Releasing somewhat tested and stable VMs requires some work. The nightly builds work fine in general. We will make a next VM release for the next Squeak release as those usually happen close together. We use Squeak as a testbed for VM issues.
Here are the latest builds: https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/latest-build
If Cuis happens to be in dire need of a new official OSVM release, I am sure that we can work something out.
