Changelog for Internal Update (19 October 2020):

- added D-Pad support
- fixed DirectDraw and slowdown problems on some systems

Standalone installer updated: 1.0 ⇒ 1.0 hotfix.

A really great changelog would be if GOG would just unlock Jackal for us.

Doubtful, considering no ones ever unlocked it, it seems like it was never meant to be unlocked.

Hopefully they tweak this release just a little more - still seems to have random hiccups throughout gameplay, but is certainly much more playable for me with this new update (and d-pad support!).
