Warnings

gotcha The nightly build may contain unstable or untested changes. Not for production use. ↓

fix Use snowflake-connector-python (stable) for production.

breaking The package name is 'snowflake-connector-python-nightly' but the import path is 'snowflake.connector', same as stable. This can lead to conflicts if both are installed. ↓

fix Use a virtual environment and install only one version of the connector.

deprecated Key pair authentication using a private key file may require updated cryptography library version with nightly builds. ↓

fix Use 'pip install cryptography>=3.4' if you encounter 'cryptography.hazmat' errors.
