Java-SDK - 3.2.0
## 3.2.0 June 26th, 2019
### New Features: - Added support for automatic datafile management via `HttpProjectConfigManager`: - The [`HttpProjectConfigManager`](https://github.com/optimizely/java-sdk/blob/master/core-httpclient-impl/src/main/java/com/optimizely/ab/config/HttpProjectConfigManager.java) is part of the `core-httpclient-impl` package and is an implementation of the abstract [`PollingProjectConfigManager`](https://github.com/optimizely/java-sdk/blob/master/core-api/src/main/java/com/optimizely/ab/config/PollingProjectConfigManager.java) class. - Users must first build the `HttpProjectConfigManager` with an SDK key and then and provide that instance to the Optimizely.Builder. - An initial datafile can be provided to the `HttpProjectConfigManager` to bootstrap before making http requests for the hosted datafile. - Requests for the datafile are made in a separate thread and are scheduled with fixed delay. - Configuration updates can be subscribed to via the `Optimizely#addUpdateConfigNotificationHandler` or by subscribing to the NotificationCenter built with the `HttpProjectConfigManager`. - Added `AsyncEventHandler.Builder` to be consistent with other Optimizely resources. - The [`OptimizelyFactory`](https://github.com/optimizely/java-sdk/blob/master/core-httpclient-impl/src/main/java/com/optimizely/ab/OptimizelyFactory.java) was included in the `core-httpclient-impl` package and provides basic methods for instantiating the Optimizely SDK with a minimal number of parameters. - Default configuration options for `HttpProjectConfigManager` and `AsyncEventHandler` can be overwritten using Java system properties, environment variables or via an `optimizely.properties` file to avoid hard coding the configuration options.
### Deprecated - `Optimizely.builder(String, EventHandler)` was deprecated in favor of pure builder methods `withConfigManager` and `withEventHandler`.
