The following hooks occured in but do not occur in 2.5. Note that some of them may have been renamed, not removed. See below.
Important! Some WordPress hooks get applied in multiple PHP files. If you are trying to figure out what a specific WordPress hook does, sort the table by "hook" and make sure you are looking in all the files where it occurs.
Some hooks have variables in their names. For example,
admin_head- both have variable names. In general, any hook that ends (or begins) with
_, or contains a
$, has a variable name. Since the syntax with which these variables are defined may change from version to version, this page may think that a hook is deprecated (or new) even if it is not. You can usually catch this sort of thing by comparing this hook to the list of "related hooks" below.
