OPA v1.0.1 was created to address CVEs in the Go runtime. OPA typically removes the manual download links for the vulnerable version in the website as well. Example in the picture below. Would recommend we keep the versioning consistent to how OPA has the versions displayed on their website, leaving off vulnerable versions.

Same behavior as v1.0.0 no functional issues with ScubaGear when running with v1.0.1.

Had issues personally with my terminal on one client hanging when trying to do the hash verification. No issues on another client. I chalk that up to isolated client issues.
