What's Fixed

s3_object_info — Duplicate Dictionary Fix

The s3_object_info module had an issue with duplicate dictionary entries in the returned data. This has been resolved, ensuring clean and accurate object metadata.

- name: Get S3 object information
  amazon.aws.s3_object_info:
    bucket_name: my-bucket
    object_name: data/export.csv
  register: s3_info
- name: Display object metadata
  ansible.builtin.debug:
    msg: >
      Object: {{ s3_info.object_info.object_name }}
      Size: {{ s3_info.object_info.content_length }} bytes
      Last modified: {{ s3_info.object_info.last_modified }}

autoscaling_group — Key Assignment Fix

The autoscaling_group module had issues with key assignments that could cause unexpected behavior during Auto Scaling Group updates. The fix improves reliability when managing scaling configurations.

- name: Create Auto Scaling Group
  amazon.aws.autoscaling_group:
    name: web-asg
    launch_template:
      launch_template_name: web-template
      version: "$Latest"
    min_size: 2
    max_size: 10
    desired_capacity: 4
    vpc_zone_identifier:
      - subnet-abc123
      - subnet-def456
    tags:
      - key: Environment
        value: production
        propagate_at_launch: true
  register: asg_result

kms_key — Reliability Improvements

The kms_key module received reliability improvements, making key management operations more consistent.

- name: Create KMS key for encryption
  amazon.aws.kms_key:
    alias: my-app-key
    description: "Encryption key for application data"
    key_usage: ENCRYPT_DECRYPT
    key_spec: SYMMETRIC_DEFAULT
    tags:
      Application: my-app
      Environment: production
  register: kms_result
- name: Display key ARN
  ansible.builtin.debug:
    msg: "KMS Key ARN: {{ kms_result.key_arn }}"

CloudFront Utilities — TypeError Fix

A TypeError in CloudFront module utilities has been fixed, improving stability when managing CloudFront distributions and related resources.

- name: Create CloudFront distribution
  amazon.aws.cloudfront_distribution:
    state: present
    origins:
      - id: myS3Origin
        domain_name: my-bucket.s3.amazonaws.com
        s3_origin_config:
          origin_access_identity: ""
    default_cache_behavior:
      target_origin_id: myS3Origin
      viewer_protocol_policy: redirect-to-https
      allowed_methods:
        items:
          - GET
