Release 4.0.0

[4.0.0] - April 30, 2020

New Features

• Removed lodash dependency
• ES module entry point for the browser - "module" property of package.json points to dist/optimizely.browser.es.min.js (#445)

Breaking Changes

• Removed Promise polyfill from browser entry point (417).
• Changed functionality of JSON schema validation in all entry points (442).
  • Previously, skipJSONValidation flag was used by the user to specify whether the JSON object should be validated.
  • Now, skipJSONValidation has been removed entirely from all entry points. Instead, a user will need to import jsonSchemaValidator from @optimizely/optimizely-sdk/dist/optimizely.json_schema_validator.min.js and pass it to createInstance to perform validation as shown below:

  const optimizelySDK = require('@optimizely/optimizely-sdk');
  const jsonSchemaValidator = require('@optimizely/optimizely-sdk/dist/optimizely.json_schema_validator.min');
  
  // Require JSON schema validation for the datafile
  var optimizelyClientInstance = optimizely.createInstance({
    datafile: datafile,
    jsonSchemaValidator: jsonSchemaValidator,
  });
