I've had a quick look at the first half-dozen pages of recipes in my edition, and unfortunately it's not exactly the same - there are one or two recipes from the 2006 edition which don't appear to be in this edition, plus a number of new recipes that definitely aren't in the 2006 edition. Also, but of far lesser importance, the order of the recipes is slightly different in some cases.
On the back cover it states that there are over 75 new recipes in the metric (37th) edition - this is presumably relative to the 36th edition, which a quick Google search suggests was published in 2013; therefore it seems likely that there were further recipes beyond those 75 added in the editions published between 2006 and 2013.
