Pulumi emphasizes the importance of stable CLI and SDK releases due to the critical role they play in infrastructure deployment, which could lead to outages if any bugs occur. To enhance stability, Pulumi has introduced dev releases for their CLI and SDKs, allowing users to access the latest features and bug fixes before they are widely deployed. These dev releases are automatically generated whenever a pull request is merged, providing a standardized way to install the latest versions across platforms like Linux, macOS, and Windows, and for languages including Node.js, Python, .NET, and Go. Pulumi uses these dev releases internally for testing their cloud deployments and other applications, ensuring that potential issues are identified early. By offering these releases, Pulumi aims to make it easier for users to test new code and ensure compatibility with their production environments, while also encouraging feedback on any bugs encountered. Instructions for installing these dev releases are available in the Pulumi documentation.
