+### v 0.1.5 (these and older changes by @jamespizzurro)
+
+* All NPCs are now much more aware of spawnable props so that enemy NPCs will attack them upon encountering them, including if they are blocking the way to players
+* Players can no longer collide with each other, thereby fixing any issues where players could get stuck inside other players when spawning and whatnot
+* Support NPCs and deployed turrets no longer damage players' spawned props
+* The RPG is now an equipment item rather than a primary weapon
+* S.L.A.M. tripmines can no longer be set off by players, support NPCs, deployed turrets, or spawnable props
+* Zombie and headcrab waves have now been combined into one zombie wave, where headcrabs have been re-added to all zombie types and have the possibility of releasing from their hosts
+* NPCs that wield weapons (e.g. Combine soldiers and armed citizens) can no longer fire from insanely far distances, making them less effective overall
+* Reworked the number of NPCs that spawn per wave based on more logical factors and additional play-testing (we used maths!), where players are now expected to progress further in the game overall (i.e. players will likely clear more waves per game now compared to the old system)
+* Added a new weapon for the equipment slot: the vortex hopwire grenade
+* Added challenge waves, where only one random type of NPC is spawned during the entire duration of the wave, that occur every 5 waves by default (this can be changed via ConVar by servers though)
+* Fixed all known issues pertaining to contingency_bunker
+* Fixed all known issues pertaining to contingency_factory
+* Fixed all known issues pertaining to contingency_overpass
+* The maximum health of spawnable props is now shown on the prop spawning menu and the current health of a particular spawned prop is now shown when you put your crosshair over it
+* There is now a 'teleport back to spawn' function that can be bound to a specific key ('m' by default), but it can only be used when you are truly stuck on something
+* Players can no longer spawn props in ways that get them, other players or support NPCs directly stuck inside said props
+* Completely revamped contingency_ravine from scratch
+* Added a concrete barrier to the prop spawning menu (costs 10 credits, has 200HP)
