GD Prerelease/nightly builds

Can we get GD prerelease/nightly builds so those who want can test out new features?

If an important bug must be fixed, I usually release a “hotfix” a soon as possible.
In other cases, I try to release new versions when there are enough new features or bugfixes.

And anyway, I’ve not enough time to add tons of features each day, so I don’t think nighty builds are really needed.
