Technical Notes: Legacy Technologies
As Mac OS X and Apple hardware devices evolve, the APIs and technologies they encompass change to meet the needs of developers and users. As part of this evolution, less efficient features, interfaces, and programming techniques are deprecated or retired in favor of newer ones. Apple makes these changes only when deemed absolutely necessary. A technology identified in the ADC Reference Library as deprecated has been superseded and may become unsupported in the future. A technology identified as unsupported is no longer available from Apple for use by developers. Legacy documents help developers understand legacy technologies, identify replacements, and update their products to run on current Apple platforms.
