@ -22,6 +22,8 @@ Version 1.3.1+svn:
* new [own_village] condition to check if someone own a particular village
* new [store_villages] tag to store village locations
* all [store_*] tags get a default variable name
* use complex variable substitution almost everywhere
* new key for [set_variable], literal=, to avoid variable substitution
* Misceleanous bug fixes
* a unit that dies while attacking will now correctly play it's own death
