Ubuntu – How to upgrade to the latest Emacs


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:

  Installed: 45.0ubuntu1
  Candidate: 45.0ubuntu1
  Version table:
 *** 45.0ubuntu1 0
        500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status

Emacs 24.4 is still relatively new. Ubuntu is considered a stable distro, and for that reason software sometimes lags behind. If Emacs 24.4 isn't packaged, you'll need to build it yourself.
