I have Emacs 24.3.1 and I'd like to upgrade to the latest Emacs 24.4.x. All documentation that I have visited suggests building from a tarball or source. Is there a reason why there are no package manager options to upgrade my Emacs? If not, how do I upgrade my Emacs using the package manager?
Here is some info about my Emacs, which I believe comes default on Ubuntu 14.04:
emacs:
Installed: 45.0ubuntu1
Candidate: 45.0ubuntu1
