Until approved, you should consider that this package version doesn't even exist.
  • You cannot install this package under normal scenarios. See How to install package version under moderation for more information.

ost2 has passed automated validation. It may have or may still fail other checks like testing (verification).
NOTE: No required changes that the validator checks have been flagged! It is appreciated if you fix other items, but only Requirements will hold up a package version from approval. A human review could still turn up issues a computer may not easily find.

Guidelines

Guidelines are strong suggestions that improve the quality of a package version. These are considered something to fix for next time to increase the quality of the package. Over time Guidelines can become Requirements. A package version can be approved without addressing Guideline comments but will reduce the quality of the package.

  • In the Description element of the nuspec file a potentially invalid Url has been found. Recommendation is to fix this URL More...
  • Release Notes (releaseNotes) are a short description of changes in each version of a package. Please include releasenotes in the nuspec. NOTE: To prevent the need to continually update this field, providing a URL to an external list of Release Notes is perfectly acceptable. More...

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
