Emacs 24.3 Common Lisp Package Name Change

By Xah Lee. Date: . Last updated: .

if you get warning messages like these:

don't worry about it. Those functions are from Common Lisp library. In emacs 24.3, they made changes to the naming so most of them now starts with “cl-”.

most packages are still using the old name, and may not switch over for a while. Because, if one simply switch, then it won't work with older emacs. They have to check version first, or set up alias, but that gets a bit involved.
