Delta Lake LTS

The delta-rs project regularly publishes releases for Python and Rust users. Many enterprise users simply cannot follow the rapid release cadence and fall behind on security fixes, performance improvements, or even bug fixes as upstream APIs change. Buoyant Data's Delta Lake Long-Term Support (LTS) provides customers with access to regularly built, tested, and updated Python packages. For Rust customers, access to the LTS Git repository is provided.

Customers of Delta Lake LTS receive:

• Organization access to a private Python package server
• Access to a private Git repository with all the changes made in the respective LTS branches.
• Access to an RSS feed with changelog entries detailing backported patches and fixes.
