And I kept old version anyway, so if problem I downgrade. However, it's
really better now and I can see my photo very fast.

I did not test the whole part, it seems working fine to me, that doesn't
mean it'll work in all cases. However, it's really worth to test it,
dcraw has really improved since 8.60

What did change ?

-a the desc changed, but it seems the same feature
-A -r -/+M -C are new option, no compatibility problem
-H it adds a new value to recover more, old values still work.

I really think you can upgrade to dcraw 8.76 without any risk at all.
But I agree with you that it's better to use a dedicated and validated
version of dcraw as options available seem change a lot between 2
different versions.
