Blizzard have announced that the Overwatch hero McCree will be renamed and they will no longer be using developer names for the game's characters. This follows Overwatch developer Jesse McCree being let go from the company, without a specific reason being given, which happened amidst the Activision Blizzard lawsuit situation unfolding.
Here is the full statement from the Overwatch twitter:

You can now play Overwatch for free until January 4th, and even buy the game permanently for 25-50% off! There's also the Winter Wonderland event currently active until January 5th to check out as well, with new skins and activities to be had.

Today's PTR brings a lot of Hero tweaks and will be a pretty large download when it goes live, as it's a remaster. We're getting changes to D.Va, Orisa, Roadhog, Sigma, Winston, Baptiste, Lucio, Mercy, Moira, Doomfist, Sombra, Symmetra and Tracer, of varying significance.

HERO UPDATES
Sigma
Kinetic Grasp
Can now be cancelled by Accretion. Experimental Barrier
Can now be recalled while Kinetic Grasp or Accretion are in use. BUG FIXES
General
Placement previews should now be much smoother (Reaper Shadowstep, Mei Ice Wall, etc). Placement previews will now hold their position after clicking, until they’ve been confirmed by the server. Fixed a bug where first person animations sometimes wouldn’t play when abilities were used immediately after being frozen. Fixed a bug where orientation toggles for placements could flicker at higher latencies (Ice Wall, Amplification Matrix, Photon Barrier). Workshop - ‘Set Max Health’ now functions as intended. Heroes
Reinhardt
Fixed a bug that caused charge knockback to be applied multiple times. Sigma
Accretion now correctly deals half damage to self. Accretion projectile no longer gets destroyed when impacting Symmetra turrets. Gravitic Flux can now move Pharah during Rocket Barrage. Fixed a bug where victims of Gravitic Flux could get stuck on slippery rooftops. Fixed a bug where Gravitic Flux would fail to work on Dropship doors. Fixed a bug that allowed Sigma to avoid an enemy’s Gravitic Flux effect by activating his ultimate. Fixed a bug that allowed Sigma to retain some of his movement ability when he was incapacitated (stunned, slept, etc) during his Gravitic Flux. Fixed a bug which caused Gravitic Flux to not be cancelled if you switch to another hero while it is active. Sombra
Fixed a bug where Sombra couldn’t gain ultimate charge for one second after EMP hack auras end on targets. Wrecking Ball
Fixed a bug that could cause Wrecking Ball to be temporarily stuck when using Piledriver on a slippery terrain.
