************************** PATCH NOTES ****************************

2017/05/03 ------------------ NOTES v0.976 ----------------------

--- balance / mechanics

- slightly increased CLAW "Maul"'s damage per second and cost
- reduced inaccuracy of GEAR "Dominator Form" commander's cannons

- fixed collision volumes for many units, mainly for robots which had volumes shorter than their actual height
- fixed a serious issue introduced in 0.974 that made SPHERE shielded units' collision volume flat when shields were down
- fixed GEAR "Toaster"'s collision volume and aim point inconsistency when under construction

- teams with all players disconnected are automatically resigned unless they have at least 40% as much value in units as the strongest team
(requirement is doubled if all their commanders are dead)
- when a player resigns their commander explodes

- GEAR Heatray towers no longer try to turn their turret while firing

--- effects / visuals

- added thruster exhaust effects for all aircraft (added LUPS system by jK)

- made the ground decal below metal extractors fade faster after they're destroyed

- reduced the transparency on projectiles from some weapons, namely EMG
- AVEN Dervish, Magnum and Racer had their "Plasma Cannon" weapons changed to "Plasma Bolt", with different impact sound and projectile
- added trail for long range plasma cannon shots
- modified rocket trails for better consistency, and to make smaller rockets less expensive in terms of performance
- made fire area effects simpler to make them less expensive in terms of performance

--- UI / widgets

- system messages are no longer shown on a separate message box (to avoid wasting space)
- improved handling of multiline messages

- added bloom shader widget (by Kloot) : maybe makes game look better (adds blur/glow) but comes with a performance cost
(experimental : it's disabled by default, can be enabled through the widgets menu - F11 key)

- show awards for players when the game ends

--- other

- cleanup of deprecated weapon definition tags and categories that caused warnings on the infolog.txt
