Powered by the latest long-term supported (LTS) Linux 5.15 kernel series, Slackware 15.0 finally adopts the Pluggable Authentication Modules (PAM) for pure shadow passwords, switches to elogind as default user login and seat manager instead of ConsoleKit2, adopts the PipeWire low-level multimedia framework, and adds support for the Rust and Python 3 languages.
On the software front, Slackware 15.0 ships with the Xfce 4.16 and KDE Plasma 5.23 desktop environments, adds the Dovecot IMAP and POP3 server to replace the old imapd and ipop3d, drops support for Qt4 as Qt5 is now the norm, and introduces new scripts to help you easily rebuild the installer and to build kernel packages for your needs.
