So, what's new with this upgrade? I'm glad you asked! (If you've been following the beta development, there might not be any surprises here)
First and foremost, the biggest upgrade comes in the base system. Newt OS LXDE 16.1.0 features Linux kernel 4.1, upgraded from 3.16. LXDE is still at version 0.8.1, but almost every other software package has been updated, including Firefox, Libreoffice, Shotwell, etc.
LightDM has replaced LXDM as the display manager (Login Screen software) to provide a more flexible setup to be used across all Newt OS flavors.
As far as system artwork is concerned, the default theme has been tweaked slightly. Also, the panel features improved "show-desktop" and menu icons. Newt OS still uses the Moka icon set by default. Also included is a new set of wallpapers (see post from a couple weeks ago for details).
For those using Newt OS LXDE 2.X.X, I apologize, but there is no upgrade path at this time. If you want the new artwork, software, and features, you will have to do a clean install. Make sure to back up any data you don't want to lose, as a reinstall will wipe your disk.
This is not the end of development for Newt OS until next year. It is merely a point at which anyone can use it without fear of finding bug infestations. There will be more fun developments to come!
