Anyone else seeing:

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. in /forums/bb-includes/classes.php on line 260

…after upgrading to 2.2? I can’t figure out what’s going on.

There is a trac ticket started for it already:

https://trac.bbpress.org/ticket/649

It’s just a warning though, not an error. Display of warnings on a production server should be turned off. If this is from your logs, then it’s not a big deal and someone will address the trac ticket.
