Use of logical AND assignment operator `&&=` breaks compatibility with node 14.x

[jacobq]

I know Node.js v14.x is ancient, but I have an old (large) project that still uses it and one of its dependencies was depending on version ^6.10.4 of ml-matrix, and the package manager rightly tried to use 6.12.1, and then everything broke. Is there a list of node.js versions supported by this package somewhere? I would have expected a change that drops compatibility with a runtime to be a semver major bump release (e.g., 7.0.0).

Please consider making your supported platforms explicit (or show me where the list is, in case I just missed it).
