DuckDB is an open-source, in-process analytical database designed for fast SQL analytics on local data. This page is the official announcement of DuckDB 2.0.0 LTS, codenamed “Cinnamon Teal,” published on the project’s blog and positioned as the biggest feature release to date.
The release ships a polished version of the Quack remote protocol, asynchronous I/O, a first-class VARIANT type, agent mode, triggers, and an extensible SQL parser, built from close to 20,000 commits since DuckDB 1.5. The post summarizes the highlights and then walks through breaking changes and migration guidance.
It is written for data engineers, analysts, and developers who already use DuckDB or are evaluating an upgrade to the LTS line. Readers who need installation steps or API details can follow the linked documentation sections.
Use this page to understand what changed in 2.0.0, assess compatibility impact before upgrading, and locate the migration notes. It is a release reference rather than a tutorial, so pair it with the official documentation for hands-on work.
In short, it is the authoritative starting point for anyone adopting DuckDB 2.0.0 LTS in production.
