New features with update 1.3.3

[asuser]

Hello, I would like to ask how to use the new features with the update to 1.3.3.

1. New features can be seen in the editor and in the "properties" file, among others, compared to the previous version. How does it work?:

RevealAction
MoveAction
StrikeAction
ForcedMarchAction
ReserveAction
TriggerAction
DiscardfEquipmentAction

2. New "Vision Variables" have also been introduced in the "properties" file:
Clear, Fog, Shroud
How can the variable "Shroud" be used with the editor, the previous hex marking tile "Shroud" was ineffective according to my tests (a friendly/enemy unit located in this hex area should/could be "invisible")?

3. New unit traits have also been introduced. Which functions does this support?
NavalTorpedo
AoE1

4. New achievements may also be important for all players on the steam platform. Will new achievements be introduced for the 1943 DLC?

NavalTorpedo looks like something from Pacific. They must have finished part of their work already.

One of the dev diary screens for that already has it shown as an example of an ability on a plane.
