Refer to mountainproject.com for current updates. FA Jeff Mahoney has been busy since last year, putting up three new excellent additions. All routes range from 5.8 to 5.10a/b.
There are many new routes being developed all over. It's impossible for me to use Mountain Project as my source of information.
If you have specific information on those routes you may add it to the "additions & corrections" of the Rocky Top page.
