couchdb 2.1.1
- CouchDB now supports compilation and running under Erlang/OTP 20.x
- The couch_peruser functionality is now really fixed
- The cookie domain for AuthSession cookies, used in a proxy
authentication configuration, can now be customized via the ini file
- It is now possible to modify shard maps for system databases
- Due to an Erlang bug (ERL-343), invalid paths can be returned if
volumes are mounted containing whitespace in their name (fixed)
- The current node's local interface can now be accessed at
/_node/_local/{endpoint} as well as at
/_node/<nodename>@<hostname>/{endpoint}.- The Dockerfile in the source
repository has been retired
- Fauxton now uses a version of React with a BSD license.
- CouchDB now no longer decompresses documents just to determine their
uncompressed size
- The design document cache (ddoc_cache) has been rewritten to improve
performance
- Mango now supports partial indexes
- Mango queries can now be paginated
- Mango _find accepts an execution_stats parameter
- Mango now requires that all of the fields in a candidate index must
exist in a query's selector
- Other minor improvements.
couchdb 2.1.0
- The Mango _find endpoint supports a new combination operator,
$allMatch.
- New scheduling replicator.
- Other minor improvements.
See changelog for the 2.1.x branch for more:
http://docs.couchdb.org/en/latest/whatsnew/2.1.html
- The build system embeds the Erlang VM into the package, which means that
the PLIST may differ across build systems. Hence why we use a semi-dynamic
PLIST here.
- That also means that lang/erlang is now a build dependency only.
- Include a couch-epmd service for the Erlang Port Mapper Daemon using the
embedded binary.
- Basic RCD script added.
Upstream changes since 1.6.x:
- Native clustering is now supported. Rather than use CouchDB replication
between multiple, distinct CouchDB servers, configure a cluster of CouchDB
nodes.
- Futon replaced by brand-new, completely re-engineered Fauxton interface.
URL remains the same.
- The new Mango Query Server provides a simple JSON-based way to perform
CouchDB queries without JavaScript or MapReduce.
- Mango selectors can be used in _changes feeds instead of JavaScript
MapReduce filters. Mango has been tested to be up to an order of magnitude
(10x) faster than JavaScript in this application.
- Rewrite rules for URLs can be performed using JavaScript functions.
- Multiple queries can be made of a view with a single HTTP request.
- Views can be queried with sorting turned off ( sorted=false) for a
performance boost.
- The global changes feed has been enhanced. It is now resumable and
persistent.
- New endpoints added (documentation forthcoming):
- /_membership shows all nodes in a cluster
- /_bulk_get speeds up the replication protocol over low-latency connections
- /_node/ api to access individual nodes' configuration and compaction
features
- /_cluster_setup api to set up a cluster from scratch.
- /_up api to signal health of a node to a load-balancer
- /db/_local_docs and /db/_design_docs (similar to /db/_all_docs)
- "Backend" interface on port 5986 used for specific cluster admin tasks. Of
interest are the _nodes and _dbs databases visible only through this
interface.
- Support added for Erlang/OTP 17.x, 18.x and 19
- New streamlined build system written for Unix-like systems and Microsoft
Windows
Upgrade Notes
- The update sequences returned by the /db/_changes feed are no longer
integers. They can be any JSON value. Applications should treat them as
opaque values and return them to CouchDB as-is.
- Temporary views are no longer supported.
- It is possible to have multiple replicator databases. replicator/db config
option has been removed. Instead _replicator and any database names ending
with the /_replicator suffix will be recognized as replicator databases by
the system.
- Note that the semantics of some API calls have changed due to the
introduction of the clustering feature. Specifically, make note of the
difference between receiving a 201 and a 202 when storing a document.
- all_or_nothing is no longer supported by the bulk_docs API

the amount of UUIDs that can be requested from the /_uuids handler
in a single request (CVE 2014-2668).

in the _replicator database, store the failure reason in the document.

Apache CouchDB is a distributed, fault-tolerant and schema-free document-
oriented database accessible via a RESTful HTTP/JSON API. Among other
features, it provides robust, incremental replication with bi-directional
conflict detection and resolution, and is queryable and indexable using
a table-oriented view engine with JavaScript acting as the default view
definition language.
CouchDB is written in Erlang, but can be easily accessed from any
environment that provides means to make HTTP requests. There are
a multitude of third-party client libraries that make this even easier
for a variety of programming languages and environments.
