CodeIgniter changes license to OSL 3.0?

Hello, I have read that CI is going to change its license to OSL 3.0, but, what does it mean? Will I have to license my software developed with CI under the same OSL? Could I develop non open source and non free software with CI?
Thank you in adavanced for your response!
