\## \[3.2.0b1] - July 26th, 2019

\## New Features:

\- Added support for automatic datafile management via \[PollingConfigManager]\([https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config\_manager.py#L151](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L151)):
\- The \[PollingConfigManager]\([https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config\_manager.py#L151](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L151)) is an implementation of the \[BaseConfigManager]\([https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config\_manager.py#L32](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L32)).
\- Users may provide one of datafile or SDK key (\`sdk\_key\`) or both to \`optimizely.Optimizely\`. Based on that the SDK will use the \[StaticConfigManager]\([https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config\_manager.py#L73](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L73)) or the \[PollingConfigManager]\([https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config\_manager.py#L151](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L151)). Refer to the \[README]\([https://github.com/optimizely/python-sdk/blob/3.2.x/README.rst](https://github.com/optimizely/python-sdk/blob/3.2.x/README.rst)) for more instructions.
\- An initial datafile can be provided to the \`PollingConfigManager\` 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 by adding the Optimizely config notification.
\- Introduced \`Optimizely.get\_feature\_variable\` API. (\[#191]\([https://github.com/optimizely/python-sdk/pull/191](https://github.com/optimizely/python-sdk/pull/191)))

\## Deprecated:

\- NotificationCenter.clear\_notifications is deprecated as of this release. Please use \`NotificationCenter.clear\_notification\_listeners\`. (\[#182]\([https://github.com/optimizely/python-sdk/pull/182](https://github.com/optimizely/python-sdk/pull/182)))
\- \`NotificationCenter.clear\_all\_notifications\` is deprecated as of this release. Please use \`NotificationCenter.clear\_all\_notification\_listeners\`. (\[#182]\([https://github.com/optimizely/python-sdk/pull/182](https://github.com/optimizely/python-sdk/pull/182)))
