I just started to upgrade code to 4.14 and immediately found that half of the classes I search for no longer exist in the CHM API reference, despite still existing in the codebase. This is classes that were documented previously.
If I search for them in the online documentation, the page comes up but is clearly a reference from a previous engine version.
This is making it much harder to bring code up-to-date.
Examples that are missing:
FConstraintInstance
UPhysicsConstraintComponent
UPhysicsHandleComponent
UInputComponent
Basically, a whole lot…
