AWS SimSpace Weaver versions

We continuously improve AWS SimSpace Weaver. You must download the latest SimSpace Weaver app SDK when we release a new version if you want to take advantage of new features and feature updates. To run an existing simulation with a newer version, you might have to update its schema and code, then start a new instance of the simulation. You don't have to upgrade, and can continue to run existing simulations with previous versions. You can check this page to see what's different between the versions. All versions are currently supported.

Important

The latest version of the AWS SimSpace Weaver User Guide only covers the latest version of the service. You can find the documentation for previous versions in the AWS SimSpace Weaver Guide Catalog, available from the main documentation landing page.

Latest version

The latest version is: 1.17.0

How to find your current version

If you created a simulation with the SimSpace Weaver app SDK, the create-project script downloaded a version of the SDK libraries into a subdrectory in your sdk-folder. The subdirectory that contains the SDK libraries has a name that includes the SDK version number: SimSpaceWeaverAppSdk-sdk-version. For example, the libraries for version 1.16.0 are in SimSpaceWeaverAppSdk-1.16.0.

You can also find the version of the SimSpace Weaver app SDK distributable package in the text file app_sdk_distributable_version.txt in your sdk-folder.

Download the latest version

Use one of the following links to download the latest version.

You can also download the complete SimSpace Weaver app SDK distributable package from the SimSpace Weaver console in the AWS Management Console. Choose Download app SDK from the navigation pane.

Warning

Don't use the AWS CLI to download anything that appears to be the SimSpace Weaver app SDK distributable package. Only use the download links on this page or the download link in the console. Any other download method or location isn't supported and might contain obsolete, incorrect, or malicious code.

Troubleshooting app SDK downloads

We use Amazon CloudFront (CloudFront) to distribute the app SDK .zip files. You might experience some of the following situations.

  • The downloaded package isn't the latest version

    • If the .zip file that you downloaded doesn't contain the latest version, it's possible that the cache at your CloudFront edge location hasn't updated yet. Download again after 24 hours.

  • You get a HTTP 4xx or 5xx error using a download link

    • Try again after 24 hours. If you get the same error, use the Feedback link at the bottom of the SimSpace Weaver console to report the problem. Select Report an issue as the Type of feedback.

  • Your browser reports that it can't load the page

    • You might have a local network or browser configuration problem. Verify that you can load other pages. Clear your browser cache and try again. Make sure that you don't have firewall rules that might block the download URL.

  • You get an error when you try to save the file

    • Check your local file system permissions to make sure that you have the correct permissions to save the file.

  • Your browser displays AccessDenied

    • If you manually entered the URL into your browser, check that it is correct. If you used a download link, make sure something didn't interfere with the URL in your browser; use the link again.

Version Notes Release date Documentation App SDK download
1.17.0
Major changes to the SimSpace Weaver app SDK distributable package

  • We replaced the Windows batch and Linux Bash scripts with Python-based scripts. Python 3.9 is therefore now required to use the scripts and samples, even if you don't use (or intend to use) the Python SDK.

  • This release increases support for Amazon Linux 2.

  • We fixed several bugs in SimSpace Weaver Local.

For more information, see the release notes.

Bug fix

  • We fixed a bug causing entities to become unowned if they didn't complete their transfer between remote workers.

1.14.0
New features:

  • Custom containers: Create your own Amazon Linux 2 (AL2) based container image, store it in Amazon Elastic Container Registry (Amazon ECR), and use it to run your SimSpace Weaver apps in the AWS Cloud.

  • Multiple spatial domains: Create more than 1 spatial domain in a simulation. Separate simulation logic instead of combining it all into a single spatial app. Allocate different resources to spatial domains based on their requirements.

  • Unlimited tick rate: Enable your simulation to run as fast as your code can execute. Set your simulation's clock so that it sends the next tick as soon as all apps finish their commit operations for the current tick.

SimSpace Weaver app SDK:

  • The value of tick_rate is now a string. The value must include double quotes ("). The tick rate for earlier versions is still an integer.
