This is a minor (point) release in the 4MLinux STABLE channel, which comes with the Linux kernel 4.9.75 (*). The 4MLinux Server now includes Apache 2.4.29, MariaDB 10.2.11, and PHP 7.0.26 (see this post for more details). Additionally, some popular programs (Audacity, Chromium, VLC) have been updated, too. 4MLinux 23.2 includes bugfixes for VLC (which now plays the "https" network streams correctly) and Chromium (restored good sound quality).
You can update your 4MLinux by executing the "zk update" command in your terminal (fully automatic process).
The Linux kernel 4.9.75 is available for all supported 4MLinux and TheSSS versions to fix the Meltdown and Spectre vulnerabilities. Follow this link for details.
