PANORAMA

• HUD

• Added a red glow behind the progress bar and health numbers when health is critical.

• Fixed armor progress bar to no longer flash when you lose health.

• Health over three digits will now scale down to fit appropriately and no longer clip.

• Sharpened the transition times in the weapon selection HUD to reduce delay in displaying player’s equipment.

• Fixed grenades not disappearing from weapon selection immediately after throwing them.

• Improved the dropped bomb and planted bomb rings on the radar.

• Fixed the kill panel string when a player is killed by fire.

• Matchmaking

• Wingman can now be remembered as the last played game mode for the next time a user plays online.

• Fixed the beginning of match to correctly distinguish between “waiting for players” and “warmup” state in Wingman.

• Fixed rank and skill group data appearing on community servers.

• End of match will now share mouse rather than capture all mouse input, which fixes mouse key bindings when match ends.

• Fixed not being able to toggle the spectator player panel’s visibility by pressing the key bound to “drop” (G by default).
