Highlights

These are the v1.16 release highlights:

Multi-application workflows

The Workflow API now supports multi-application workflows, enabling you to orchestrate complex business processes that span across multiple applications. This allows a workflow to call activities or start child workflows in different applications, distributing the workflow execution while maintaining the security, reliability, and durability guarantees of Dapr’s workflow engine.

By using multi-app workflows, you can design distributed business processes, such as cross-application order processing, complex approval chains that involve multiple workflows and activites, and AI/ML pipelines that coordinate between LLM services and GPU-intensive workloads. Workflow durability and consistency is maintained across application boundaries, ensuring your distributed workflows remain resilient even when individual applications experience temporary failures.

Mutli-application workflows are supported in Java and Go SDKs as of this release. Learn more with the multi-app workflows documentation.

Workflow performance

Dapr continues to invest into the Workflows API building block; with this release focusing on performance and stabilization, particularly when using Workflows for production at scale. These enhancements make Dapr Workflows more robust and performant for high-throughput workloads with high-concurrency requirements.

Key Improvements:

• Memory Optimization: Reduced memory allocations by pooling reused memory to reduce memory allocations and be smarter about object lifetimes to minimize garbage collection overhead.
• Concurrency Enhancements: Removed shared memory contention in both daprd and Scheduler to allow for higher throughput of workflow operations.
• Scheduler Reliability: Fixed deadlocks in the Scheduler service that could occur under extreme load conditions, ensuring more reliable job scheduling and execution.
• Connection Management: Improved and increased the number of cross-daprd and daprd-to-Scheduler streams to allow for more concurrent operations and reduce bottlenecks.

The results of these improvements mean that Dapr handles larger Workflow throughputs, consumes less memory & CPU overall, and the consumption of these resources is more stable.

The following table shows results of testing the performance of Workflows from Dapr v1.15 and v1.16.

• Run on a 3 node EKS cluster, using t2.medium node sizes.
• Actor state store is an Amazon RDS instance using db.r6g.2xlarge.
• Go Workflow application which starts all scheduled Workflows in parallel, with each workflow executing 15 no-op activities sequentially.

Below are the memory and CPU usage when running 1000 workflows with 3 application replicas. The v1.16 engine uses less CPU & memory and its usage is more stable.

HTTP Streaming / SSE support for HTTP Endpoints

You can now use Dapr to proxy requests to external HTTP servers that work with streaming or Server-Sent Events (SSE), allowing Dapr to provide important functionality when communicating with MCP servers and AI agents like middleware authenticaton, resiliency policies, telemetry and distributed tracing.

Learn more on HTTP streaming with service invocation.

Conversation API Tooling Support (alphaV2)

Dapr now supports tool calling in the Conversation API, enabling Large Language Models (LLMs) to interact with external functions and APIs during conversations. This feature allows applications to provide tools that LLMs can interact with to retrieve real-time data, perform calculations, or execute actions as part of the conversation flow. This makes conversations more interactive and dynamic, allowing LLMs to integrate with external services and data sources.

The new AlphaV2 Conversation API introduces:

• Function tools: Define tools with JSON Schema parameters that LLMs can invoke
• Tool choice control: Configure tool usage with options such as auto, none, required, or a specific tool
• Tool call messages: Conversation history now supports assistant tool calls and tool responses
• OpenAI Alignment: API design follows OpenAI’s tool calling patterns for a familiar developer experience The API was updated to Alpha2 Applications using the previous AlphaV1 API can migrate to AlphaV2 to access tool calling and benefit from the improved, OpenAI-aligned interface.

Try tool calling with Conversation API quickstarts

Sentry Service JWT and OIDC Support

The Sentry service was extended to include advanced authentication capabilities with JWT and OIDC support, enabling integration with external identity providers through workload identity federation.

You can configure Sentry to issue JWT tokens and expose OIDC discovery endpoints (/.well-known/openid-configuration and /jwks.json). These tokens can, for example, be exchanged with Microsoft Entra ID for Azure access tokens by creating a Federated Identity Credential tied to your Dapr app’s SPIFFE ID.

• Federated Identity Credential integration: Authenticate with Microsoft Entra ID using SPIFFE IDs, no need for long-lived secrets.
• JWT and OIDC in Sentry: Enable JWT issuance and OIDC discovery endpoints in Sentry.
• Consistent identity across environments: Same authentication model regardless of where your Dapr app is running.

See the Managed identities and workload identity federation and Authenticating with a Federated Identity Credential in Azure for a walkthrough.

W3C Baggage Support for Distributed Tracing

Dapr now supports W3C Baggage propagation alongside trace context, enabling you to pass custom key-value pairs across your distributed services. This allows you to attach contextual information like user IDs, server nodes, or business-specific tags that travel with your traces throughout the entire request flow.

This feature supports 2 propagation methods:

• OpenTelemetry context baggage
• Header/Metadata baggage

Dapr automatically handles the propagation and encoding requirements, ensuring your baggage data reaches downstream services while maintaining security boundaries between different propagation domains. This makes it easier to correlate business context with technical traces, improving debugging, and observability across your microservices architecture.

Learn more on how to configure and use baggage.

Components

SDK Improvements

.NET SDK

The v1.16 release of the Dapr .NET SDK delivers a set of targeted enhancements focused on developer productivity and runtime efficiency. Most notably, this version debuts Roslyn analyzers and accompanying code fixes that enforce best practices around SDK configuration and usage. This marks the beginning of a more guided and prescriptive development experience, reducing setup complexity and surfacing misconfigurations early.

Framework support has been consolidated with the depreciation of .NET 6 and 7, aligning the SDK with .NET 8 and 9. This shift enabled internal refactoring that improves performance and resource utilization across core components.

On the feature front, the SDK now supports the latest capabilities in the Dapr conversation API with tooling, as well as the overwrite flag for job scheduling. A critical bug affecting encryption and decryption of large files exceeding 4 GB has been resolved.

Dapr Workflows orchestrated using the .NET SDK are now considered stable, supporting both short-lived and long-running processes. Performance has been further improved through targeted optimizations, including new helper methods that enable deterministic parallelization with bounded concurrency.

• Dotnet SDK Workflow ASP.NET examples

Learn more at the Dapr Community call for .NET SDK on Sept 3rd 2025

Python SDK

The Python SDK release brings several key improvements and new features to enhance the developer experience. Most notably, the release introduces Conversation API (alphaV2) tool calling and Jobs API support, along with enhanced transactional state operations that now support metadata for more flexible state management.

The release also addresses several important bug fixes, including resolving JSON serialization errors that occurred during internal Dapr errors in actor method calls, fixing issues with receiving actor reminders that had empty state, and improving type hint support for better PEP 561 compliance and IDE integration.

This release includes improvements to error handling, particularly for the HTTP client, allowing users to implement more appropriate error handling behavior.

The FastAPI extension documentation has been updated to resolve warnings about non-annotated attributes. These changes collectively make the Python SDK more robust, user-friendly, and aligned with modern Python development practices.

• Python SDK Workflow examples

Java SDK

The Java SDK updates focused on workflow capabilities and developer experience improvements. Multi-app workflow support enables orchestrating business processes across multiple applications, while the new compensation workflows pattern provides robust error handling and rollback mechanisms for complex transactions.

Additional improvements include failure policy support for the Jobs API, tool calling support for the Conversation API, custom activity name registration for workflows, and SpringBoot workflow examples.

The Java SDK enhanced SpringBoot integration with improved connection configuration, health check parameters, and stable module releases for Workflows, SpringBoot, and testcontainers-dapr modules. Developer experience was further improved with better component specification parsing, and comprehensive documentation across SpringBoot properties, and Dapr Jobs and Conversation APIs.

The Java SDK has newly expanded examples for the following:

• SpringBoot Workflows
• Java SDK Workflows
• Java SDK Workflows with the compensation pattern
• Java SDK Jobs API
• Java SDK Conversation API

Javascript SDK

This release of the Javascript SDK brings several improvements and fixes to enhance the developer experience and maintainability of the Dapr Javascript SDK.

Fixed spelling mistakes on the subscriptionManager for the PubSub API.

The workflow component has been cleaned up and now only uses dapr workflow component aligning with Dapr ecosystem.

Multiple infrastructure improvements have been introduced including removing the prettifier from the build pipeline for better efficiency and updating the Dapr versions used in end-to-end tests to maintain compatibility with the latest Dapr features.

Updated the package metadata to reflect current author and license information, and disabled the issue-closing bot to improve repository management processes. These changes collectively improve the reliability and maintainability of the Javascript SDK while ensuring it stays current with the broader Dapr ecosystem.

Go SDK

The Go SDK implements support for the runtime changes introduced in this release including the new Conversation Alpha2 API functionality.

The existing workflow methods exposed by the Go SDK’s Dapr client have been removed as of this release and are no longer available. Guidance has been updated regarding the workflow (wrapper) exposed by the Go SDK, the new recommended path is to use the dapr/durabletask-go library directly rather than the wrapper provided.

The Go SDK also supports multi-app workflow orchestration across all your Dapr applications within a namespace.

Check out the examples for more information: github.com/dapr/go-sdk/examples.

Rust SDK (alpha)

The Rust SDK has been updated in line with the runtime changes, with the new Conversation Alpha2 support coming soon.

The MSRV remains at 1.78 for this release.

Upgrading to Dapr 1.16

To upgrade to this release of Dapr, follow the steps here to ensure a smooth upgrade. You know, the one where you don’t get red errors on the terminal.. we all hate that, right?

Local Machine / Self-hosted

Uninstall Dapr using the CLI you currently have installed. Note that this will remove the default $HOME/.dapr directory, binaries and all containers dapr_redis, dapr_placement and dapr_zipkin. Linux users need to run sudo if docker command needs sudo:

dapr uninstall --all

For RC releases like this, download the latest and greatest release from here and put the dapr binary in your PATH.

Once you have installed the CLI, run:

dapr init --runtime-version=1.16

Wait for the update to finish, ensure you are using the latest version of Dapr(1.16) with:

$ dapr --version

CLI version: 1.16
Runtime version: 1.16

Kubernetes

Upgrading from previous version

You can perform zero-downtime upgrades using both Helm 3 and the Dapr CLI.

Upgrade using the CLI

Download the latest RC release from here and put the dapr binary in your PATH.

To upgrade Dapr, run:

dapr upgrade --runtime-version 1.16 -k

To upgrade with high availability mode:

dapr upgrade --runtime-version 1.16 --enable-ha=true -k

Wait until the operation is finished and check your status with dapr status -k.

All done!
