I've just published Node-RED 3.1.10.
This is primarily a maintenance release - rolling up a number of recent bug fixes. Full details in the changelog.
Note that we are aware of deprecation warnings when you install this release - in fact, when you install any 3.x release. These are related to dependencies a few layers down in the dependency tree, on code paths we don't use. We cannot update these modules to remove the warnings as that requires major version bumps and dropping support for older versions of Node.js - something we won't do in the 3.x stream.
Thankfully, Node-RED 4.0 is just around the corner that will resolve them.
