Welcome to the Unofficial Release Notes for Snowflake, where I combine all release notes from multiple locations, including features, drivers, and other things in a single location. As the title says, these are unofficial release notes, and I will add some commentary with my thoughts.

September was not a surprise, and it continued the high pace of innovation and change at Snowflake Data Cloud.

This month, we cover up to release **_7.34_**. Please give me suggestions if I should continue with these monthly combined release notes. Comment below or find me on Linkedin.

### Conclusion

I hope you enjoyed the Unofficial Release Notes in this monthly series about the Snowflake. See you again in October. I asked for feedback, and please reach out and give me feedback if this series has any value.

This month continues to grow in features; many of the features are on governance, security, and application. One interesting point is that Snowflake is starting to add hybrid tables support into many of their drivers, so I assume this means it is coming out soon in Public Preview.
