2019/10/06 ------------------ NOTES v1.17 ----------------------

--- Balance / Mechanics

- about 2% cost reduction in units with bursty L damage weapons and relatively low dmg/s, namely light missile launchers
(as a side effect there's also a slight reduction on cost of buildings that explode violently when destroyed)

- increased collision sizes for various flying spheres, namely "Comet", so they're less likely to dodge heavy cannons and rockets

- morphed commanders' wreckages metal amount reduced to 500 from 1000 (same as basic forms)

--- Sounds

- modified sounds fx volume to fade out more with distance and to make weapon sounds relatively louder than other sounds
- modified "arrived" sounds for some units to be more quiet and lower pitched
- modified unit sounds for several aircraft, AVEN and GEAR robots

--- UI

- fixed CLAW "Flail"'s build picture
- settings widget enforces hardware mouse cursor mode
- scale the font sizes up to make text more readable on 1440p and higher resolutions
- added minimap events widget to signal when units are damaged

2019/09/24 ------------------ NOTES v1.16 ----------------------

--- Engine

- changed the recommended engine from "104.0.1-1382-gc0c48fc maintenance" to "104.0.1-1404-g47794d1 maintenance" or later
(lobby clients should auto-download the correct version after joining the nebula hosts on the official server)

--- Balance / Mechanics

- made GEAR "Reaper" use smooth aiming

- fixed CLAW "Hazard" and AVEN "Raptor" rockets diving into the ground when firing at higher targets

- reverted building's collision volume growth to always cover their footprint and fixed being able to stack construction towers in some situations

- fixed AVEN "Turbulence" not firing from the main rocket turret (oops)

- fixed AVEN "Bass" firing too early (before reaching the proper aim alignment)

- fixed AVEN "Ghost" decloaking while flying over water

- CLAW "Flail" now has two shotguns instead of shotgun/cannon. Slightly increased is range and energy cost to fire.
- AVEN "Stalker" side missile launchers are replaced with higher dps light lasers with same range as the main weapon.
(these help make the units role clearer and avoid aiming issues)

- SPHERE "Moth" has slightly improved maneuverability, dmg/s, aiming tolerance and projectile turn rate but reduced projectile speed
(it should be much less likely to miss nearby targets)

--- Sounds

- made unit selection and movement sounds more noticeable (they've been too muted on the latest versions unless the player zooms in)
(use +/- to adjust global volume ingame)
- added distinctive sounds for CLAW and SPHERE robots and commanders
- added generic "tap" sound for area metal extractor and line formation movement orders

--- UI

- adjusted icon for GEAR "Heater" and "Cube" robots, AVEN "Albatross", Zephyr and various radar/jammer units
- settings widget enforces "grounddetail" and "icon distance"
(to avoid people with default values not seeing icons or having visually distorted map height profile when zooming out)

--- Animations / Visuals

- slightly improved textures on several CLAW robots
