Weapons that fire missiles (EXO-45 Patriot rockets, FAF-14 Spear, MLS-4X Commando, StA-X3 W.A.S.P., P-92 Warrant, P-33 Missile Pistol) fly at their missile's speeds, not the projectile's, so editing their velocity did nothing. Their velocity, drag and gravity rows are replaced by a Missile flight section: launch, cruise and minimum speed, acceleration and max flight time.
Lock-on missiles and the laser-guided Commando also get turn speeds, the angle past which a missile loses its target, and the guidance delay. The Patriot's rockets fly straight, so they don't get these rows.
The MS-11 Solo Silo lists the silo itself (health, armor, regeneration), its missile's stats and its missile flight. Not yet tested in a mission.
Grenade swap
Grenade launchers, grenade pistols, the One-Two's launcher and the Grenadier Battlement can fire a throwable grenade, Dynamite or a throwable mine (solo missions). Choose it with - / + (0 is the launcher's own round); edit the grenade itself on the Throwables tab (thanks nnikolajev, PR #40).
Backpacks
The Hover Pack has new rows: hover time while holding height and while climbing at full speed, hover speed, climb speed, climb acceleration and climb time limit. Rows the Hover Pack never reads are gone.
Jump Pack rows renamed to what they do: launch duration, boost after the launch.
Weapons
Move while reloading: an On/Off row for the weapons that hold you still while reloading (Autocannon, Spear, GL-28, Recoilless Rifle, Laser Cannon, Maxigun, MG-206, MG-43, Epoch, Airburst, W.A.S.P.).
M-1000 Maxigun: wind-up and wind-down times, and "Stops you while firing" On/Off (#42). The A/G-16 Gatling Sentry gets the wind-up rows too.
G-123 Thermite: burn time before it explodes (#38).
Weapon explosions that make an arc (GL-52 De-Escalator) get an Arc section: range, chain length and split, damage and status effect.
Projectile swap loads the source weapon's assets, so swapped projectiles keep their trails.
SG-20 Halt: swapping its stun rounds now holds (its ammo type attachments are written too).
W.A.S.P. and Warrant: damage shared by both firing modes is listed once, so editing one mode no longer silently changes the other (#35).
Settings
Several vehicles of a kind (on by default): a loadout can take more than one exosuit, FRV or tank.
Unlock unused items: adds items that are in the game files but the game doesn't offer: the M-104 Incinerator FRV (stratagem list), P-41 Ombudsman, G-11 Caltrops and LAS-22 Shear (armory).
Arc chain edits in multiplayer (on by default; not yet tested with other players): Off uses the game's arc chain length and split while other players are in the game, so arcs don't get stuck on screen (#41).
Panel bugfixes/improvements
Vehicle guns that never reload (exosuit arms, the Incinerator FRV's flamethrower) no longer show reload rows; giving them spare magazines crashed the game (#31).
Panel size, side, opacity and the remembered tab / weapon are read back after a restart again.
A Hover Pack recharge time of 0 no longer breaks its hover times, and values are never written as infinity.
A value saved for a row that no longer exists no longer marks the item as changed.
