Old style GMs versus new style

babydontforget

I just received a bunch of NIP GMs. Some of them have a logo where "good" is red/pink and bigger, and others have logos where "goodmama" is all in black. Based on pictures form the flickr page, it seems as though the former is newer.

1) Am I correct that the red/pink "good" logo indicates the newer style of goodmama? Meaning, did the change in logo correspond with the switch from the "old style" to the "new style"?

2) What changes were made with the new style? A higher rise, right? What else?
