CRE CLI v1.12.0 — Workflow List Command and Simulator Improvements
CRE CLI version 1.12.0 is now available. This release adds cre workflow list, a new command that lists all workflows deployed for your organization. It also adds a consistent details block after deploy, activate, pause, and delete showing the registry, contract address, transaction hash, workflow name, and workflow ID, fixes --limits none not fully disabling engine-level limit enforcement, and resolves an invalid owner-address bug.
Update your CLI by running cre update when prompted, or follow the CLI Installation guide for fresh installations.

CRE TS SDK v1.6.0 — Custom Rust Plugin Support and Non-Determinism Warnings
TypeScript SDK version 1.6.0 is now available. This release adds custom Rust plugin support — you can now inject Rust logic into your TypeScript workflows using the new --plugin flag in cre-compile, providing a pre-built .plugin.wasm compiled from your own Rust crate. The SDK ships example packages (@chainlink/cre-rust-inject-alpha, @chainlink/cre-rust-inject-beta) and a prebuilt plugin example to help you get started. This release also adds compile-time non-determinism static analysis: the SDK now emits warnings during cre workflow build and cre workflow simulate when it detects potentially non-deterministic patterns such as Date.now(), Math.random(), or Promise.race().
