@since

(phpDocumentor 0.1+ )

@since --  Document when (at which version) an element was first added to a package

Description

@since version/info string

You may use the @since tag to document the release version of any element that can be documented (global variable, include, constant, function, define, class, variable, method, page). phpDocumentor will display the version/info string unaltered.

Use @since to document revisions, as in "This function has been a part of this package since version 2.0"

Here's an example:

/**
* Page-level DocBlock
* @package BigImportantProjectWithLotsofVersions
* @version 72.5
*/
/**
* function datafunction
* @since Version 21.1
*/
function datafunction()
{
...
}
