Guix 1.3

We are pleased to announce the release of GNU Guix version 1.3.0! A distinguishing Guix feature is its support for declarative deployment: instead of running a bunch of guix install and guix remove commands, you run guix package -manifest=manifest. Building on the Guix System image API introduced in v1.2.0, the guix system vm-image and guix system disk-image are superseded by a unified guix system image command. Last but not least, the introduction of the GUIX EXTENSIONS PATH Guix search path should make it possible for Guix extensions, such as the Guix Workflow Language, to have their Guile modules automatically discovered, simplifying their deployments. Guix publish has a new -advertise option to advertise itself on the LAN. On Guix System, you can run herd discover guix-daemon on to turn discovery on temporarily, or you can enable it in your system configuration. In other news, guix system init has been optimized, which contributes to making Guix System installation faster. GNU Guix is a transactional package manager and an advanced distribution of the GNU system that respects user freedom.
