elasticsearch-transport 7.6.0

on Ruby Gems

Client

• Support for Elasticsearch version 7.6.
• Last release supporting Ruby 2.4. Ruby 2.4 has reached it's end of life and no more security updates will be provided, users are suggested to update to a newer version of Ruby.

API Key Support

X-Opaque-Id Support

Faraday migrated to 1.0

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
