Kernel 4.10.2-x86_64-exton is my newest Slackware kernel. The stable kernel 4.10.2 was released by Kernel.org on March 12, 2017.
I have compiled a very useful (as I think) 64 bit kernel for Slackware Current (14.2) and/or all Slackware derivatives. For example Slax, Zenwalk and SlackEX. The kernel is compiled exactly in the same way as Slackware’s latest kernel huge. “My” kernel 4.10.2-x86_64-exton has even more support for new hardware, etc. Kernel 4.10.2 is the latest kernel available from Kernel.org. Released 20170312.
