Dear community,
Apache CouchDB %VERSION% 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.
CouchDB 2.3.0 is a feature release, and was originally published on 2018-12-06.
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!
See the official release notes document for an exhaustive list of all changes:
http://docs.couchdb.org/en/stable/whatsnew/2.3.html
Release Notes highlights:
- (Multiple) Clustered purge is now available. This feature restores the
CouchDB 1.x ability to completely remove any record of a document from a
database. Conditions apply; to use the feature safely, and for full details,
read the complete Clustered Purge documentation.
- A new config setting is available, allowing an administrator to configure
an initial list of nodes that should be contacted when a node boots up. Nodes
in the seedlist that are successfully reached will be added to that node’s
_nodes database automatically, triggering a distributed Erlang connection and
replication of the internal system databases to the new node. This can be used
instead of manual config or the cluster setup wizard to bootstrap a cluster.
The progress of the initial seeding of new nodes is exposed at the GET /_up
endpoint.
- Replication supports ipv6-only peers.
- The UUID of the server/cluster is once again exposed in the GET / response.
This was a regression from CouchDB 1.x.
- Stats counts between job runs of the replicator are no longer reset on job
restart.
- CouchDB’s _bulk_get implementation now supports the multipart/mixed and
multipart/related content types if requested, extending compatibility with
third-party replication clients.
- CouchDB no longer forces the TCP receive buffer to a fixed size of 256KB,
allowing the operating system to dynamically adjust the buffer size. This can
lead to significantly improved network performance when transferring large
attachments.
- To improve security, there have been major changes in the configuration of
query servers, SSL support, and HTTP global handlers. See the release notes for
important upgrade information.
- All python scripts shipped with CouchDB, including couchup and the dev/run
development cluster script, now specify and require Python 3.x.
- CouchDB is now compatible with Erlang 21.x.
- The embedded version of rebar used to build CouchDB has been updated to the
last version of rebar2 available. This assists in building on non-x86 platforms.
- Plus many other performance improvements, bugfixes, and UI improvements!
On behalf of the CouchDB PMC,
