[meta-freescale] latest stable kernel version for i.MX6

[Marco]

Hello,
I am using Yocto dora with an imx6dlsabre and I see that it uses the 
3.0.35 (4.1.0) kernel version.
I wonder if there is any other more recent kernel version provided by 
Freescale.
In meta-freescale ML I have found a thead about 3.10.9-1.0.0-alpha kernel.
Is it safe to use it, or when it will be?
Do you have a link to the Freescale kernel repo?

Thank you
