Node.js 4.7.3 Release Brief

Node.js 4.7.3 is exclusively a security release, with an update to OpenSSL 1.0.2k. While the OpenSSL team have said this is at most a moderate update, the Node.js Crypto team (Ben Noordhuis, Shigeki Ohtsu and Fedor Indutny) have determined that the impact of the OpenSSL vulnerability is low. You can learn more about the details of how they came to this conclusion on the Node.js blog.

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


This release contains only 7 commits, all of which are part of the upgrade to OpenSSL @ 1.0.2k.

    deps: copy all openssl header files to include dir

    All symlink files in `deps/openssl/openssl/include/openssl/`
    are removed and replaced with real header files to avoid
    issues on Windows. Two files of opensslconf.h in crypto and
    include dir are replaced to refer config/opensslconf.h.
