alt Hacker NewsBadly designed things get replaced. For example unique_ptr replaced auto_ptr. I'm not sure if the language standard actually supports the term "deprecation" though.
Edit: Also not sure what can possibly be downvoted here.

ISO/IEC 14882 contains many uses of the word "deprecation", including all the sections of Appendix D that explicitly lists all of the deprecated and removed features of the language and library.
auto_ptr is an exception. Not the rule.
Regular expressions in C++ are an example "everybody" advises against using, but it's still there. vector<bool> will stay forever and so on.
