Notable Changes

Deprecations and Removals

• [7dd2f41c73] - (SEMVER-MAJOR) module: runtime deprecate exports double slash maps (Guy Bedford) #44495
• [ada2d053ae] - (SEMVER-MAJOR) process: runtime deprecate coercion to integer in process.exit() (Daeyeon Jeong) #44711

HTTP(S)/1.1 KeepAlive by default

Starting with this release, Node.js sets keepAlive to true by default. This means that any outgoing HTTP(s) connection will automatically use HTTP 1.1 Keep-Alive. The default waiting window is 5 seconds. Enable keep-alive will deliver better throughput as connections are reused by default.

Additionally the agent is now able to parse the response Keep-Alive which the servers might send. This header instructs the client on how much to stay connected. On the other side, the Node.js HTTP server will now automatically disconnect idle clients (which are using HTTP Keep-Alive to reuse the connection) when close() is invoked).

Node.js HTTP(S)/1.1 requests may experience a better throughput/performance by default.

Contributed by Paolo Insogna in #43522

DTrace/SystemTap/ETW Support were removed

The main reason is the lack of resources from Node.js team. The complexity to keep the support up-to-date has been proved not worth it without a clear plan to support those tools. Hence, an issue was raised in the Node.js repository to assess a better support, for DTrace in specific.
