OpenXcom requires a vanilla version of the original UFO: Enemy Unknown / X-COM: UFO Defense (any edition) with the latest patch. It is not compatible with other games in the X-COM series. If you don’t own a copy, you can buy it from one of these retailers.
Do not use modded versions of X-COM, as they may be incompatible with OpenXcom.
Check the Installation documentation for more details.
These builds are automatically generated from the codebase, so they have the latest fixes and updates as well as the latest bugs. Use these to try the latest features or check if a bug is obsolete. Do not install these on top of 1.0!

E2K: fixed build by MCST lcc compiler
MCST E2K (Elbrus 2000) - this is VLIW/EPIC architecture, like Intel Itanium (IA-64) architecture.
Ref: https://en.wikipedia.org/wiki/Elbrus_2000
e2k architecture has half native / half software support of most Intel/AMD SIMD
e.g. MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AES/AVX/AVX2 & 3DNow!/SSE4a/XOP/FMA4

fix statistics calculation for commendations
* woundsHealedTotal wasn't tallying totals
* killsWithCriteria<...> commendations were tallying results awkwardly, getting tallies for each OR criteria block separately from other blocks, which resulted in "best of" tallying across all OR blocks, rather than "total of" which was the presumed behavior by Commendations mod logic as well as other mods such as X-Piratez
