New Chinese visa regulations as from 01.07.2013

I already hold a 6 months F type one that will expire on 28.06.2013 and need to get a new one. Actually I am already in China as owner representative and soon I will be back home and must apply for a new one. Are there any substantial changes in the rules applicable with 01.07.2013? Here, in China, nobody knows yet what changes may be...
Thank you in advance for reply!
