What shipped, newest first. The full commit history lives on GitHub.
Each key now holds a separate value per environment, with development, staging, and production by default and any others you add. Switch environment in the dashboard and generate the matching .env. All of it stays in the local vault.
A full rebuild. The vault is encrypted in your browser with AES-256-GCM under a passphrase you choose, and stored on your device. No account, no server, no database, no subscription. Generate a .env on demand, keep a tamper-evident local audit log, and export an encrypted backup whenever you like.
