* Pick-up dropped weapons in-game (if usable by your class)

* Base weapon switch speed changed from 0.67 seconds to 0.5 seconds

Engineer
Increased base wrench construction speed on hit boost by 50%. Buildings now build 2.5x faster instead of just 2x (additive of 1.5x + base speed)
Gunslinger / Minisentry
* Mini Sentries can now be repaired
* Mini Sentries can now be wrench construction boosted

Soldier
Cow Mangler 5000
* Removed: Cannot be Crit boosted
* Granted/earned Crits (e.g. Kritzkrieg) will be converted to Mini-Crits instead
Equalizer and Escape Plan
* Changed no healing penalty to 90% less healing from Medics while active

Spy
* Max speed increased to 320 (from 300)
* Changing to a new disguise while already under a disguise takes 0.5 seconds instead of the normal disguise time of 2 seconds
* In the disguise menu, pressing 'reload' will also toggle the disguise team.
* While invisible, Spy receives 20% less damage from all damage sources
* While invisible, Spy has reduced timer on debuffs (fire, jarate, milk, bleed)
* Decreased the damage penalty on Sentries sapped by the Spy from -66% to -33% (i.e. shooting a Sentry the Spy sapped with a Revolver is now more effective)

Pyro
All Flamethrowers
* Added: Direct damage reduces Medi Gun healing and resist shield effects by 25%
* Medics hear a "healing interrupted" sound when this is happening to their heal target
Airblast
* Hit detection for both players and projectiles is now a consistent cone
* Aiming at a player's feet no longer misses!
* Airblasting players now factors in the momentum of the Pyro and target, giving both more control over the interaction
* The target's existing velocity is no longer cancelled
* Players moving at the Pyro at great speed will be reflected away at great speed
* Players moving towards/away from the Pyro will experience less/more push force
* Airblast now causes target player to have reduced footing and air control for a short period
* No longer a flat stun
* Now factors in the upward angle of the airblast, rather than having a fixed upward force
* Total push force slightly increased

Medic
* Base
All Mediguns allow the Medic to match the speed of their heal target
* Medics now have slightly higher health regeneration when healing a hurt patient
Crusader's Crossbow
* Healing a player with an arrow now grants a small amount of ÜberCharge
* Ubercharge gain rate reduced in the same way that the Medigun's healing (and therefore, Ubercharge build rate) is - based on the last time the target was in combat
* Reduced by a third when 1 - 10 seconds outside of combat, and scales up to normal over 10 - 15 seconds

Heavy
All Miniguns
* Changes:
* The 1-second damage and accuracy penalty now applies to the first second of spun-up time, whether or not the Heavy is firing. Previously, the 1-second damage penalty would only be removed after 1 second of firing.
