Based on Gentoo, Calculate Linux 20.6 is here to celebrate the 20th anniversary of the Calculate Linux project and introduces some major performance improvements through the use of Zram as a replacement for the traditional Swap partition and Zstd for the Linux kernel, modules and initramfs. In addition, kernel modules that are installed as packages come as Zstd archives too. Furthermore, this release switches to PulseAudio as default sound system for better audio, improved Wi-Fi support, improves the removal of orphan dependencies, implements suspend action for laptops when closing the lid, and adds pre-configured Passman and FreedomMarks web browser extensions for Nextcloud support. Also, Chromium comes with pre-configured uBlock Origin add-on for blocking ads.
