╭───────────────────────────────────────────────────────────╮ VERSION 0.300 IS ALMOST OUT! ╰───────────────────────────────────────────────────────────╯ The long awaited feature to have stable ELPA packages is now available in the develop branch and we need to test it out before we release the 0.300 version. The stable ELPA repository is a Git repository, the official one is called Spacelpa and it is hosted on GitHub here: https://github.com/syl20bnr/spacelpa In the end only the master branch will use the stable ELPA repository and the develop branch will continue to use bleeding edge packages from MELPA essentially. Unfortunately this new feature requires at least Emacs 25.1 to work correctly as we need the archive priority feature of package.el that shipped with this version of Emacs. The ELPA repository configuration is set in a new immutable file called .lock that sits at the root of the Spacemacs git repository. Spacemacs downloads the whole ELPA stable repository locally so it means that once it is installed you don't need an Internet connection anymore to install any packages covered by Spacemacs layers! Default installation location of the ELPA stable repository is in: ~/.emacs.d/.cache/stable-elpa If you want to disable the ELPA stable repository put this in your dotfile in the user-init function: (setq configuration-layer-elpa-archives '(("melpa" . "melpa.org/packages/") ("gnu" . "elpa.gnu.org/packages/")))
