7.6 Release notes

edit

Client

edit
  • 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
edit

The client now supports API Key Authentication, check "Authentication" on the transport README for information on how to use it.

X-Opaque-Id Support
edit

The client now supports identifying running tasks with X-Opaque-Id. Check transport README for information on how to use X-Opaque-Id.

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
