The 1.3.x preview release will be up in a few more days, over coming weekend at the latest. I’m stomping more bugs than expected and making some last-minute improvements. This is also my busy time of year (end of financial year here in Australia) so I’ve got some heavy work on from all sides.
In the meantime, keep an eye on the Github page as I’ll be checking in code frequently leading up to first 1.3.x preview build.
I also want to offer a partial retraction regarding my earlier statement about the number of batches being 10x improved over previous version. This turns out to be highly variable based on the number of lights affecting objects, shadows, time of day, etc. The real figure is closer to 5-10x less. It’s still a great improvement, but I don’t want to mislead anyone if possible.
