 - New `AEmitter` and `PEmitter` INI and Lua (R/W) property `PlayBurstSound` which denotes whether the BurstSound should play when appropriate. This should not be confused for a trigger - it's just a enable/disable toggle to avoid having to remove and add BurstSound altogether.
 
+- New `GameActivity` INI properties `TeamNTechSwitchEnabled` which determine whether activity team factions are configurable by the user. This is most useful for communicating what the player is not intended to change, or what inputs would be ignored otherwise.
+
 - Allow lua scripts to use LuaJIT's BitOp module (see https://bitop.luajit.org/api.html)

 - The `LimbPath` property `NormalTravelSpeed` has been renamed to just `TravelSpeed`.
 
+- `GameActivity` INI properties `TeamNTech` values switched to lazy eval, allowing them to be validated once all modules are loaded.
+	As well, the scenario menu activity configuration screen now respects defaults set in INI, where possible.
+
+- Internal GUI element `ComboBox` no longer displays dropdown combobutton when disabled, to communicate visually that it's setting is not modifiable.
+
 - Almost all ctrl+* special inputs functionality (i.e restarting activity, world dumps, showing performance stats) are now mapped to right alt, to not interfere with default crouching inputs. The only exception is ctrl+arrow keys for changing console size.
 
 - Gibs and detached Attachables now inherit the parent's angular velocity, as well as velocity derived from the angular velocity of the parent MO and their offset from the parent's centre. On gibs, this is scaled by `InheritsVel`.
