🐛 Fixed

Stop cache invalidation from deleting a cache entry that another job has just saved again by @ss1909 in buildkite/agent#4442

Title replayed output "Cache exec saved" instead of "Cache hit saved" when buildkite-agent cache exec skips a command by @ss1909 in buildkite/agent#4462
Skip the upload in buildkite-agent cache save when the cache store already has an identical archive by @buildkate in buildkite/agent#4463

Upgrading

Follow the v7 upgrade guide before updating. Remove or replace retired parameters in parameter files and deployment automation. If you use a custom AMI through ImageId or ImageIdParameter, rebuild it from the v7 base AMI and update it in the same stack update; a v6-based AMI might not boot under the v7 template depending on the configuration.

Perform a CloudFormation stack update with the following URL:

https://s3.amazonaws.com/buildkite-aws-stack/v7.4.0/aws-stack.yml

If you want to launch a new stack, you can use this link (make sure not to use your production AWS account, create a new one for CI):
