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().

CRE Go SDK v1.8.0 — Ordered Map Iteration Helpers and Report Verification
Go SDK version 1.8.0 is now available. This release adds cre.OrderedEntries and cre.OrderedEntriesFunc — new helper functions that return a sorted iterator over map entries, removing the boilerplate of manually collecting and sorting keys before iteration. cre.OrderedEntries works with any map whose keys implement cmp.Ordered (strings, integers, etc.), and cre.OrderedEntriesFunc accepts a custom comparator for maps with struct or other non-ordered keys. Use these helpers anywhere you iterate over a map in DON mode to guarantee consistent key ordering across all nodes. This release also adds report verification support to the SDK.
CRE CLI v1.11.0 — Registry List, Paused Workflow Warning, and Simulator Fix
CRE CLI version 1.11.0 is now available. This release adds cre registry list, a new command that displays the workflow registries configured for your organization. It also adds a warning when deploying over a paused workflow, fixes HTTP trigger --http-payload file paths to resolve relative to your working directory, and adds a duplicate-deploy check to prevent redundant on-chain transactions.
Update your CLI by running cre update when prompted, or follow the CLI Installation guide for fresh installations.
