The Fedora Project, a Red Hat-sponsored and community-supported open source collaboration, has announced the release of Fedora 19 (code-named "Schrödinger's Cat"), the latest version of its free open source operating system distribution. The new release enables users of 3D printers, such as RepRap, to be fully satisfied with software in the repositories, without having to download binary blobs or run Python code from git; provides Kerberos enabled, LDAP replicated, two-factor authentication for FreeIPA; and updates GNOME to the latest upstream release. Detailed information about all the new features in the new release can be found here.
