Dear community,

Apache CouchDB® 3.1.1 has been released and is available for download.

Apache CouchDB® lets you access your data where you need it. The Couch Replication Protocol is implemented in a variety of projects and products that span every imaginable computing environment from globally distributed server-clusters, over mobile phones to web browsers.

Store your data safely, on your own servers, or with any leading cloud provider. Your web- and native applications love CouchDB, because it speaks JSON natively and supports binary data for all your data storage needs.

The Couch Replication Protocol lets your data flow seamlessly between server clusters to mobile phones and web browsers, enabling a compelling offline-first user-experience while maintaining high performance and strong reliability. CouchDB comes with a developer-friendly query language, and optionally MapReduce for simple, efficient, and comprehensive data retrieval.


Pre-built packages for Windows, macOS, Debian/Ubuntu and RHEL/CentOS are available, along with the apache/couchdb and couchdb Docker containers.

CouchDB 3.1.1 is a maintenance release, and was originally published on 2020-09-18.

The community would like to thank all contributors for their part in making this release, from the smallest bug report or patch to major contributions in code, design, or marketing, we couldn’t have done it without you!
