+## 2020-04-07, Version 10.20.0 'Dubnium' (LTS), @BethGriggs
+
+### macOS package notarization and a change in builder configuration
+
+The macOS binaries for this release, and future 10.x releases, are now
+being compiled on macOS 10.15 (Catalina) with Xcode 11 to support
+package notarization, a requirement for installing .pkg files on macOS
+10.15 and later. Previous builds of Node.js 10.x were compiled on macOS
+10.10 (Yosemite) with a minimum deployment target of macOS 10.7 (Lion).
+As binaries are still being compiled to support a minimum of macOS 10.7
+(Lion) we do not anticipate this having a negative impact on Node.js 
+10.x users with older versions of macOS.
+
