7.6 Release notes

edit

Client

edit

Support for Elasticsearch version 7.6.

Faraday migrated to 1.0

edit

We’re now using version 1.0 of Faraday:

The client initializer was modified but this should not disrupt final users at all, check this commit for more information.
Migrated error checking to remove the deprecated Faraday::Error namespace.
This change is not compatible with Typhoeus. The latest release is 1.3.1, but it’s still using the deprecated Faraday::Error namespace. This has been fixed on master, but the last release was November 6, 2018. Version 1.4.0 should be ok once it’s released.
Note: Faraday 1.0 drops official support for JRuby. It installs fine on the tests we run with JRuby in this repo, but it’s something we should pay attention to.

Reference: Upgrading - Faraday 1.0
