Alpine Linux 3.0.0 is a security-oriented distribution designed primarily for servers. This is the first release in the 3.0 stable series. This is the first release with musl libc instead of uClibc and is not ABI compatible with earlier versions, so special care needs to be taken when upgrading. Since v2.7, among the various bug fixes, several packages have been upgraded: Linux kernel based on 3.14.5, LXC 1.0.3, QEMU 2.0.0, Asterisk 12.3.0, OpenSSH 6.6p1, OpenJDK 7, Varnish 4.0.0. Some of the desktop applications that got upgraded and are available for 3.0: X.Org Server 1.15.1, Firefox 29.0.1, Gnumeric 1.12.8, Evince 3.12, VLC 2.1.4, Inkscape 0.48.4, GIMP 2.8.10. A port for ARM has been created, but it is still experimental and not included in release builds.
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.
