deprecated

The following are some examples of deprecation:

Computer programming

In computer programming, a deprecated language entity is one that is tolerated or supported but not recommended.

For example, a number of elements and attributes are deprecated in HTML 4.0, meaning that other means of accomplishing the task are preferred. Many deprecated features became obsolete in HTML5, although browsers that support the features may continue to support them.

In the Java programming language, a particular method may be deprecated for a given class of objects.

Security through obscurity

Even general approaches to something can be deprecated. Security through obscurity, for example, is an approach that relies on keeping coding and its potential vulnerabilities hidden so that flaws are less likely to be detected and exploited.

That model, and others such as security through minority and security through obsolescence, are deprecated in favor of security The concept of deprecated features also extends to software. In this case, it may refer to a program or application that is no longer supported or maintained At some point, all software becomes deprecated as new versions are released and older ones are no longer supported. But in some cases, particular software may become deprecated ahead of its time as a result of changes in technology or user preferences.

For example, the Mozilla Firefox web browser deprecated its built-in RSS and Atom feed reader in 2016. The move was made in part because of the declining popularity of RSS and Atom feeds, as well as changes in how people consume content online.

While deprecated software is no longer supported, it may continue to work. In some cases, however, deprecated software may stop working entirely if, for example, it is incompatible with an updated operating system.
