A bunch of minor fixes have accumulated in the past, I guess it’s been eight, months. These releases roll them up.
(Most of these fixes are already in Lectrote 1.3.9, recently released.)
The next release of these packages will rearrange everything into modern JavaScript modules, rather than the weird hybrid arrangement that’s accumulated over time. I will also try to improve support for running several VMs in the same Javascript context. (Dannii had a plan for this months ago, which I am finally following up on.)
