@New content:
@Added stash tabs!
The stash now has 4 full tabs, each holding 80 slots, giving you a grand total of 320 slots to use - if you can afford it
Stash tabs are automatically added as you purchase more rows like before
You can move items between tabs freely, and the auto sort button sorts the current open tab only
@Added a new minimap system!
The default minimap now goes into the top right
It can be cycled into the overlays and hidden completely by pressing tab, or (B) on controllers
Added improved icons and minimap tiles for all areas
Shrines and loot of Unique or higher quality is now visible on the minimap
Minimap opacity setting can now go as low as 5% for the overlays
@You can now reset areas from the Waypoints in The Chronicon
Right click or press (X) with the controller on a selected area in the Waypoint menu and you'll get a confirmation window to reset it, giving you fresh spawns but maintaining the original layout
@Achievements:
Added an additional Achievement related to the stash
Changed the name and description of several Achievements
@Anomaly:
Changed many bosses to be more interesting and less punishing for melee characters
Music is now determined by area layout
Changed the portal sound
@Backwards compatibility and retroactive changes:
Further work has been done to simplify backwards compatibility and retroactive changes, meaning save files as old as from version 0.20.0 (July 2015) are still compatible with new enchants and such and will be adjusted accordingly
These changes will also affect the shared stash, from this update and forwards
@Balance:
Bonus experience gained from difficulty (and anomaly progression) is now exponential, which should smoothen the progression a bit when you get really far
Bonus exp from killstreaks now starts off at a higher rate but has diminishing returns with difficulty
Adjusted the very steep curve of bonus crystals from killstreaks to be a bit lower
@Bosses:
High Priest: Now Warps around a bit to be less static
High Priest: Boss area now has Shrines in it
@Companions:
Kills by companions now trigger "on kill" effects on the player (from both items and skills)
Companions now use the player's Overpower stat
@Enchants:
Special on hit effects such as chill damage, burn damage, etc has been rebalanced *heavily*
As such, all your items with these enchants have had their damage values adjusted, and the enchants unlocked, in case you no longer desire it
Added two new "on-hit" enchants:
Smite: Deals instant Holy damage
Blight: Deals shadow damage over time
@Interface:
Made the quantity numbers and key binding text on belt, skill bar, and inventory much smaller so it doesn't obstruct the actual thing in the slot
Removed "OEM" from many keybind characters
Killstreak bar is now yellow instead of a dark orange
Improved formatting of enchanting costs
@Items & Loot:
Special Unique equipment from Unique monsters, quests, and more, now roll random stats like any other item
Made keys a bit more rare
Magic Essence drop rate tweaked a bit
Potions no longer drop for lower tiers   
Added new Smite enchant as guaranteed roll on the following Templar items:
Ayeela's Guard
Soulpurger's Garment
Armor of Retribution
Added new Blight enchant as guaranteed roll on the following Warlock items:
Desecrator's Work
Death's List
@Monsters & Affixes:
Affixes:
Nova: Now uses actual nova spells rather than firing off projectiles in all directions, preventing insta-kills when too close
Blizzard: Now releases a Frost Nova on death instead of many projectiles, preventing insta-kills
Champions & Elite Packs:
Champions now prefer to use max ranks of skills, whereas Elite packs will generally use rank 1 of skills (such as the Nova affix skills)
Unique Monsters:
The Watcher: Replaced Ice Spear Nova spell with Frost Nova spell
@Misc:
Removed the shapeshift effect of Maddoc's Cure temporarily as it caused some issues with some skills
Shrines no longer activate the secret rude effect in Anomalies
Added some info on Companions to the Help Index
Damage number animations adjusted to better show crits
Pressing F10 will now save an image of the current tooltip displayed, such as an item card or skill card - this will help you in making guides and wiki entries etc
@Multiplayer:
Adjusted the exp penalties if players are on different levels - the exp gain reduction is not applied until there is a 10 levels difference of player1
@Performance:
Optimized redundant interface draw calls, slight performance bump for low end machines on interface updates
@Portals:
Now have an opening animation, and cannot be interacted with right away
@Respawning:
Respawn costs are now based on the value of your equipment, instead of your total crystals
In co-op, the cost is based on player 1's equipment
@Skills & Combat:
General:
Added target circles to several more skills when used by enemies
Thorns triggers now refresh killstreak duration by up to 2.5 seconds
Berserker:
Dragon Spikes: Now increases thorns by 220/260/300%, rather than adding set values

Condemnation: Now deals 120%/160%/200% damage (up from 50%/75%/100%)
Warden:
Nimbus: Increased range to 9 meters (from 7) and it now only casts the thunder spell when it's near a target, rather than at all times. Also added a slight idle movement to it & improved visuals somewhat.
