Does the latest Scofield Reference Bible delete or substantially alter any of the original notes?

There's some controversy about differences between the original Scofield reference bible and the latest editions, which were edited by a committee after Dr Scofield's death. I'm wondering whether any of Scofield's original notes have been modified or deleted, and if so which ones and to what extent? Or is the new edition just an "amplification" of the original which adds more notes and maps and etc, but leaves the original text as it was?
