I'm replying here to a recurrent question I'm receiving in my email box.
Yes DGH is still active and its last version (2.1) is compatible with LC 8.x. Plus, we done good tests with LC 9.x as well to say DGH is also compatible with this version.
We are not really active on our own forum, but be assured DGH will be updated if necessary to support the future LiveCode versions.
By the way, in October we have added a new Lessons for DGH, so yes DGH is definitely alive! Spread the word!
