Alpine Linux 3.2.0 is a security-oriented distribution built from scratch and designed primarily for server deployments (and with some desktop packages available from the project's online repositories). This release is built with musl libc and is not compatible with 2.x and earlier, so special care needs to be taken when upgrading. Please refer to the documentation for information on how to perform the upgrade. Some of the new features are: Linux kernel 3.18; GCC 4.9.2 / musl 1.1.9 + fortify; MariaDB 5.5 replaces MySQL; Postfix 3.0; Lua 5.3 support; Ruby 2.2; Xen 4.5; Samba 4.2; MATE desktop 1.10; LibreOffice 4.4; Qt 5.4; Kodi (previously known as XBMC) 14.2. Some of the desktop applications that got upgraded and are available for 3.2: Xfce 4.12; X.Org Server 1.17; Firefox 38; Evince 3.16; virt-manager 1.2; VLC 2.2; Inkscape 0.91; Audacity 2.1.
About Alpine Linux
Alpine Linux is a community developed operating system designed for x86 routers, firewalls, VPNs, VoIP boxes and servers. It was designed with security in mind; it has proactive security features like PaX and SSP that prevent security holes in the software to be exploited. The C library used is musl and the base tools are all in BusyBox. Those are normally found in embedded systems and are smaller than the tools found in GNU/Linux systems.
