Mender 3.4 on-prem release: integrate Mender with AWS IoT Core and other backend services

3rd Oct 2022

Today Mender 3.4 is released, including all the features we published on Hosted Mender in the last few months as part of our continuous development and rolling releases.

Thanks to the native support of AWS IoT Core and the support of Webhooks, we simplified the integration of Mender with other backend services avoiding the need to periodically poll the management API end-points to pull data and synchronize it with your cloud and on-prem infrastructure.

This release also includes, among other improvements, the following security-related features:

  • SAML Federated Authentication
  • Personal Access Tokens

Additionally, Mender 3.4 officially supports the latest Yocto LTS release, Kirkstone. Branches in meta-mender are maintained according to the same schedule, which means that the meta-mender Kirkstone branch is an LTS release, supported until at least April 2024. At the same time, support for the Zeus and Warrior branches is dropped. We still accept pull requests for them, but they become community maintained and are no longer supported by Mender.

AWS IoT Core Integration

Mender 3.4 now supports native integrations with AWS IoT Core. Most notably, it can provision devices to your AWS IoT Core instance, so your device applications are ready to send and receive data to and from the AWS services. This avoids the hassle of certificate and key pair generation and management for your AWS IoT applications.

This integration is available in all Mender plans, as well as Mender Open Source.



Mender 3.4 also supports Webhooks to send data to third-party systems. With this mechanism, it's possible to notify external applications about device lifecycle events. This helps you avoid polling and manual synchronization between Mender and other systems.

This integration is available in all Mender plans, as well as Mender Open Source.


SAML Federated Authentication

It is now possible to configure Mender to leverage a SAML-compatible Identity Provider (IdP) to identify and authenticate users. Thanks to this feature, users can log in to Mender using their existing credentials (e.g., Azure/Microsoft, AWS, or any other SAML-compatible service.

Setting up Mender as a SAML Service Provider (SP) requires uploading the SAML metadata from your IdP in the “Organization and billing” settings view. Once the XML metadata file upload is complete, you will obtain the Start URL (login URL), which will initiate the SAML authentication for your user.

Only authorized users from your IdP can log in to Mender. You can authorize users by creating them in the “User management” settings view, leaving the optional password field blank. This way, the user will be automatically linked to the SAML IdP on the first log-in.


The feature is available in the Enterprise plan on Hosted Mender and in the on-prem version of Mender Enterprise.

Personal Access Tokens

Mender 3.4 supports the generation and use of Personal Access Tokens when performing management API calls.

Personal Access Tokens are long-lived JWT tokens that you can use to programmatically access the Mender management APIs without logging in each time you need to perform API calls or handling the JWT token expiration.

Personal Access Tokens act as API keys you can use from your CI/CD pipelines or scheduled jobs to access the Mender management APIs. The Personal Access Tokens impersonate the user who generated them, including all the permissions and roles associated with the user.
