whatsold is an utility for MATLAB developers. It informs about functions which are or will be obsolete. Developers could run this utility at each new MATLAB release to change MATLAB codes accordingly for upward compatibility.

You may also run the official MathWorks function *whatsnew* which displays the Releases notes.

whatsold displays in Command Window the functions which :

- will be removed in a future release

- will become obsolete

- will not be supported

- are no longer supported, deprecated or obsolete

- have been removed

- are undocumented or Internal use only (for geek purposes)

The screenshot has been made in R2010b. It shows for example which functions will be removed in a future release.
