I'm working on converting an old 1.X extension over to EE 2.X, but my hook was 'submit_new_entry_end'. I can't seem to find a reference to what hook should replace it. My guess is 'entry_submission_absolute_end', but is that right?
I would assume so. Instead of asking yourself what hook replaces what hook, ask yourself if this describes the hook you need:
Additional processing after entry submission, after all processing, prior to redirect.
If so, entry_submission_absolute_end should be the hook you want :-)
You'll get the _entry_id, an array of meta data and an array of actual entry data, so you can do pretty much anything with it.
