Please report suspected vulnerabilities through a private GitHub security advisory. Do not include sensitive details in a public Issue.

During coordinated trials, the stable release currently identified by npm's latest tag receives security fixes. A different version under the approval-gated next tag is supported only for its explicitly named release-specific qualification; it does not displace the stable release before separate promotion approval. When next and latest identify the same version, that release fills both roles.

Distribution channels are independent of version syntax. Before 1.0.0, increasing the minor version starts a breaking compatibility line; increasing the patch version is otherwise backward-compatible within that line. All other older ordinary versions, historical prereleases, and unreleased source snapshots are not supported unless a separate support policy says otherwise. Historical prereleases remain outside the ordinary version compatibility guarantee.
