it's an off course incomplete list of changes need to be done in engine.

It adds a bit more engine/default/modules/boot/dialogs translations

Dynamic zones can now be set to reload lists instead of saving them, using zone.embed_lists
In developer mode all generated maps' entities are now checked for upvalues. Beware evil code! Beware!

Simplified main menu's new game option, with dev mode on it always shows a list of modules, without it only shows if more than one is installed

This is for use in movement effects that bypass actually having to follow via normal walking so they don't home in on players that break LOS too quickly.

This let you ask for less accuracy on things like teleporting to the target when its out of LOS.

Savefiles now contain a "last_log.txt" which contains the last 2000 lines of well .. log. This is the actual game log, not the ingame message log.
