2018/05/27 ------------------ NOTES v0.996 ----------------------

--- balance / mechanics

- units with weapons with an AOE edge effectiveness boosts got a bit cheaper
(5-10% cost reduction on GEAR Grenado, CLAW Nucleus, Massacre and Mega, and AVEN Stasis and Tsunami)

- increased the base economy from 6 M/s and 60 E/s to 8 M/s and 80 E/s
(this is meant to give a bit more slack for players who want to do something other than rushing expansion)

- reduced energy cost of repairing damage from 100% to 75% of the unit's energy cost

- air transports fly higher and change altitude faster

- SPHERE flying spheres now use the smoothed air mesh to avoid bumping into cliffs

- air mesh should follow the ground height profile more closely
(this means on maps with high hills aircraft will not climb so high unless they're closer to the cliffs)

- aircraft no longer try to fly below the altitude of the lowest metal spot
(relevant for maps where disputed ground is on high plateaus delimited by steep cliffs)

--- UI / visuals

- tooltip over empty ground shows altitude instead of ground speed modifier (was always x1)

2018/04/26 ------------------ NOTES v0.995 ----------------------

- fixed warnings that showed up when building SPHERE geothermal powerplant

- fix issue with name not appearing over AI players' commanders

- fixed issue which caused flying spheres and some aircraft to move weirdly due to collisions with the factory after construction finishes

- improved wreckage of SPHERE "Trax" and GEAR "Box"

- changed some of the sounds for the SPHERE and CLAW commanders and many vehicles

2018/04/24 ------------------ NOTES v0.994 ----------------------

--- new units

- AVEN "Tsunami" : Heavy Riot Hovercraft

- GEAR "Luminator" : Long Range Heavy Fire Support Robot
- GEAR "Land Mine" : perimeter defense

- CLAW "Dynamo" : Mobile Anti-Armor Energy Ring Launcher
(charges and shoots a very powerful ring that can pierce through multiple enemies, but charging can be interrupted by enemy fire)

--- balance / mechanics

- AVEN "Bass" : reload time and damage halved, to make it more consistent. It's projectiles now show a cool space distortion effect
- AVEN "Excalibur" : reduced HP by 25% and cost by 12%. Modified model to look "slimmer"
- AVEN "Swatter" : reduced HP by 25%, changed armor type from L to M and adjusted cost
- AVEN "Talon" : reduced speed by 20%, increased HP by 20% and reduced bomb reload time from 9s to 6s and adjusted cost

- GEAR "Titan" : increased HP from 7500 to 8000 and adjusted cost
- GEAR "Flareon": turret rotates to keep firing direction to compensate for the body rotation, if necessary

- CLAW "Gyro" charge disruption threshold lowered to 25% damage taken within 3 seconds instead of 1 second

- SPHERE "Magnetar" : increase passive regeneration from 160HP/s to 250HP/s
- SPHERE "Nimbus" : missile and rocket have 600 range

- increased the damage dealt by GEAR and SPHERE long range plasma cannons and reduced HP by about 15%
(to make them more cost effective at their core role, which is long range bombardment)

- Major regeneration upgrade adds +2HP/s in addition to the 0.2%HP bonus
- Commander regeneration upgrade adds +20HP/s instead of 15HP/s

--- UI / visuals

- slightly improved some of the models, textures and walk cycles

- made unit status bars slightly bigger and easier to read
- GEAR heat rays now have a more dynamic texture
- improved the appearance of the commander name tags (widget from Balanced Annihilation, by Floris and Bluestone)
- tooltip shows different label and damage color for disruptor/paralyzer weapons
