@mdorf, this PR is necessary to resolve a critical vulnerability in rack 1. Unit tests pass so would it be safe to merge?

@mdorf, this PR is necessary to resolve a critical vulnerability in rack 1. Unit tests pass so would it be safe to merge?

Rack is already unpinned and using Rack 2 in production, it was done here https://github.com/ncbo/ontologies_linked_data/commit/3eda8225168e9924b6e943deacf9f67465e555e6;

So this PR is obsolete and can be closed.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
