+### Notable changes
+
+#### The legacy HTTP parser is runtime deprecated
+
+The legacy HTTP parser, selected by the `--http-parser=legacy` command line
+option, is deprecated with the pending End-of-Life of Node.js 10.x (where it
+is the only HTTP parser implementation provided) at the end of April 2021. It
+will now warn on use but otherwise continue to function and may be removed in
+a future Node.js 12.x release.
+
+The default HTTP parser based on llhttp is not affected. By default it is
+stricter than the now deprecated legacy HTTP parser. If interoperability with
+HTTP implementations that send invalid HTTP headers is required, the HTTP
+parser can be started in a less secure mode with the
+[`--insecure-http-parser`](https://nodejs.org/docs/latest-v12.x/api/cli.html#cli_insecure_http_parser)
+command line option.
+
+Contributed by Beth Griggs [#37603](https://github.com/nodejs/node/pull/37603).
+
+#### ES Modules
+
+ES Modules are now considered stable.
+
+Contributed by Guy Bedford [#35781](https://github.com/nodejs/node/pull/35781)
+
+#### node-api
+
+Updated to node-api version 8 and added an experimental API to allow retrieval of the add-on file name.
+
+Contributed by Gabriel Schulhof [#37652](https://github.com/nodejs/node/pull/37652) and [#37195](https://github.com/nodejs/node/pull/37195).
+
+#### New API's to control code coverage data collection
+
+`v8.stopCoverage()` and `v8.takeCoverage()` have been added.
+
+Contributed by Joyee Cheung [#33807](https://github.com/nodejs/node/pull/33807).
+
+#### New API to monitor event loop utilization by Worker threads
+
+`worker.performance.eventLoopUtilization()` has been added.
