The Nuvie team have been busy adding still yet more support for Martian Dreams to said cross-platform engine, and they have also been doing some bug-fixing on the recently-added TMX export feature, and elsewhere.

2015-01-25 Malignant Manor r2000
* Fix crash when using dithering in original+ styles larger than 320×200
* Use any hat on a joystick/gamepad instead of only hat 0.
* Fix joystick axis naming in auto-generated cfg.

2015-02-02 Eric Fry r2001
* Fixed some object rendering issues with the TMX map export.
Fountains should display over the pools in U6 now.

Their current focus, as far as expanding support for Martian Dreams is concerned, seems to be on the mining/drilling/ore loading portion of the game:

2015-02-15 Eric Fry r2002
* Added support for automatic pushing of railcar and drill objects in MD
* Added the ability to move MD rail car and drill objects in and out of mines.
* Added optional boolean flag to lua map_get_obj() function. This allows you
to include multi-tile objects in the search results if they are on an adjacent
overlapping tile.
* Added the ability to exclude an object from ObjManager::get_obj()
* Added player_before_move_action() script call. This can be used to execute lua script
before the player is moved. This is used by the MD push object logic.
* Added MD use switch bar logic.
* Added support for lua script based move-code logic.
* Added movecode for MD drill and rail car objects.

2015-02-17 Eric Fry r2003
* Added MD use assembled drill.
* Started on MD use shovel on ore to container logic.

2015-02-18 Eric Fry r2004
* More work on MD use shovel on ore to container logic.

2015-02-20 Eric Fry r2005
* Work on MD usecode to unload dirt/ore from containers.

As always, this team impresses with the speed at which it is able to operate.
