Full Release Notes

# Cybermode 2026

This is a small release with a big punch: Crush (and really, [Bubble Tea v2](https://github.com/charmbracelet/bubbletea/releases/tag/v2.0.0-rc.2)) now supports Mode 2026, which synchronizes the renderer with the rendering cycles in the terminal, resulting in even smoother rendering overall.

Other small niceties in this release:

* Assisted-by is now the default
* Small rendering edge cases have been fixed
* @novalis78 fixed a bug with tool discovery

Enjoy the release! We have lots more in the pipe. 💘

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.18.2/checksums.txt), for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.18.2/checksums.txt'
```

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' \
  --cert 'https://github.com/charmbracelet/crush/releases/download/v0.18.2/checksums.txt.pem' \
  --signature 'https://github.com/charmbracelet/crush/releases/download/v0.18.2/checksums.txt.sig' \
  ./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!
