\## 3.2.0
July 22nd, 2019

\### New Features:
\* Added support for automatic datafile management via \`HttpProjectConfigManager\` for framework 4.0 or above:
\* The \[\`HttpProjectConfigManager\`]\([https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/HttpProjectConfigManager.cs](https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/HttpProjectConfigManager.cs)) is an implementation of the abstract
\[\`PollingProjectConfigManager\`]\([https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/PollingProjectConfigManager.cs](https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/PollingProjectConfigManager.cs)) class.
\- Users must first build the \`HttpProjectConfigManager\` with an SDK key and then and provide that instance to the \`Optimizely\` instance.
\- 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 NotificationCenter built with the \`HttpProjectConfigManager\`.
\- \`Optimizely\` instance must be disposed after the use or \`HttpProjectConfigManager\` must be disposed after the use to release resources.
\* The \[\`OptimizelyFactory\`]\([https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/OptimizelyFactory.cs](https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/OptimizelyFactory.cs)) provides basic methods for instantiating the Optimizely SDK with a minimal number of parameters. Check \[\`README.md\`]\([https://github.com/optimizely/csharp-sdk#use-optimizelyfactory](https://github.com/optimizely/csharp-sdk#use-optimizelyfactory)) for more details.
