Future is Bright sun shadows have been live for about a month and a half, yes. The following things listed as “On Track” on the roadmap are also live (I am sure of this now):
Localization – Auto-Capture Date & Time Detection
Improved Character Importer
Advanced Terrain Tools – Heightmap (this came out earlier this week)
Here are the announcement threads for 3 of those (Future is Bright, Character Importer, and Terrain Tools):
As for the new localization tools, there has been no announcement thread for it yet. However, you can see it is listed as “Live” in the most recent release notes (it also seems I was wrong and that they are not shipping in tandem with each other):
I’m unsure if the other 2 localization features have shipped already, but I do not believe they have.
Edit: @UnderMyWheel pointed out that one of the other localization features is pending release according to those same release notes. I must have missed it.
