No, /shout became an emote command like eg /cry or /dance. /chat replaces the old /shout command.
Nite, maybe you could ask Ddhanna nicely to compile you a client/server package.

Not a lot of new stuff anyway... new targeting system, new combat system, removal of stats such as strength, con, removal of skill groups (agility, physique, etc), new NPC interface system, account system, ability to use spaces in character names...

Lot of broken stuff mostly, like the new tutorial island... not even fully finished yet and it will need a remake already (mostly the explanation stuff), due to all the changed stuff. Sigh. Not looking forward to rewriting all that documentation...
