●Issue #1
The `AWS_USE_FIPS_ENDPOINT` and `AWS_USE_DUALSTACK_ENDPOINT` environment variables now only respect explicit `true` or `false` values for the S3 backend, replacing the previous behavior where any non-empty value was treated as `true`.
✓Solution
Ensure these environment variables are set explicitly to "true" or "false" if FIPS or DualStack endpoints are required.
Release Summary
This alpha release introduces Windows ARM64 builds, support for marking variables/outputs as deprecated, and the new `convert` function. It also includes numerous bug fixes across CLI, backend operations, and testing infrastructure.
