To me it seems no real change.

These are changes to 'ticketed points': (There may be more)

-AAA-xBBB-CCC when changed to -AAA-BBB-CCC (or -AAA-oBBB-CCC-).

-AAA-xBBB-CCC to -AAA-xBBB-xDDD-CCC-

-AAA-xBBB-CCC to -AAA-xDDD-CCC-

-AAA-BBB- to -AAA-xEEE-BBB

-AAA-BBB- to -FFF-CCC-

-AAA-BBB- to -AAA-GGG-
