Hi All,

We just released IUP version 3.31

There are few new features, but the changes are mainly bug fixes.

I'm sorry to say that IUP is on hold for now. It is not abandoned but its maintenance is restricted to bug fixes. The team has been allocated in another project and there is no time frame when it is going back to IUP.
