Oregon chains that will be discontinued

[Chainsaw Pete]

I've been reading the Oregon Maint. and Safety Manual and discovered that they are discontinuing the following chains: 72lgx; 72jgx;

Are the replacements as I've shown below? I'm guessing by looking at the Manual.
72lgx Powercut > 72EXL PowerCut
72jgx Powercut > 72EXJ PowerCut

So this is mostly a nomenclature change? See below

It is old news there must be threads and videos from two years back. Exl has features on the drive link wiggly indentations.
