Deprecated

In computer terminology, deprecated designates features or methods that are considered obsolete and are being "phased out".

For example, the markup language HTML, used for web pages, has been standardized by the World Wide Web Consortium. Whenever a newer version of HTML is published, W3C may decide that some old HTML style tags are not needed, since new methods exist to express the same thing. Such tags are said to be deprecated.

This means the members of W3C have decided not to guarantee their availability in future versions of HTML. Popular web browsers still understand most deprecated tags. However, a new browser may ignore them while being advertised as "HTML 4.0 compliant".
