Node v12.22.0 (LTS)

Notable changes

The legacy HTTP parser is runtime deprecated

The legacy HTTP parser, selected by the

command line
option, is deprecated with the pending End-of-Life of Node.js 10.x (where it
is the only HTTP parser implementation provided) at the end of April 2021. It
will now warn on use but otherwise continue to function and may be removed in
a future Node.js 12.x release.

The default HTTP parser based on llhttp is not affected. By default it is
stricter than the now deprecated legacy HTTP parser. If interoperability with
HTTP implementations that send invalid HTTP headers is required, the HTTP
parser can be started in a less secure mode with the

command line option.
