+- Now any TechnoType can be converted into any other TechnoType, no matter which category it belongs to, including to and from `BuildingType`s.
+  - This applies to every form of type conversion: warhead and superweapon `Convert` pairs, `Convert.Deploy`, `Convert.Undeploy`, `Convert.Health`, `Ammo.AutoConvertType`, `Convert.HumanToComputer` / `Convert.ComputerToHuman` and Ares' type conversion.
+  - If the new type is a `BuildingType`, it is placed on the spot the source techno stands on, as long as its whole foundation fits there. If it does not fit, the conversion does not happen; a deploy order for `Convert.Deploy` is refused with the `NoDeploy` cursor and the *Cannot deploy here* EVA.
+  - Infantry that deploy or undeploy into a type other than an infantry type first walk to the centre of the cell they are occupying, so the conversion animation is played in the middle of the cell.
+  - The new techno inherits the health percentage, veteran status, mind control, shields, invulnerability, attached effects, armor / firepower / speed multipliers and slave manager of the source techno. This also applies to vanilla `DeploysInto`, `UndeploysInto` and selling.
+  - `Convert.Direction` determines the direction the new techno faces when converting from a `BuildingType`. If not set, the new techno keeps the facing of the source.
+  - The building animations played while converting to or from a building are customizable with the following tags. Each of them can also be set in `[General]` to define its global default value.
+    - `Convert.ShowBuildupFrom` makes the building being converted play its sell animation instead of disappearing immediately. Requires the building to be sellable.
+    - `Convert.ShowBuildupTo` makes the newly created building play its buildup animation and plays `[AudioVisual] -> BuildingSlam` at its location instead of appearing finished right away. Requires `Buildup=` (the name of an SHP file) to be set for the new building type in `artmd.ini`.
