Our tests pass, but are there any incompatible changes between this version and the old version? They have different major version numbers. I realize that there is a vulnerability report for all but this version of the library, but I'm wondering if it could break user programs to upgrade.

They have different major version numbers.

I don't think so, the v2 is older than the commit that we were pinning

• https://github.com/emicklei/go-restful/releases/tag/2.0.0
• emicklei/go-restful@ff4f55a

Am I missing something?

[nsrip-dd]

I think the version this PR upgrades to is newer: https://github.com/emicklei/go-restful/releases/tag/v2.16.0

But, I'm mainly just being paranoid :D I compared the two versions and didn't see any incompatible API changes. Thanks!

Thanks for the extra 👀 - appreciate it!
