What does HD mean on a 45-150 Lumix zoom?

I have a 45-150mm f/4-5.6 zoom that came originally with my GX7. On the barrel it is designated as 'HD'. Back in the day, DPReview carried a news item announcing that various lenses had been upgraded to HD status. This was one of them.

When I look at this lens as currently offered new (e.g. at B&H), there is no HD marking.

What does HD mean? Does it make any difference? Is the fact that it seems to have disappeared of any significance?
