This is especially nice:
Item 50 - Expand minelaying control, allow mining of home ports.
Used Unload/Do Not Unload to control minelaying at destination. Minelayers may now mine home ports and/or make stops without mining. Minelyaing messages are generated if at least one side is under computer control.
NOTES:
1. When created or rearmed, minelaying TFs will have their minelaying control set to "Do Not Lay Mines". It must be manually set to "Lay Mines" when the player orders the TF to the location where it is to lay mines.
2. Minelaying TFs that were created prior to this update and that return to their home ports after this update will immediately reload mines and lay them in the home port. This is due to the unload/do not unload option being in the default (unload) condition. Once the upgraded game takes control of minelayers this will not happen.
