Badly 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.

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.
