CouchDB 1.3.0 Adds New Features and Algorithm Enhancements
CouchDB 1.3.0 has been released by Apache Software Foundation with support for Fix _session for IE7, Cross Origin Resource Sharing (CORS) and also limits recursion depth for the maximum of 100 invocations in the URL rewriter. It no longer rewrites the X-CouchDB-Requested-Path during recursive calls to the rewriter and also adds Server-Sent Events protocol to db changes API. Moreover, the latest release also enables you to make password hashing synchronous when using the /_config/admins API and includes user name in show/list ETags.
CouchDB 1.3.0 provides solution for the unnecessary conflict when you create and delete a document in the same batch and the replicator included with the database will make use of a new server-wide UUID in checkpoint IDs to improve the chances of an efficient resume. It also moved the JS test suite to the CLI with improved trackbacks and test reliability.
The recent release has disabled the link to the Futon test suite and also added view request duration to Futon in addition to disabling those buttons for which user doesn't have permissions. Moreover, Autoconf v2.63 is required if you build from Git checkout directly. According to official sources, Futon test suite causes problems when run from a web browser and hence has been made available via the CLI.
In CouchDB 1.3.0, passwords are hashed using PBKDF2 (Password-Based Key Derivation Function 2) algorithm with a configurable work factor and provides support for utc_id algorithm. Moreover, the database name is encoded during rewriting with improved C/C++ compiler detection. It also resets rewrite counter on new request and also fixes an issue where stopped status returns before process exits in couchdb script.
CouchDB 1.3.0 includes pre-built packages for Windows and OS X in addition to a manual that is hosted directly out of Futon. Apache also provides manual in PDF format along with the installation package.
