DUB 1.0.0 is nearing completion. The new feature over 0.9.25 is support for single-file packages, which can be used to write shebang-style scripts on Posix systems:

#!/usr/bin/env dub
/++ dub.sdl:
    name "colortest"
    dependency "color" version="~>0.0.3"
+/

void main()
{
    import std.stdio : writefln;
    import std.experimental.color.conv;
    import std.experimental.color.hsx;
    import std.experimental.color.rgb;

    auto yellow = RGB!("rgb", float)(1.0, 1.0, 0.0);
    writefln("Yellow in HSV: %s", yellow.convertColor!(HSV!()));
}

With chmod +x it can then simply be run as ./colortest.d.

Apart from that, the release contains some bug fixes, most notably it doesn't query the registry for each build any more.
