Heroes

 * Fixed Waveform vision.
 * Fixed Power Cogs from pulling in allied units.
 * Fixed Life Drain instantly filling pugna's life when used on illusions.
 * Fixed Amplify Damage on mechanical units
 * Fixed Corrosive Skin to happen at the start of the attack animation rather than at the end of
 * Fixed Morph Replicate illusion being able to lose its identity if it gets cycloned

Gameplay

 * Some Fog of War fixes.
 * Fixed a lot of pathing issues around towers
 * Fixed some selection issues with flying courier
 * Fixed a bug where characters who had model changes (such as Tiny when using Grow) would not have their selection boxes updated to match the new model.
 * Matchmaking is undergoing some development in the coming weeks, so games may take a little longer to fill (up to 5 minutes).
 * Fixed channeled abilities getting immediately interrupted if you gave an order to the unit while the unit was in the channeled ability's cast animation. The order will now be followed once the channel completes.
 * Now if you give an attack or move order to multiple units, any units in your selection that are currently channeling will wait for the channel to complete before executing the order, instead of interrupting the channel to execute the order immediately.
 * Fixed some spells with projectile dodging due to invisibility
 * You can now target-cast cast-attacks while disarmed (e.g. Frost Arrows while under Frost Bite).
 * Fixed gold values to stay at max instead of looping back to 0.
 * Fixed neutral selection issues

Visuals

 * Fixed animations set while the unit was dormant not properly being transmited to the client
 * Changed how we do flying z-deltas, we now smoothly interpolate both up and down.
 * Lowered the flying height somewhat.
 * After a delay, heroes now sink under the ground.

UI

 * You can now select which region you want to matchmake under
 * Shop tab reorganization. Main shop split into basics and upgrades, subtabs below that for individual pages.
 * You can now buy items with hotkeys. Invoking the shop with the shift key held down opens it in hotkey mode. Regular mode does not respond to or display hotkeys.
 * Alt+Key binds are now supported.
 * Fixed not being able to query units by clicking on them while spectating a game.
 * Fixed a case where the quick buy sticky slot showed the wrong purchasable state.
 * Fixed an exploit with using Disassemble on Illusion inventory items
 * Removed arbitrary lines in the healthbar art, now ticks will draw clearer.
 * 1000 mark tick now draws slightly thicker than 250 mark.
 * Inventory items can show 0 charges, eg urn of shadows.

AUDIO
 * Fixed respawn music not properly starting at the correct time on dedicated servers.
 * Added battle music.
 * Added explore music.

MISC
 * Fixed crash on exit.
 * Fixed server crash that happens if you tried to toggle your Ring of Basilius when its aura had been purged/removed (aura is also no longer purgeable).

BOTS }}
 * Fixed bug that was causing Radiant-side bot pathfinding to be incorrect.
 * Cleaned up how lanes are selected by bots. They each now specify an affinity for the middle lane or the better-farming lane, and will handle human players in lanes better.
 * Bots can now still jostle for lane assignments in the first 30 seconds of a game.
 * Bots can now switch lanes when defending rather than locking onto the first one they decide to defend.
 * Bots now care more about defending buildings close to their base.
 * Made bots less concerned about their own self-preservation when they have a bunch of allied heroes around.
 * When pushing a lane that they're not in, bots now consider the lead building's backdoor protection status when deciding where to go.
 * Adjusted the retreat position to make sure it's inside the fountain aura range.
 * Reworked Roam to more closely match the desire-scoring scheme that the other abilities use. Bots will roam a bit more often now (maybe a bit too often), but will do so at smarter times towards smarter targets.
 * Made bots close faster on a target when a roaming hero arrives.
 * Fixed bug that would almost always prevent Sniper from roaming early-game.
 * Fixed bug that would sometimes cause bots to stand still when trying to defend a tower with lots of creeps nearby.
 * Fixed end-of-bot-game server crash.
 * Made bots slightly more likely to attack each other in 1v1 situations.
