Several folks have inquired about a Pathfinder-compatible version of our popular Behind the Spells: Compendium pdf. I suspected there would be little to update and, indeed, was proven correct as I combed through the book today. 99% of the work is compatible already but, of course, there's always a couple things that need attention due to some minor changes from 3.5 to Pathfinder. Thus, I decided that I would simply post the "errata" to make the Compendium Pathfinder-compatible right here...
Dispel Magic: remove the "Area Dispel" section from the second spell secret
Shield: replace the Strength check with the combat maneuver bonus when attempting the bull rush for the first spell secret
Web: replace the Strength checks with combat maneuver bonuses (the DC for these and Escape Artist checks is the DC of the spell)
Wish/Limited Wish: ignore the spell secrets dealing with XP
Aside from these fixes, you must also account for skill changes such as Spot = Perception, Decipher Script = Linguistics, etc. These are seldom encountered as most skill checks in the book deal with Spellcraft and Knowledge.
That's it! Now, you needn't hesitate in picking up BtS: Compendium to bring your spellcaster up to full potential.
