[Trisquel-users] Kernel 4.4.0-143 in 2019?

[danielrobidoux49]

Hi
I just tried Trisquel-mini In virtualbox to test it
First of, im not a PC engineer, im actually very noob im PC's. However, im  
just trying to find a private and secure distro
So, i saw the kernel version was at 4.4.0-143
 I see other distro's with Kernel at 4.18 and above.
So, is anybody would like to explain to me how the 4.4.0-143 can be secure?
I see some activities in the forum, thats good. And, how's the  
developement/maintenance for Triquel in 2019?
Thank you
