New release of Clojure lib for AWS presigned URLs & requests

The Clojure library aws-simple-sign was in pre-release for more than six months. With a modest download count of just above 2,000 and no reported issues, I finally found the time to promote the 2.0.0-alpha1 release of to a stable version.

For those unfamiliar with aws-simple-sign, it generates presigned URLs for S3 objects and signs HTTP requests for AWS.

The library is intended for those who for whatever reason want to avoid the com.amazonaws/aws-java-sdk-s3 Java dependency, or simply cannot use it (e.g., in Babashka).

A summary of changes in version 2.0.0 (since the previous stable release 1.6):

• No dependencies (no forced ones anyway).
• Improved documentation.
• Credentials resolution outsourced. You can do it manually, but most likely you want to use a “client” from either awyeah-api or Cognitect aws-api.
• “Container credential provider” supported (indirectly). Use one of the external “clients” when used in an environment that rotates credentials like: Amazon ECS or Amazon EKS.
• Minor API breakage 🫣 but for a more sane function signature with these new “clients”.
• Change license to MIT, and actually included the license now.

If you are using 2.0.0-alpha1, you can just update without breakage.

Enjoy 🚀
