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

2017/04/02 ------------------ NOTES v0.975 ----------------------

- drastically reduced cratering effect on most weapons

--- effects / visuals

- added a simple concrete-style ground decal below buildings
- fixed an issue with 3d model faces not being rendered on some ships on spring 103.0

--- AI

- renamed "Onslaught" mode AI to "Brutal"

2017/03/12 ------------------ NOTES v0.974 ----------------------

--- balance / mechanics

- morphed commanders take 50% longer to repair
- increased the total repair cost from 66% to 90% of the unit's energy cost
- increased commanders' power rating by 50%, this means that when commanders fight normal units:
a) they take 50% longer to get the same amount of experience
b) the normal units gain experience 50% faster
(this won't change commander vs commander interactions)

- changed minor speed upgrade bonus from 4% to 5%
- changed major speed upgrade bonus from 8% to 10%

- level 2 robot, vehicle, aircraft and ship factories can now build some of the level 1 units of the corresponding type

- made collision volumes grow vertically as the unit gets built (prevents an exploit where "nearly empty" build frames could block projectiles)

- updated the fortification wall build tooltips to correctly show that they have 4800 HP
- reduced fortification wall height slightly
- increased cost of wall sections from 50 to 65 metal

--- effects / visuals

- increased model size and improved the trails of advanced missiles

--- UI / widgets

- updated sort order on factories' build menu : start with construction units, then from cheapest to most expensive (roughly)
- added N hotkey for build menu pages
- added gadget to prevent players from getting stuck in FPS mode
- modified clock and fps indicator
