v1.4.0

Spin v1.4.0

We are excited to announce the release of Spin 1.4! 🎉

This release includes several exciting new features:

• A built-in SQLite database provides relational storage right out of the box: nothing to install, no connection strings
• A new command spin doctor which facilitates diagnosing and detecting problems when building and running your apps
• A Plugin badger which checks for updates of installed plugins and prompts you to upgrade so you know when a new version is available

As always, thanks to all of our contributors for continually improving Spin! ❤️

Verifying the Release Signature

First, install cosign. This is the tool we'll use to perform signature verification. Then run the following command:

cosign verify-blob \
    --signature spin.sig --certificate crt.pem \
    --certificate-identity https://github.com/fermyon/spin/.github/workflows/release.yml@refs/tags/v1.4.0 \
    --certificate-oidc-issuer https://token.actions.githubusercontent.com \
    --certificate-github-workflow-sha 7aab1fe43be70a271ba6336b959cd52191fc2253 \
    --certificate-github-workflow-repository fermyon/spin \
    spin

If the verification passed, you should see:
