 Configure your AWS credentials and region environment variables for use in other

+GitHub Actions.
 
----
-
-### News
-
-We have recently released `v3` of Configure AWS Credentials! With this new
-release we have migrated the code to TypeScript, and have also migrated away
-from using `v2` of the JavaScript AWS SDK. This should eliminate the warning you
-have seen in your workflow logs about `v2` deprecation.
-
-In addition to the refactored codebase, we have also introduced some changes to
-existing functionality, added some new features, and fixed some bugs. These
-changes should be backwards compatible with your existing workflows.
-
-**Notable changes to existing functionality**
-
-- By default, the assumed role credentials will only be valid for one hour in
-_all_ use cases. This is changed from 6 hours in `v2`. You can adjust this value
-with the `role-duration-seconds` input.
-- By default, your account ID will not be masked in workflow logs. This was
-changed from being masked by default in the previous version. AWS does consider
-account IDs as sensitive information, so this change reflects that stance. You
-can revert to the old default and mask your account ID in workflow logs by
-setting the `mask-aws-account-id` input to `true`.
-
-**New features**
-
-- You can now configure retry settings in case your STS call fails. By default,
-we retry with exponential backoff twelve times. You can disable this behavior
-altogether by setting the `disable-retry` input to `true`, or you can configure
-the number of times the action will retry with the `retry-max-attempts` input.
-- You can now set the returned credentials as action step outputs. To do this,
-you can set the `output-credentials` prop to `true`.
-- There's now an option to clear the AWS-related environment variables at the
-start of the action. Clearing these variables is often a workaround for 
-problems, so enabling this can be helpful if existing credentials or environment
-variables are interfering with the action. You can enable this by setting the
-`unset-current-credentials` input to `true`.
-
-**Bug fixes**
-
-You can find a list of bugs that have been fixed in v3 in the
-[changelog](./changelog.md).

+This action implements the AWS JavaScript SDK credential resolution chain
+and exports session environment variables for your other Actions to use.
+Environment variable exports are detected by both the AWS SDKs and the AWS CLI
+for AWS API calls.
 
 ## Overview
+API calls to AWS need to be signed with credential information, so when you use
+one of the AWS SDKs or an AWS tool, you must provide it with AWS credentials and
+and AWS region. One way to do that in GitHub Actions is to use a repository
+secret with IAM credentials, but this doesn't follow [AWS security
+guidelines](https://docs.aws.amazon.com/IAM/latest/UserGuide/security-creds.html)
+on using long term credentials. Instead, we recommend that you use a long term
+credential or JWT to fetch a temporary credential, and use that with your tools
+instead. This GitHub Action facilitates just that.
+
+AWS SDKs and Tools look for your credentials in standardized environment
+variables. In essence, this Action runs through the standard [credential
+resolution flow](https://docs.aws.amazon.com/sdkref/latest/guide/standardized-credentials.html),
+and at the end, exports environment variables for you to use later.
+
 We support five methods for fetching credentials from AWS, but we recommend that
 you use GitHub's OIDC provider in conjunction with a configured AWS IAM
 Identity Provider endpoint.
 
-To do that, you would add the following step to your workflow:
-
-```yaml
-    - name: Configure AWS Credentials
-      uses: aws-actions/configure-aws-credentials@v3
-      with:
-        role-to-assume: arn:aws:iam::123456789100:role/my-github-actions-role
-        aws-region: us-east-2
-```
-This will cause the action to perform an [`AssumeRoleWithWebIdentity`](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html) call and
-return temporary security credentials for use by other steps in your workflow. In order for
-this to work, you'll need to preconfigure the IAM Identity Provider in your AWS account
-(see [Assuming a Role](#assuming-a-role) for details).
-
-You can use this action with the AWS CLI available in
-[GitHub's hosted virtual environments](https://help.github.com/en/actions/reference/software-installed-on-github-hosted-runners) or run this action multiple times
-to use different AWS accounts, regions, or IAM roles in the same GitHub Actions
-workflow. As an example, here is a complete workflow file that uploads artifacts
-to Amazon S3.
-
-```yaml
-jobs:
-  deploy:
-    name: Upload to Amazon S3
-    runs-on: ubuntu-latest
-    # These permissions are needed to interact with GitHub's OIDC Token endpoint.
-    permissions:
-      id-token: write

-        aws-region: us-east-1
-    - name: Copy files to the test website with the AWS CLI
-      run: |
-        aws s3 sync . s3://my-s3-test-website-bucket
-    - name: Configure AWS credentials from Production account
-      uses: aws-actions/configure-aws-credentials@v3
-      with:
-        role-to-assume: arn:aws:iam::222222222222:role/my-github-actions-role-prod
-        aws-region: us-west-2
-    - name: Copy files to the production website with the AWS CLI
-      run: |
-        aws s3 sync . s3://my-s3-prod-website-bucket

-For example, the URL that the OIDC JWT is issued from is different than the usual `tokens.actions.githubusercontent.com`, and will be unique to your enterprise server. As a result, you will need to configure this differently when you create the Identity Provider.

-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the

-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
