This post announces and details the initial release of the Temporal Swift SDK. It highlights the SDK's Swift-first design, leveraging native concurrency features like async/await and TaskGroup. Key components like `@Workflow`, `@ActivityContainer`, `@WorkflowSignal`, `@WorkflowQuery`, `@WorkflowUpdate` macros, `TemporalWorker`, and `TemporalClient` are introduced. The post provides code examples for defining Workflows and Activities, configuring Workers, and starting Workflows. It also outlines support for advanced Temporal features and production-ready capabilities, along with links to examples and the SDK's GitHub repository.

This post announces the General Availability of the Temporal Ruby SDK. It details the high-level architecture, including the use of Rust Core and Ruby C extensions via Magnus and rb-sys. It explains the implementation of durable fibers using a custom Fiber::Scheduler and the bridging of Rust's async/Tokio with Ruby's concurrency model. The post also provides code examples for implementing Activities and Workflows, and running a Worker and executing a Workflow.

This post details the use of the Temporal TypeScript SDK to build an e-commerce order fulfillment workflow. It demonstrates defining workflows with proxied activities, implementing smart error handling with retries and non-retryable errors, integrating signals for human approvals with timeouts, and leveraging the Temporal UI for monitoring and debugging. It also provides code examples for these concepts and links to the GitHub repository for the demo.

This post announces the stable 1.0.0 release of the Temporal TypeScript SDK. It details the technical advancements including the use of V8 isolates for a deterministic workflow runtime, the adoption of a shared Rust Core SDK for enhanced reliability and faster development of other SDKs (like Python), and the evolution of the SDK's API from interface-based workflows to simple functions with proxied activities. It also highlights community contributions and future plans for safer APIs and developer tools.

This post announces the public beta of the Temporal TypeScript SDK. It details the core concepts of Workflows, Activities, Workers, and Clients within the SDK, providing code examples for each. It highlights the TypeScript-first developer experience, the use of V8 isolates for deterministic workflow execution, and the integration with a shared Rust Core SDK. The post also introduces the `@temporalio/create` tool for project setup and mentions prebuilt Gitpod environments for cloud development.

This post details the technical implementation of deterministic Workflow execution in the Temporal TypeScript SDK using V8 isolates via the `isolated-vm` npm package. It explains the necessity of determinism for Temporal's event history replay model and how isolates prevent non-determinism by providing isolated memory and stubbing out or replacing non-deterministic built-ins like `Date.now()`. It also outlines the restrictions imposed on Workflow code, such as preventing direct use of file system or HTTP modules, and directs developers to use Activities for such side effects. The post provides code examples illustrating both deterministic and non-deterministic code, and the mechanism for overriding global objects within the isolate.
