This package supersedes the subfigure package (which will continue to be supported, but no longer maintained). The name has changed because the subfig package is not completely backward compatible with the older subfigure package due to an extensive rewrite to use the new caption package to produce its subcaptions. The major advantage to the new package is that the user interface is keyword/value driven and easier to use. To ease the transition from the subfigure package it includes a configuration file (subfig.cfg) which nearly emulates the subfigure package. The author is Steven Douglas Cochran.
