16.7.2 (Nov 30 2020)edit

16.7.1 (Mar 26 2020)edit

16.7.0 (Mar 25 2020)edit

  • apiVersion "7.6" is now the default
  • "7.6" is now the only apiVersion in the version 7 major version

  • apiVersion "7.3" is now the default

16.3.0 (Jul 10 2019)edit

  • Removed many development dependencies
  • Switched to standard + prettier linting config. Testing indicates that this doesn’t have any effect on the external API but it produces thousands of changes so releasing as a minor version bump just to be safe.

16.2.0 (Jul 3 2019)edit

  • apiVersion "7.2" is now the default
  • Dropped support for old 6.7 version

16.1.1 (Jun 4 2019)edit

  • Upgrade from lodash 2 to lodash 4 (Thanks @dominykas!) #600

    • Because this is such a large shift, and it could have potentially subtle effects on the module, we’ve done a major version bump. Unless you are using custom plugins that rely on the old utils, this should be the equivalent of a patch upgrade.

  • "console" reporter is now available in Node.js for environments where that is preferred to "stdout" #523

  • minor changes to apiVersion will no longer be released as a major release

    • When we decided to have elasticsearch-js support multiple version of Elasticsearch, we included an apiVersion configuration paramter for users to choose the API that each client should expose. This setting had a default value that matched the most recent version of Elasticsearch at the time of release. Since Elasticsearch didn’t make specific guarantees about backwards compatibility elasticsearch-js released a new major version every time the default apiVersion changed.

      Elasticsearch now guarantees backwards compatibility within a specific major version, and has for a while, (See "Types of Releases") so starting in 13.0, changes to the default apiVersion that are within the same major version of Elasticsearch will be released as minor version updates. This means that when Elasticsearch 5.3 is released, elasticsearch-js will release a new 13.x version, and when Elasticsearch 6.0 is released, elasticsearch-js will release a major update (14.0, or similar).

  • all but the latest apiVersion options from the 1.x and 2.x line have been removed

    • Elasticsearch-js ships with individual API definitions for every minor version of Elasticsearch, leading to the library becoming unnecessarily large. In an effort to find a compromise between size and ease of use elasticsearch-js now only ships with apiVersion options for the latest minor release of Elasticsearch 1.x and 2.x (1.7 and 2.4 at this time).

      If you use an older version of Elasticsearch 1.x or 2.x, please consider upgrading to get the latest features and bug fixes (see section 7.1 of the support policy). If you cannot upgrade then you have two options:

      1. Use the apiVersion that matches the major version of your Elasticsearch install (1.4 ⇒ 1.7, 2.0 ⇒ 2.4, etc.). This definition may include new APIs or parameters that are mentioned in the docs but not actually available in your Elasticsearch version, but any methods or parameter you were using before 13.0 should work perfectly.

      2. Download the API definition file for the version you are using from the 12.1.1 source, and then attach it to the client like so:

        const elasticsearch = require('elasticsearch')
elasticsearch.Client.apis['1.4'] = require('./1_4.js'); // downloaded from https://git.io/vDE7w

const client = new elasticsearch.Client({
  apiVersion: '1.4'
})
