This week’s Current release is a relatively small patch while we wait for the security fixes due next week. Some http fixes and an npm upgrade are the only notable things.

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

Notable Changes

• http:

  • When freeing the socket to be reused in keep-alive Agent, wait for both prefinish and end events. (Fedor Indutny) #7149
    • This is to prevent the next request from being written before the previous one has finished sending the body, leading to parser errors.
• npm: upgrade npm to 3.9.5 (Kat Marchán) #7139

    debugger: fix --debug-brk interaction with -e

    The command line flag `--debug-brk` was ignored when the `-e` flag was
    also present. This change allows the flags to both be honored when they
    are used in a single command line.

This is a regular and routine release for a Node.js Current release line. We will be sure to let you know when a release contains a critical update and a recommendation to upgrade. Of course, we'd love you to upgrade, but this release is not critical unless you are experiencing one of the issues identified and fixed above.
