Agentic applications and orchestration

Agents Kit 2.2

Human-In-The-Loop for the Agent Editor

The Agent Editor now supports configuring end user visibility and permissions for agent tools and knowledge bases. Users can choose to show, hide or request an approval for a tool invocation and optionally overwrite the tool name and description displayed to the end user.

Response streaming

When streaming is enabled for an agent and the chat interface of the Conversational UI module is used, the model’s response will appear word by word in real time, rather than waiting for the full response to be generated before displaying it. Upgrade to Agent Editor 2.2.1+, AgentCommons 2.2.0+, and Conversational UI 7.2.0+ to try it out. You can enable streaming for existing agents for the frontend in the model settings of your model resource in Studio Pro or your agent in runtime.

Streaming responses is supported across the following connectors:

• Mistral Connector 2.1.0+
• Google Gemini Connector 2.1.0+
• OpenAI Connector 9.2.0+ (including Azure Foundry models)
• Mendix Cloud GenAI Connector 7.2.0+

In the near future, streaming responses will be supported for the Amazon Bedrock connector, too.

Claude Sonnet 5 and Opus 5 on GenAI Resource Packs

Anthropic Claude Sonnet 5 and Claude Opus 5 are now available on Mendix Cloud GenAI Resource Packs, accessible directly through the GenAI Text Generation resource for your applications.

With this, you gain access to the newest Claude generation without reworking anything. Both models join the Sonnet and Opus families already on the resource at the same GenAI Unit exchange rates as the rest of their family.  The full list is available in Supported Models.

Maia Units: User level insights and budgeting

Maia Units gives a clear, real-time picture of an organization’s Maia usage as well as the controls to manage it. From Control Center, opening the Maia page allows one to see total units, how many have been consumed, and how capacity is allocated across users. A Company Admin can see per user exactly who’s using what and review the limits configured for each user so usage stays within bounds.
When your team is ready to do more with Maia, you can purchase additional units by provisioning more resources using your cloud tokens, enabling you to scale your Maia usage with your organization.

History pane additions

The History pane in Mendix 11 now offers an enhanced experience with the ability to inspect the history of other branches. Previously, you could only see changes pushed to the server by your colleagues. Now, you can quickly view the history of any branch without needing to download the entire branch, streamlining your workflow and making collaboration even smoother.

Additionally, we’ve introduced a convenient feature that allows you to create a new branch directly from a specific commit. Simply use the filters to locate the desired commit, right-click on it, and select the option to create a new branch. This makes it incredibly easy to isolate and work on specific versions of your project.

Search history at your fingertips

Search is essential for navigating Mendix applications and understanding relationships between microflows, pages, and entities. When investigating topics such as what is used where, developers often need to keep previous searches available while exploring new ones. Previously, this was possible with two Find Results panels, but the experience was hard to find and could be cumbersome to manage.

To make this workflow easier, we redesigned the Find Results panel and introduced a new History Bar. It automatically keeps track of your searches and lets you switch between current and previous results with a single click. You can revisit searches where you left off and remove entries you no longer need.

The new experience is enabled by default, making it easier than ever to explore, compare, and navigate search results.

Java 25 support is here

Java 25 is now supported in Mendix 11.14, with support also coming to Mendix 11.12 in a future patch. Java powers the Mendix Runtime, so keeping your applications on the latest stable Java release helps ensure they continue to benefit from ongoing platform improvements, performance optimizations, and long-term support.

Upgrading to Java 25 helps you get more from your applications with minimal effort. In our internal testing, Java 25 consistently outperformed Java 21, delivering measurable performance improvements across a wide range of benchmarks. At the same time, moving from Java 21 to Java 25 is expected to be straightforward for most applications. Java remains highly backward compatible, and our testing showed the transition to be largely seamless, making Java 25 an easy way to gain performance and stay on a modern supported platform.

To enable Java 25, update the Java version in your project settings. New projects will use Java 25 by default, while existing projects will continue using their current Java version until you choose to change it. Java 21 remains available in Mendix 11, but it is now deprecated and Studio Pro provides a built-in quick fix to help you upgrade. Looking ahead, Java 21 support will be removed in Mendix 12, so we recommend moving to Java 25 to stay on a supported, future-ready runtime.

Clear specific objects from the offline database

Offline-first applications enable powerful mobile experiences, but they also require control over what data is stored on the device. While the Clear from Device action already allowed developers to remove all objects of a specific entity, many use cases required more granular control. Developers needed a way to clean up only selected data and keep the offline database aligned with their application’s needs.

With this release, the Clear from Device action can now also accept individual objects and lists of objects. This allows you to remove specific records from the offline database instead of clearing an entire entity. As before, this action only removes data from local device storage and does not delete the objects from the server or trigger any delete behavior. Use it to selectively manage offline data, reduce storage usage, and keep only the information that is relevant for your users.

Enterprise-grade platform

Certificate management APIs

We introduced landscape wide Certificate Management earlier this year where Mendix Admins can centrally manage SSL/TLS certificates for incoming connections using Certificate Management in Control Center for Mendix Cloud. With 11.14, we are excited to announce APIs to list, create, update, replace and delete central certificates.

APIs will help integrate certificate management with your existing enterprise tooling and automate the end-to-end certificate management lifecycle to avoid any operational impact to the app when someone forgets to apply the renewed certificate in time.

Check out the API docs and get cracking to streamline your certificate management process!

New database metrics for Mendix Cloud

Metrics are crucial for understanding the performance of your Mendix application. On popular demand, we have added three advanced database specific metrics:

• Average Database Bloat Ratio – Tracks dead rows across user tables to spot when autovacuum lags.
• Maximum Table Bloat Ratio – Highlights the bloat percentage of the single most bloated table (system vs. application).
• Largest Table Size – Shows the size of the biggest table to help identify archiving or partitioning needs.

These metrics will help deduce remediations to performance issues such as resizing the container to get more database space or debloating the database via a request to Support.

Check out the documentation and review these alerts in your Mendix Cloud apps under the Metrics page.

Variable selector expansion in Mendix Pipelines

Building integrations in your Mendix Pipelines with deployment APIs and external systems often requires pipeline steps to work with dynamic information from your Mendix environment. With this release, Mendix-provided variables are now available directly through the variable selector, making them easier to discover and use when configuring POST and GET request steps. This simplifies the setup of integrations with deployment APIs and external systems, where values such as application, environment, or execution-specific identifiers often need to be passed dynamically instead of being hardcoded. This enhancement lays the foundation for broader variable support in Pipelines, and on top of that, additional Mendix-provided variables are planned to come your way in future releases.

Data and integration

Iceberg bridge for Mendix Event Broker

In 11.12, we introduced the Change Data Capture (CDC) feature that lets you stream data change events from your Mendix applications to Mendix Event Broker (or your own Kafka-compatible broker). Now, we’re rolling out Iceberg bridge for Mendix Event Broker. This bridge will take care of the transformation of the CDC events into Iceberg tables as well as its propagation into your data lake. Setting this up only requires a few simple steps: Log in to your Mendix event broker platform, add an Iceberg bridge, choose the data lake type, and select the CDC events you’d like to connect. Then watch as your Mendix app data gets replicated in your data lake.

The Iceberg bridge is available for all apps from Mendix 11.12 onwards, meaning that all customers that use CDC with Mendix Event Broker will be able to leverage this.

Siemens Xcelerator

New FDS Gateway Login Connector

The new FDS Gateway Login Connector enables Siemens product groups to integrate Mendix applications with Siemens Foundational Services (FDS) for authentication and Single Sign-On (SSO). Users can sign in with Siemens ID or a federated workforce identity provider, while organizations continue to leverage their existing IAM infrastructure.
The connector simplifies adoption of Siemens authentication services and standards across Siemens Xcelerator solutions.
