Changelog

Sourced from elasticsearch's changelog.

=== 16.7.2 (Nov 30 2020)

• use undefined as the default ssl ciphers to address a backwards-compatibility issue in node 15.3 nodejs/node#36292

=== 16.7.1 (Mar 26 2020)

=== 16.7.0 (Mar 25 2020)

• "7.6" is now the only apiVersion in the version 7 major version
