I manually compared these 13 added licenses to the license-list-XML release notes for version 3.7 and 3.8 and confirm that they include all the added licenses. This PR’s additions don’t include two licenses/exceptions mentioned in those release notes, “GPL-3.0-linking-exception” and “GPL-3.0-linking-source-exception”, but those are exceptions, not licenses, so that’s fine.

If you were waiting for a third party’s approval, you have it. I think you can merge this and make a new release of spdx-license-ids.

(If you’re wondering how I found this PR and why I would care, I found this repo while trying to fix Yarn v1.22.4’s warning “License should be a valid SPDX license expression” for a license that was added in spdx-license-ids v3.0.5. I made local changes identical to yours before I noticed you already had a PR for it. I don’t personally care about any of the licenses in this PR, so no rush.)

@roryokane thanks for this comment. I'm updating spdx-exceptions now.

@shinnn spdx-exceptions@2.3.0 has the latest v3.8 SPDX data.
