[Oldbies: What's changed around SL in the decade since ~2007?]

Invisiprims!  Oh man I remember those.  Absolutely essential for giant robot avs way back when.  The alpha av layer sounds really nice!

[Oldbies: What's changed around SL in the decade since ~2007?]

I blundered into the SL subreddit quite by accident and it reminded me of the great 2004-2007 period in which I was really active in SL.  Worked on a bunch of contracts to Nissan USA, CSI:NY, Reuters, etc. on their regions via the Electric Sheep Company.  I'm sure all that stuff is all completely gone now.  I imagine the Prokofy Nevas, Anshe Chungs, Cubey Terras and most of the other oldbies are long vanished.  The hours I spent on IRC...  Nostalgia!

So, what's truly new across the grid?  I logged back on for a few minutes just now and to my utter surprise, my LSL-based items still actually worked fine after a decade.  That's actually impressive.  What new features and resident dynamics are around these days?
