Fable...
I am referring to the Permanent Potions that you create yourself using the Alchemy skill 'Extract'.
Having actually tried it, I can assure you my information is correct.
As to the 'Huge number of bugs fixed' - I have just gone from using 1.4 to using 1.42, with no other changes, and a number of problems and bugs I had have now gone away.
My observations are thus based on my own personal experience.
