Node.js 4.8.2 Release Brief

This is a special, expedited release for the Node.js 4 Maintenance line, which contains an important fix for a crypto-related memory leak introduced in the previous release.

This release also marks the transition of Node.js 4 into “Maintenance” mode as per the LTS plan. Expect fewer releases, only those for important regressions and critical security fixes.

Node.js 4 will be in Maintenance mode for one year. After that, Node.js 4 will hit End of Life. We recommend that you prepare applications and services to upgrade to Node 6 LTS within the next 6 months.

As with all releases within major version lines, minor and patch upgrades should be drop-in replacements for previous versions.

While not a routine or security release, if you're currently using Node.js 4.8.1 this release is important, as it resolves regressions in 4.8.1. If currently using 4.8.1, this is an important update. If using something prior to 4.8.1, this release has an otherwise normal update priority for the Node.js LTS and Maintenance release lines.

The NodeSource platform offers a high-definition view of the performance, security and behavior of Node.js applications and functions.
