• Fixed an off-by-one error in mod.
• Fixed some constants not using #libdefine.
• Fixed additive blending not working in HUD Library when alpha is set to 1.0.
• ChangeFlag now support short flag names (e.g. "NOAUTOFIRE" instead of "WEAPON.NOAUTOFIRE"). Update decorate/changeflag.txt to use this. (Thanks to The Zombie Killer.)
• GetAspectRatio updated to a newer version.

1. Update decorate/changeflag.txt.
2. If you are using additive HudMessages in HUD Library, make sure that none of the non-additive messages in your mod became additive.

SendString!

• Added IsZandronum212()
• GetAspectRatio() now triggers a ProgramError when used serverside.
• Fixed ChangeFlag not working with INVENTORY.NOTELEPORTFREEZE.
• All internal functions now use ACSUtils_ prefix.
• Removed ScreenWidth(), ScreenHeight(), and AspectRatio().

1. Replace all uses of ScreenWidth() and ScreenHeight() with ZDoom functions GetScreenWidth and GetScreenHeight.
2. Replace all uses of AspectRatio() with IntDiv(GetScreenWidth(), GetScreenHeight()).

Widescreen support!

• Mouse cursor now supports widescreen!
• Added GetAspectRatio().

3. Review all uses of atoi() and atof().

Fixed duplicate actor warnings in changeflag.txt

No changes needed.

ChangeFlag, IsGZDoom, and improved cursor API! Thanks to The Zombie Killer for allowing ACS-X technologies to be included into ACSUtils!

This is a maintenance release that enables ACSUtils to be used in AOW-scale projects.
