Release 3.3.0

[3.3.0] - October 28th, 2019

New Features:

• Added support for event batching via the event processor.
  • Events generated by methods like activate, track, and is_feature_enabled will be held in a queue until the configured batch size is reached, or the configured flush interval has elapsed. Then, they will be batched into a single payload and sent to the event dispatcher.
  • To configure event batching, set the batch_size and flush_interval properties when initializing instance of BatchEventProcessor.
  • Event batching is disabled by default. You can pass in instance of BatchEventProcessor when creating Optimizely instance to enable event batching.
  • Users can subscribe to LogEvent notification to be notified of whenever a payload consisting of a batch of user events is handed off to the event dispatcher to send to Optimizely's backend.
• Introduced blocking timeout in PollingConfigManager. By default, calls to get_config will block for maximum of 10 seconds until config is available.

Bug Fixes:

• Fixed incorrect log message when numeric metric is not used. (#217)
