 As Node.js ships with npm, releases for the active lines will be made available shortly for your convenience. Please watch the [Node.js news feed](https://nodejs.org/en/blog/) for the following releases:
 
-* **v0.10 (Maintenance)**: Node.js v0.10.44 will include npm LTS v2.15.1. This is a major upgrade of npm from v1 which has previously been deprecated. No fix is being made available for npm v1, please upgrade to npm v2 as soon as possible.
-* **v0.12 (LTS)**: Node.js v0.12.13 will include npm LTS v2.15.1.
-* **v4 (LTS "Argon")**: Node.js v4.4.2 will include npm LTS v2.15.1.
-* **v5 (Stable)**: Node.js v5.10.0 will include npm v3.8.3.
+* **v0.10 (Maintenance)**: [Node.js v0.10.44](http://nodejs.org/en/blog/release/v0.10.44/) includes npm LTS v2.15.1. This is a major upgrade of npm from v1 which has previously been deprecated. No fix is being made available for npm v1, please upgrade to npm v2 as soon as possible.

+* **v5 (Stable)**: [Node.js v5.10.0](http://nodejs.org/en/blog/release/v5.10.0/) includes npm v3.8.3.

+**Update:** Unfortunately the version of npm that was bundled with Node.js version v0.10.44, v0.12.13 and v4.4.2 did not include the correct version string, `npm -v` reports `2.15.0`, however the code is v2.15.1.
 
 **Note that you can upgrade your installed version of npm manually** without requiring a Node.js update by using the command `npm install npm@2 -g` for npm LTS v2.15.2 or `npm install npm@3 -g` for npm v3.8.5.
