full patch notes below, taken from the runic forums:

GRAPHICS
*Intel HD graphics cards should not show ghosting/smearing effects if shadows are enabled

PERFORMANCE
*LARGE performance optimization to buff/debuff bar displays when there are a large number of overlapping, nonexclusive effects (damage over time, and duration based effects or knockback )

SKILLS
*Shield Bash bonus damage now deals the stated amount(charged and uncharged)
*Wolfpack will properly strike turrets
*Bonuses due to proximity now always expire properly
*Damage bonuses/reductions for Battle Rage properly expire
*Fixed Critical Hit bonuses on some effects not properly incorporating bonuses to crit
*Pet damage bonuses are applied to effects

LEVELS
*Three Sisters zone now has an appropriate level range for proper NG+ reward scaling
*Various issues resolved in Luminous Arena in multiplayer
*Level determinism fixed (Was broken with precacheing in previous patch - could result in triggerable elements and some structural elements re-randomizing on load, or in multiplayer)

ITEMS
*Set reward for Inquisitor set altered to a functional bonus
*Fixes to the summon skull proc on equipment (prevents it from spawning exactly on a target)
*Effects based on proximate monsters now work properly with socketables
*DOTs were not properly attributing experience if the effect was applied from an item instead of a skill

MISC
*Target Dummy is Charm resistant
*Fixed issue where rebinding Close All Menus could lock you in pause mode
*Fix for shift-click casting a left-click spell and then selecting an item (would previously auto-attack)
*Pet enhancing bonuses work more consistently for pets attached to OTHER pets
