Alpine Linux is a unique distribution focused on lightweight and security. It uses musl instead of glibc and busybox instead of coreutils and a number of other packages. Programs in Alpine are built using Stack Smashing Protection.
Changes:
- initial integration of KDE and Gnome desktop environments;
- support for Raspberry Pi 4 (aarch64 and armv7);
- switching to linux-lts (version 5.4) instead of linux-vanilla (when upgrading, you will need to replace the package);
- support for Vulkan, MinGW-w64 and DXVK;
- Rust is available on all architectures except s390x,
- Python 2 has been deprecated and all packages will be removed in the next release.
- packages now use the path /var/mail instead of /var/spool/mail;
- package clamav-libunrar moved out of clamav hard dependencies;
- package versions updated.
