In programming, deprecated means something that is still supported now, but may not be supported in a future release. It usually refers to the C or C++ standard. However, compilers and/or libraries often deprecate things as well. (For example, VC++ caused a big stink by marking many standard library functions as deprecated without making it clear that they were only being deprecated by VC++ and not by the actual standard.)

It does (see Sang-drax's post).
