It's been a while since Cyanogenmod released its Lollipop based ROMs with the title CM12. However, the tag synonym for cyanogenmod are still cm11 and cyanogenmod11. Shouldn't there be a new tag synonym named cm12 by now?
I've two questions (1, 2) that requires specifically the tag cm12 over tag cyanogenmod as an example. Also, if you see new questions under cyanogenmod you'll notice a lot of them at first page related to CM12 specifically.
