Dear Valued Customer,

We are contacting you today to announce that Linux 4.9 is now available for TS-7680, TS-7400-V2 & TS-7670, extending security support to 2022.  Technologic Systems strives to support our customers with security needs while also maintaining long product availability without significant changes.  To do this for these products, we've made available a supplemental image with long term support from the Linux community. The stock shipping image will remain unchanged but we now offer an after-market image with an updated Linux 4.9 kernel and Debian Stretch available from and supported by us directly.

The affected products are: TS-7400-V2, TS-7670, TS-7680 (and any custom variants)

Linux 4.9 is an LTS kernel release that will be maintained by the Linux community until 2023, including back-porting of security patches. Debian Stretch is the current stable Debian release with long term support until 2022. These make the above products an ideal candidate for current applications that need the latest security patches.  Most often, it will be possible to directly merge in future upstream changes into this new kernel with no conflicts.
