12 Deprecated Functions

This appendix lists currently deprecated functionality along with how to replace it.

Starting in Stan 2.29, deprecated functions with drop in replacements (such as the renaming of get_lp or multiply_log) will be removed 3 versions later e.g., functions deprecated in Stan 2.20 will be removed in Stan 2.23 and placed in Removed Functions. The Stan compiler can automatically update these on the behalf of the user.
