There have been updates to the functionality, such as e-prescribing medications, but it is dependant on the version of Epic your organization is using. You need to be up on the 2010 version (currently the newest version) to have access to e-prescribing. The 2010 version also offers organizations a bit more flexability as far as what data displays in reports and some other minor enhancments.
If youre itching to e-rx, go bug your IT dept and tell them to upgrade!! ;)
Hope that helps
