Full Release Notes

# Community patch

We're shipping a small release with two nice contributions from the community.

## Better background jobs

@portertech implemented a new `wait: true` optional parameter on the `job_output` tool. This means that the model can now ask Crush to wait for a background job command to finish before returning its output. This is important to prevent polling, which would also consume more tokens than needed.

## LSP connection fix

@taigrr worked on a patch to ensure that LSP connections are closed once the server is shut down.

Enjoy!

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.47.0/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.47.0/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.47.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.47.0/checksums.txt.sigstore.json'
```

Then, verify it using [`cosign`](https://github.com/sigstore/cosign):

```bash
cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle 'checksums.txt.sigstore.json' \
  ./checksums.txt
```

If the output is `Verified OK`, you can safely use it to verify the checksums of other artifacts you downloaded from the release using `sha256sum`:

```bash
sha256sum --ignore-missing -c checksums.txt
```

Done! You artifacts are now verified!
