More client-server, better notifications, and more

Bringing you a few enhancements and bug fixes. Let's check them out!

Client-server

The experiment client-server architecture got even more fixes.

Want to test? Set CRUSH_CLIENT_SERVER=1.

Better notifications

We updated our notifications to be smarter. They will now work when using Crush over SSH, and support for more platforms were improved as well.

Copilot fixes

A couple more models that require the Responses API will now use them and work again. This includes GPT 5.4 and GPT 5.5.

Bedrock fixes

A couple more improvements were made to AWS Bedrock, in particular regarding Bedrock Europe and the support for authentication via aws login.

See you in the next release! Charm
