I think the French Pléiade edition is a scholarly/critical edition? Montaigne himself said that the main changes between editions are additions. From On Vanity (Penguin translation): >I make additions but not corrections: firstly, that is because when a man has mortgaged his book to the world I find it reasonable that he should no longer have any rights over it. Let him put it better elsewhere if he can, not corrupt the work he has already sold. From such folk you should buy nothing until they are dead. Let them do their thinking properly before they publish. Who is making them hurry? My book is ever one: except that, to avoid the purchaser’s going away quite empty-handed when a new edition is brought out, I allow myself, since it is merely a piece of badly joined marquetry, to tack on some additional ornaments. That is no more than a little extra thrown in, which does not damn the original version but does lend some particular value to each subsequent one through some ambitious bit of precision. From this there can easily arise however some transposition of the chronological order, my tales finding their place not always by age but by opportuneness. Although I agree that a digital edition that allows you to toggle between the different editions would be a wonderful idea. Charles Rosen talked at length about the inadequacies of the Pléiade edition in this regard in his review[1].
