Since July 2016 we haven't heard from Slackware. Distribution stopped at version Slackware Linux 14.2.
So today we are pleased to announce the upcoming version 15.0 of the oldest surviving Linux distribution in the world.
The new version has been declared in the "Current" development branch as "alpha 1":
"Here we go again gl the glibc 2.33 has been upgraded and comes with one latest mass rebuild in Slackware 15.0. The only packages upgraded to this batch are glibc and kernels - everything else is just a remake of the new glibc.
There's also a new Rust compiler, but the Firefox and Thunderbird apps will need to be patched to use it, so we'll leave them until we're ready with the new Rust for the updates code or the new upstream versions.
That's why I'm not ready to name the "beta" version yet, and we'll call it 15.0-alpha1. "
Read full changelog. Slackware does not have official ISOs for testing, but one of the distribution's developers, Eric Hameleers, regularly creates unofficial DVDs installations from the “Current” dev branch of Slackware.
