This next release is now nearly ready to go. There is one more non-trivial item to resolve before release: Fixing liquid rendering.

The AI re-work is finally complete and the code now makes far more sense so this can be tweaked and expanded more easily in the future.

Most of the low-hanging fruit in updating the clients is done, including this new sky and sunset behaviour (shown in the image).

I even managed to fix a long-standing lighting bug, which was now easier to observe with the lava behaviour (since lava is a light source but also an opaque block which flows as a liquid).

The problem with the fluid rendering is not new and was just a big oversight I noticed when testing lava behaviour: The horizontal "sides" of full flowing water are not rendered at all. The surface rendering done with the fluids looks good but the sides are just missing and always have been. This could be tricky but I suspect that it can be solved by composing the current surface renderer with the existing face builder used to minimize vertices in baked cuboids (since that _is_ what this what this problem is about, too).

Some investigation/experimentation required but this is nearing completion, at least.

Jeff.
