Azure Spring Apps is improved on an ongoing basis. To help you stay up to date with the most recent developments, this article provides you with information about the latest releases.

This article is updated quarterly, so revisit it regularly. You can also visit Azure updates, where you can search for updates or browse by category.

Q3 2024

The following updates are now available:

• Conveniently access app logs in the Azure portal: We now offer a more convenient and efficient way to query app logs and do log streaming on the Azure portal.

Q2 2024

The following updates are now available in the Enterprise plan:

• Richer log of Application Configuration Service: The Git revision is a crucial piece of information that indicates the recency of configuration files. Currently, the Application Configuration Service logs the Git revision to enhance troubleshooting efficiency. For more information, see the Examine Git revisions of the configuration files section of Use Application Configuration Service for Tanzu.

• Managed OSS Spring Cloud Config Server (preview): The open-source version of Spring Cloud Config Server provides a native Spring experience to developers. Now we offer managed Spring Cloud Config Server to dynamically retrieve configuration properties from central repositories. For more information, see Configure a managed Spring Cloud Config Server in Azure Spring App.

• Custom actuator endpoint support: Users might want to use a different port or path for the actuator due to security concerns, but this choice can result in the Application Live View being unable to connect to the app. This feature enables Application Live View to work with apps that have a non-default port or path for the actuator. For more information, see the Configure customized Spring Boot actuator section of Use Application Live View with the Azure Spring Apps Enterprise plan.

• Disable basic auth for the test endpoint of an app: Azure Spring Apps provides basic authentication to protect the test endpoint of an application instance. When a user's app is integrated with their auth server, this basic authentication becomes unnecessary. If the user has a good understanding of the application's security, this feature lets them disable the basic authentication provided by the Azure Spring Apps service, making the tests against the application closer to a real-world environment. For more information, see the second tip in Set up a staging environment in Azure Spring Apps.

• Private storage access for virtual network injection: The private storage access feature enables routing of traffic through a private network for backend storage hosting application assets like JAR files and logs. This feature enhances security and can potentially improve performance for users. For more information, see Configure private network access for backend storage in your virtual network (Preview).

• Support Job (preview) in Azure Spring Apps: This feature enables customers to run their ephemeral applications in Azure Spring Apps natively. It offers batch job management and execution, along with integration with managed components. For more information, see Job in Azure Spring Apps (Preview).

You can also export configuration files pulled by the Application Configuration Service from upstream Git repositories to your local environment through the Azure CLI. This process helps you examine the content and use configuration files for local development. For more information, see the Examine configuration file in ConfigMap section of Use Application Configuration Service for Tanzu.

Q4 2023

The following updates are now available in the Enterprise plan:

• Spring Cloud Gateway supports a response cache: The response cache enables services and clients to efficiently store and reuse responses to HTTP requests. You can configure the memory size and the time-to-live of the cache and apply settings at the route-level or globally. For more information, see the Configure the response cache section of Configure VMware Spring Cloud Gateway.

• API Portal supports enable/disable of the try-out option: The try-out feature enables you to try out APIs through the centric view of API Portal.

The following update is now available in the Enterprise and Basic/Standard plans:

• Planned maintenance (public preview): Azure Spring Apps regularly patches server-side components that your applications depend on to make sure they are secure and up to date. These components include the JDK, Spring Cloud middleware, APM, base OS image, and runtime infrastructure. For such patches to take effect, you need to restart your applications. With planned maintenance, you can schedule a time on a specific day for such mandatory restarts. For more information, see How to configure planned maintenance (preview).

• Auto sync of certificates: Some Azure Spring Apps features secure your applications with certificates of your choice. With auto sync of certificates, you can now rotate your certificates in Azure Key Vault and they automatically sync to Azure Spring Apps.
