See: http://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/configuration.html * Closing the client with `keepAlive` turned on will allow the process to exit. https://github.com/elastic/elasticsearch-js/issues/40 * Fixed a bug that caused invalid param/type errors to not be reported properly, in the browser builds that use promises * added the cat.threadPool to the master/1.0/1.x apis * Enabled Basic auth in the Angular connector -- Thanks @jeff-french! * Fixed a bug that was preventing index requests (and any other POST/PUT request) from using connections in the connection pool === 1.4 (Jan 30 2014) * The trace log messages will now diaplay the actual host connected to (without auth info) unless they are being written to a bash script * API Updated with latest changes awaiting 1.0 release === 1.2/1.3 (Jan 17 2014) * `apiVersion` config parameter was added.

Instead of being an object like `{body: ..., status: ...}` it is now just the response body === 1.0 (Dec 17 2013) * Initial Release === pre 1.0 * Another module, now know as es on npm, used the elasticsearch module name. This module had several pre-1.0 releases so we started at 1.0 to prevent collisions in exiting projects. The history for that project is available https://github.com/ncb000gt/node-es[here]
