We've just published new releases for both 5.x and 4.x versions of Node-RED.
Node-RED 5.0.8 includes a number of fixes from a wide range of new first time contributors - thank you to everyone for getting involved. We've also updated a number of dependencies to pick up security related fixes.
Node-RED 4.1.16 just contains the dependency updates.
The 5.0.8 docker images are already published, the 4.1.16 ones are still building as I type.
It should be resolved in the next maintenance release. The upstream component that was broken has very recently published a fix for it. There's a bit of work for us to do to get it incorporated, but that should happen in the next week.
Docker builds all done and available at the usual places (Docker Hub and GitHub).
The Docker 4.1.x builds did manage to uncover a Docker Buildx bug that should hopefully be fixed by the next time we have to spin a version, which should make builds quicker.
