Change to HTTP decoder

[epeeler]

Did I miss a notice that the http decoder was being changed so that most of my rules based on the web-browsing app would break?  Nearly all of my web-browsing traffic is suddenly being identified as unknown-tcp.

I notice in the release notes for 646 app update that the http decoder was modified.

With every content update a release note email is sent out if you opted in from your support account

But the behavior you describe does not sound "as expected" so something possibly went wrong, maybe the content package installation failed in the backend
Have you tried rolling back, redownloading and reinstalling?
