I'm announcing the release of the 4.4.142 kernel.
It's not an "essencial" upgrade, but a number of build problems with perf are now resolved, and an x86 issue that some people might have hit is now handled properly. If those were problems for you, please upgrade.
The updated 4.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git%3Ba=summar...
thanks,
greg k-h
