Work in progress (WIP) means its not complete.
The latest VTE release is not final, our development continues even though we do not plan on releasing for ArmA anymore (we will release for ArmA 2).
IF YOU DO NOT AGREE WITH THIS, PLEASE DELETE THE VTE RELEASE IMMEDIATELY. NOBODY FORCES YOU TO USE THIS VERSION, IF YOU DO, ITS YOUR OWN CHOICE. THANK YOU.
Whole purpose of this page is to let users know what they are getting into, this is very WIP version, if you are scared of placeholder stuff and issues, just stay away from this release, please.
Please post any feedback you got, for example bug reports. See more details from bug reports page.
All in all you'll find VTE to be very enjoyable, we wouldn't release it otherwise :)
