Key points
- DuckDB 2.0.0 LTS "Cinnamon Teal" is now available.

- Adds asynchronous I/O, VARIANT type, and agent mode.
- LTS support for version 2.0.0 extends until October 2027.
Major Feature Release
DuckDB has announced the release of version 2.0.0 LTS, codenamed "Cinnamon Teal." This update is described as the largest feature release to date for the in-process analytical database. It incorporates nearly 20,000 commits since the previous 1.5 version, focusing on new capabilities rather than just stability.
Key New Features
Version 2.0.0 introduces several new functionalities. A polished version of the Quack protocol is included, enhancing client-server capabilities that were first previewed in DuckDB 1.5.3. This protocol allows any DuckDB process to serve its databases and now features a new CONNECT statement for improved ergonomics. Other significant additions include asynchronous I/O, a first-class VARIANT type, agent mode, triggers, and an extensible SQL parser.
Long-Term Support
DuckDB 2.0.0 is designated as a Long-Term Support (LTS) release, with support guaranteed until at least October 2027. To facilitate migration, the support period for DuckDB 1.5 has been extended until March 2027, effectively making it an LTS release as well. The previous LTS version, 1.4, remains supported until late November 2026.
Installation and Documentation
Users can install the new version via the official installation page. Client libraries for CLI and Python are immediately available, while other client libraries (Go, R, Java) and some extensions may take a few days to be released. Comprehensive documentation for the new features is available on a dedicated "What's New in the Docs for 2.0" page.
