I follow the Planet Emacsen blog to keep updated on everything Emacs and this is where I found out about this notable change. I thought it would be useful here to also to highlight the fact that the melpa.milkbox.net packages url has changed to melpa.org.
If you are already using the melpa package repository you have to change your .emacs file from (“melpa” . “http://melpa.milkbox.net/packages/”) to (“melpa” . “http://melpa.org/packages/”)
It’s a simple change but it might catch some folks who haven’t been paying attention off guard.
