In August, we made a lot of progress on backend code updates... and, we also had some holidays 🏖️

Here's the more in-depth version of what the team worked on, in our regular engineering update.

What's the best way to transform a 256 colour image to a 64 colour one where the second 32 colours are the same as the first 32 except with half the RGB values and I don't want to use dithering? Someone must have done a good one for Amiga EHB mode at some point but I am having no joy whatsoever in finding one, and I am not good enough at colour theory to know how to work sensibly within that constraint
