Subject [ANNOUNCE] Apache CouchDB 2.3.0 released
Date Thu, 06 Dec 2018 17:09:54 GMT
Dear community,

Apache CouchDB 2.3.0 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,
Joan Touzet
