Pinia v4.0.0

Pinia 4

Pinia 4 contains only technically breaking changes: ESM only and upgrading @vue/devtools-api which now must be installed alongside pinia. It contains a major refactor of errors and dev warnings with Nostics. They will ensure detected problems are easier to fix, both by humans and by agents.
