[binions]

I have read through the early, middle and late preflop sections in the 3rd edition. My observations of the changes:

3rd edition is 76 pages longer. Here are the additions:
Introduction + 5 pages
Limit sections +16 pages
Barry Tannenbaum's 10 common errors + 2 pages

The rest of the additional material resides in the 62 page SNG section, which contains some material ("Poker & Computers" and "Tournaments") that was in the Miscellaneous section of the 2nd edition.

Early Position
As for starting hands, Jones has tightened up and recommends more passive play in early position.

Tighter:
In early position unraised pots, he now says to fold QJs, JTs, A9s and 88/77 (these were calling hands in the 2nd edition). He now says to fold ATs and KQo until you are 3rd to act, and then he tells you to call with them.

In raised pots, he now recommends folding AJs and TT, where he recommended calling these in the 2nd edition.

More Passive:
In unraised pots, he recommends calling with KQs instead of raising (like he did before). Also, the text of the 3rd edition recommends calling with AJs, although the summary chart at the end of the chapter says to raise with AJs.

Changes in loose, passive games:
Borrowing a page from SSHE, he says if you expect 5-6 players to see the flop, then he now says you can call with any pair, even if the pot might be raised.

Middle Position
In middle position, Jones has a new section on a raise or fold philosophy when the pot hasn't been opened. He reiterates the "play any pair" philosophy if you expect 4-5 people to see the flop.

With big cards in middle position in an unraised pot, he now says to raise JTs. First, in he says to raise KJo and JTo (these were calling hands in the first edition). If limpers in front of you, he says call with KQo, AJo, ATo, KJo and JTo. Apparently, QJo is a folding hand since it is not mentioned.

For suited 1-gappers, J9s is the lowest playable (only with 4+ limpers). Compare T8s in the 2nd edition.

For suited kings, he now says KTs is as low as you go. In the second edition, K9-K7s were recommended in middle position.

When facing 3 bets cold, he now says to fold JJ.

When facing 1-3 limpers, he now says raise TT and above, and call 99-88. Earlier, it was raise 88 and above, and call 77-55. (Note, with 3 limpers + 2 blinds, you are getting 4.5 or 5:1 on your call. I would call with any pair after 3 limpers).

You are now supposed to fold J9s, T9s, 98s, KQo, KJo, QJo with 1-3 limpers in front.

QJs is totally missing from the middle position, 1-3 limper summary chart, while JTs is listed as both a raising and a calling hand. Me suspects a typo.

Against a raise, he now says to fold TT-99, except that you can play any pair in a raised pot if you are the 5th one in.

Late Position
He eliminates 65s, 54s, 86s, 75s, 96s, T7s, J8s, and Q9s.

He now recommends raising with medium pairs if you are the 6th one in.

Typo in the summary chart: says to raise 1-3 limpers with AA-TT, but call with 77. Text makes clear that he says raise with AA-88 in this case.

With 1-3 callers, you are supposed to now fold 66-55. These were calling hands in the previous edition.

With 1-3 callers, you are now not supposed to raise A9s, A9o and A8s, but you are supposed to raise JTs.

With 1-3 callers, you are now supposed to fold 87s-54s, T8s-75s, and K8s-K2s.

With 4 or more callers in front, you are now supposed to 65s-54s, 86s-53s, K8-K2s, and Qxs.

With a raise in front, you are now supposed to fold QJs and KJs unless it is going to be multiway.
