.4.4 do:
# yum remove kernel-ml
