15559	Deprecated update_usermeta() and delete_usermeta() do not invalidate the correct caches	mdawaffe		"{{{update_usermeta()}}} and {{{delete_usermeta()}}} are deprecated, but do not invalidate the user's user_meta cache.

This can cause cache and even DB poisoning depending on how plugins using these functions work.

Attached uses the same cache invalidation that the new {{{update_user_meta()}}} and {{{delete_user_meta()}}} use:

{{{clean_user_cache( $user_id ); wp_cache_delete( $user_id, 'user_meta' );}}}"	defect (bug)	closed	normal	3.1	Cache	3.1	major	fixed	has-patch
