Rig v0.37.0 now available!

[gold-silver-copper]

This is an absolutely MAJOR release, with a whole slew of awesome additions. Let's get started.

Rig Facade Crate

Rig now has a top level facade crate which reexports rig-core and all integration crates, gated by features. Previously, rig-core was the main crate that users would interact with, and they had to add integration crates manually. No longer is that the case! You can simply do cargo add rig and it just works! Want to enable a feature? Just run cargo add rig --features="surrealdb" (replace surrealdb with the actual features you need). This should make DX much better, and it's also just plain nice. Awesome! The new rig facade crate should work as a simple drop in replacement for rig-core, so try it out!

Repository structure

Parallel to the facade crate, the whole rig repo has had a complete makeover. Inspired by the structure of the bevy project, rig now stores ALL crates in a top level crates folder- no more separate rig-integrations folder. Tests and examples have also been moved to the top level, where they will be more visible. Many AI agent specific configurations have been removed from the project, users of affected AI agents are encouraged to build their own configs.

Memory Policies and Compaction

Rig now has experimental support for creating custom memory policies and conversation compaction. This is made possible by the new rig-memory crate, and memory feature. This sets the groundwork for creating long running agents who can manage their own memory.

Provider improvements

Openrouter now supports TTS and STT

Bedrock scheme mapping is improved

Ollama's think parameter now supports low, medium, and high modes, in addition to boolean true/false.

Copilot supports model listing

OpenAI PDF support has been improved

Gemini telemetry accuracy has been greatly improved

Breaking Changes

Chat::chat now takes &mut Vec<Message> and appends the prompt, tool calls, tool results, and assistant response back into caller-owned history. Callers should not pre-push the user prompt before calling chat. See #1733.

The OpenAI chat-completions UserContent enum has a new File variant, and OpenRouter file content now includes file_id. Exhaustive matches or struct literals may need updates. See #1732.

The root facade feature surface was cleaned up, including removal of the old 'all' feature. See #1764.

Final notes

Beyond all the changes mentioned above, as always there have been many smaller improvements and bug fixes. Huge thank you to everyone who has contributed. We build rig, rig builds us!
