In addition there is also now a notch filter with adjustable bandwidth which can be applied by right clicking in the new AF (Audio Frequency) mode of the waterfall.

To use with the RTL-SDR, you will need to download the file, run install.bat and then manually un-comment the line in the SDRSharp.exe.config text file and then copy over rtlsdr.dll and libusb-1.0.dll from an SDR# installation that was installed using the Quickstart guide method.

You can follow the development of this modified SDR# on the SDRSharp Yahoo group, and specifically in this Yahoo Groups thread.
