List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:219669 Archived-At: I maintain some Emacs packages that work on Emacs 25. It's been requested that I adjust them so that they will also work on Emacs 24. One way to do this is to install Emacs 24, try to use the packages, and see what errors I get. Is there a better way than this? For example, some package that scans my code and checks if I use any variables or functions that were only added in recent versions of Emacs. Thanks, Radon Rosborough
