When I was watching the first gameplay of the 0.23, I noticed that there were some new parts (other than the space lab) in the science... bits, parts, sector... (forgot the word). Did you notice that or was it my imagination? Unfortunately I just had the chance to see the first 20 minutes. Also, I like the fact that they added a bar showing you exactly how much monoprop there is in the kerbal backpack, instead of just percents.
