buildkite/agent v3.111.0 on GitHub

v3.111.0 (2025-11-05)

Warning

If you use a custom S3 bucket for artifacts, this applies to you.

As part of updating to AWS Go SDK v2, the "credential chain" for providing
authentication credentials to access artifacts in custom S3 buckets, is now
more standard. The existing BUILDKITE_S3_ env vars are still available and
take precedence, but when these are not set, the AWS-default mechanisms are
used as provided by the SDK, with as few customisations as possible.

This means additional ways to pass credentials to the AWS S3 client may be
accepted, and where multiple credentials are available, the precedence may
have changed (to match what the AWS SDK expects by default).

Because of this, and the number of combinations of different ways to provide
credentials, this change may inadvertently break pipelines using custom S3
buckets for artifacts. Please reach out to support@buildkite.com or raise
issues in GitHub if this impacts you!
