\## 3.2.0-alpha
May 23rd, 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](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](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](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\`.
