Buildkite Release notes and new features

Elastic CI Stack v7 is here with Buildkite Agent v4

Elastic CI Stack for AWS v7 is now available, bringing Buildkite Agent v4 to both Linux and Windows instances. Agent v4 clears out functionality deprecated since v3 arrived in 2018 and makes supported behavior the default. New capabilities have continued shipping in v3, so for most setups the move changes nothing about how you use the agent.
