Changelog for patch 1.65 / GOG-13 (Windows) (added 16 September 2016):

- This update is for Windows only.
- Miss shots should no longer go through walls; the trajectory code has been updated so they should only hit tiles that a "hit" shot would be able to hit.
- Grenade scatter calculation updated, so "miss" throws can actually miss by a meaningful amount. This applies to both Xenonauts and aliens throwing grenades.
- Stunned zombies (which appear dead) will no longer spawn zombies. This will eliminate the bug where Reapers apparently spawn from thin air, and occasionally were also invulnerable for reasons that remain unclear
- Damage from base defence turrets now correctly reduces the number of attacking aliens it fails to destroy an attacking UFO.
- Soldiers now gain Bravery from taking suppression damage, as it was virtually impossible to train up before.
- Soldier Strength now updates correctly, as there was a bug in the formula before.
- Manufacturing screen now displays the number of required items in your stores when previewing a project, rather than just the number of required items.
- Saviour Medal and Crux Solaris medals can now be awarded and displayed correctly.
- Alien bases are now correctly destroyed if you blow the Cores and then suffer a squadwipe.
- Fixed an issue in the air combat where the aircraft throttles would sometimes not work properly.
- Geoscape performance has been optimised on some systems.
- Game startup speed has been improved.
- Fixed crash when a building collapses with a drone inside.
- Minor revisions to game manual.
