Deprecated notice warning

I am trying to figure out how to get rid of the deprecated warnings in the elgg 1.8. I have a bunch of plugins that probably have some API that is deprecated, and now warnings are displayed all over the place.

I've turned off all my debug settings, and it still continues to appear.

Screen shot here:

The warning says:
Deprecated in 1.7: extend_view() was deprecated by elgg_extend_view()!

Please help !

Thanks in advance.
