+This is a security release.
+
+Vulnerabilities fixed:
+
+* **CVE-2020-8277**: Denial of Service through DNS request (High). A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of service by getting the application to resolve a DNS record with a larger number of responses.
