3.0.8 struct and function name changes

I was surprised to find two changes in 3.0.8 which effect C module developers; config_items within the rad_request structure was renamed to config fr_connection_pool_delete was renamed to fr_connection_pool_free I thought 3.0.7 had been tagged as stable and thus the variable and function names were locked to allow developers to migrate. For me this was not a problem, but it is worrying as it makes it more difficult to convince people with their own modules to migrate off of 2.x. Thus I am curious as to if this was a leak from 3.1.x where such changes should be expected? Or is 3.0.8 really the first stable release of 3.0.x and the previous update to the web site was in preparation for it? Geoff
