# Changelog What's new in Polimorf — new capabilities, improvements, and fixes, newest first. Source: https://docs.polimorf.app/docs/changelog What's shipped in Polimorf, newest first. Polimorf is in early access, so expect frequent updates. Breaking changes to the public SDK or API are called out explicitly. ## August 2026 **Tool calling, generally available.** Assistants can now call your functions. Define a tool once, and Polimorf runs the full call loop — streamed or buffered — passing arguments to your handler and feeding results back to the model. See [the API reference](/docs/api/execute). **Bulk import & JSON authoring.** Import many assistants at once and author or edit configuration as JSON, with validation before publish. ## July 2026 **Evaluations.** Score a version against a dataset before it reaches users — compare versions side by side and gate risky changes on the results. **Dashboard redesign.** A refreshed workspace with a global workspace switcher and a cleaner, faster surface for building and shipping assistants. ## June 2026 **Polimorf.** Rebranded from the original codename to **Polimorf**. The SDK is now published as [`@polimorfapp/sdk`](https://www.npmjs.com/package/@polimorfapp/sdk) and the API lives at `api.polimorf.app`. **Google sign-in.** Log in and sign up with Google, alongside email. ## Earlier **Knowledge & RAG.** Point an assistant at your docs, policies, and macros. Polimorf searches them on demand and cites every source in the answer. **Versions & environments.** Every edit is a version; promote or roll back to any environment in one click while your app keeps calling a single stable slug. **Traces, tokens & cost.** Every run is captured — prompt, tokens, latency, and cost — with opt-in content capture. **Typed SDK & streaming.** `@polimorfapp/sdk` handles auth, timeouts, cancellation, and a typed error catalog, with token-by-token streaming over Server-Sent Events. See [Streaming](/docs/streaming).
