Shared Experience & Combat:
[..Fixed] many of the abuses of party combat - if a member of your party is killing things with wizardry, you'll get wizardry exp. If you don't have wizardry, you'll get some general exp, but you can't funnel it into things like alchemy anymore.
Readied Skills:
It is no longer required that a skill be in the ready_skill position to gain experience. Using the example above - if one player is using one-handed weapon skill to kill things and the the other player is using wizardry, both the players gain experience in the one-handed weapon and wizardry skills (assuming both have the skills in question, ortherwise they gain general exp.)
Total Experience:
The characters total experience is no longer related to the sum of experience in the players skills - A player could for example only of 1000 exp, but have skills with 2500 exp, 300 exp, etc. Removing the tie between skills and total experience allows for reasonable skill advancement - you can allow a player to easily get to level 20 in a skill without them now being level 20 player.
Experience Gain:
The experience one gets for a skill is greatly simplified. No longer is it weighted based on the stats of the player. Rather, the experience is based on what the skill was used for - opening a tough trap gets more exp than opening an easy trap. The stats the player has will improve the chances of success in most cases - this is bonus enough without also gaining additional experience.

Skill "Delay":
When certain skills are used, you may noticed a delay before the command is actually executed.
Casting Time:
Many spells when invoked or used now have a delay before the spell is executed.
