Certain router log fields and router HTTP headers deprecated

Change effective on 26 March 2013

queue and wait fields have been removed from router log messages. Also, the Heroku router no longer sets X-Heroku-Dynos-In-Use, X-Heroku-Queue-Depth and X-Heroku-Queue-Wait-Time HTTP headers for incoming requests.

See the HTTP Routing article for details.
