    update to go1.24.7

    update to go1.24.7 This includes 1 security fix: - net/http: CrossOriginProtection bypass patterns are over-broad When passing patterns to CrossOriginProtection.AddInsecureBypassPattern, requests that would have redirected to those patterns (e.g. without a trailing slash) were also exempted, which might be unexpected.
