Alpine Linux 3.6.0 has been released

Alpine Linux 3.6.0 has been released
Alpine Linux 3.6.0 released
Alpine Linux version 3.6 has been released. Alpine Linux is built around musl libc and busybox. This makes it smaller and more resource efficient than traditional GNU/Linux distributions. A container requires no more than 8 MB, and a minimal installation to disk requires around 130 MB of storage. Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository. Alpine Linux was designed with security in mind. The kernel is patched with an unofficial port of grsecurity/PaX, and all userland binaries are compiled as Position Independent Executables (PIE) with stack smashing protection. These proactive security features prevent exploitation of entire classes of zero-day and other vulnerabilities.
