@Loot:
Bags should now drop more frequently
Reduced drop rates of consumables somewhat
Tweaked drop rates of magical items - scaled too much with Magic Find & difficulty bonuses
Unique and Legendary now start dropping on level 10
Rings and Amulets now start dropping on level 10
Rare items now start dropping on level 5
**Note that exceptions to these drop rules apply to unique monster drops and quest rewards
Dropping a stack of items no longer fills the entire screen with items, but only throws out a single one containing the full stack
Keys are now more rare
Challenge scrolls should drop more frequently
Added 4 new unique items dropping from select unique monsters across the 3 acts
Old ones have been updated with more interesting enchants or stronger enchants
@New item enchants:
Phasewalk (Boots, allows walking through objects and monsters unhindered)
Sludge (Boots, poison trail)
Ironsole (Boots, immune to spike trap damage)
@Stats:
Health on hit and Mana on hit now restore more the larger the damage dealt compared to your based damage, so for example crits and hard hitting skills will restore much more
(As such, I also had to lower the maximum roll on items quite a bit, so you'll probably only get lower rolls from now on, but overall it should feel better - let me know!)
Magic Find stat now also reduces the chance of getting items used by other classes (note that Unique and higher is never found for a different class, regardless of Magic Find stat)
@Skills:
Movement skills such as dodge roll and tumble will now break any breakable objects in your path
Improved targeting of skills, you should now always target roughly the center of foes, this is especially noticable on large and flying monsters
Lowered the mana cost of most low-mid tier Berserker and Templar skills
@Interface:
The item type and slot text is no longer in the same color as the item's quality, making it more distinct
Added a better image for the off-hand slot
Screenshakes tweaked & smoothed - no longer shakes on critical hits
Added option to hide player nametag
Added option to hide monster affixes
Added option to hide status effect notices like "Slowed!", "Paralyzed!" etc, and made them less intrusive
Added some edge wrapping to the inventory when using gamepad
Items that are part of a set will now display all slots of all parts of the set, so you know what to look for
Made the quest indicators on NPC's and items (! and ?) more clear
Enemy healthbars no longer go offscreen at the top of the screen
Added some larger windowed resolutions to the options
Increased the maximum scaling setting of all text, tags, and interface options up to 400%
@World:
Lowered the amount of spike traps spawning by quite a bit
Reduced the number of spiderlings spawning from eggs, and made them "pop" out a bit
Reduced the number of spider eggs in The Old Tunnels, The Spider Cavern, and the Infested Cellar
Added many new possible affixes for the Unstable Dimension area
Unstable dimensions are now also more rare
Update the Chronicon a little
Added a new Personal Stash! This stash is directly tied to your character and has 50 slots
Added 6 new bosses to the challenge areas
Challenge area bosses are now much stronger!
@Monsters:
Unique monsters are now much more balanced with difficulties and levels
Unique monsters are generally more dangerous and should be considered mini-bosses
Tweaked health growth on some of the tankier enemies, making them less tanky on lower levels
Reduced experience gained from minion & summoned monsters as it was disproportionate to regular monsters
Some newer monsters had their experience values tweaked (for instance Gargoyles had it increased quite a bit)
Monsters dropping the special challenge scrolls are now called "<name> The Challenger" to make it more clear
@Misc:
Tweaked controller vibrations, should now line up better with the amount of screenshake going on (less vibrations in general)
Companions can now pick up money and mana/health pickups for you. They will not actively seek them out, but in case they get close to them they'll grab them. (They have the same pickup radius as you have)

Possible fix for blank save files upon PC crash, let me know if you get this bug.. really need to fix that
 *I have a permanent fix for this ready, however it relies on functions broken for people with non-english windows logons, so I cannot deploy it yet as it would make these people unable to even save :(
