Release 3.9.1

Bug Fixes:

• Duplicate experiment key issue with multiple feature flags. While trying to get variation from the variationKeyMap, it was unable to find because the latest experimentKey was overriding the previous one. #267

3.9.0

Bug Fixes:

• When no error handler is given for HttpProjectConfigManager, then default error handler should be used without raise exception. #260
• .Net Standard 2.0 was missing Configuration manager library in nugget package. #262

3.8.0

• Introducing a new primary interface for retrieving feature flag status, configuration and associated experiment decisions for users (#248, #250, #251, #253, #254, #255, #256, #257, #258). The new OptimizelyUserContext class is instantiated with CreateUserContext and exposes the following APIs to get OptimizelyDecision:

January 23rd, 2020

New Features

• Added a new API to get project configuration static data.

  • It returns an OptimizelyConfig instance which includes a datafile revision number, all experiments, and feature flags mapped by their key values.
  • Added caching for GetOptimizelyConfig - OptimizelyConfig object will be cached and reused for the lifetime of the datafile
  • For details, refer to our documentation page: https://docs.developers.optimizely.com/full-stack/docs/optimizelyconfig-csharp.

• Blocking timeout was not being assigned. When not providing any value, it was just logging not setting up periodinterval and blocking timeout value. #202

Release 3.3.0

3.3.0

September 26th, 2019

New Features:

• Configuration manager is set to PollingProjectConfigManager and for datafile will be started by default. Requests to download and update datafile are made in a separate thread and are scheduled with fixed delay.
• Added support for event batching via the event processor.
• Events generated by methods like Activate, Track, and IsFeatureEnabled will be held in a queue until the configured batch size is reached, or the configured flush interval has elapsed. Then, they will be combined into a request and sent to the event dispatcher.
• To configure event batching, set the MaxEventBatchSize and MaxEventFlushInterval properties in the OptimizelyFactory using OptimizelyFactory.SetBatchSize(int batchSize) and OptimizelyFactory.SetFlushInterval(TimeSpan flushInterval) and then creating using OptimizelyFactory.NewDefaultInstance.
• Event batching is enabled by default. eventBatchSize defaults to 10. eventFlushInterval defaults to 30000 milliseconds.
• Updated the Dispose method representing the process of closing the instance. When Dispose is called, any events waiting to be sent as part of a batched event request will be immediately batched and sent to the event dispatcher.
• If any such requests were sent to the event dispatcher, Stop waits for provided TimeoutInterval before stoping, so that events get successfully dispatched.
• OptimizelyFactory now provides support of setting configuration variables from App.config, User will now be able to provide configuration variables of HttpConfigManager and BatchEventProcessor in App.config. Steps of usage are provided in README.md.

Deprecated

• EventBuilder was deprecated and now we will be using UserEventFactory and EventFactory to create LogEvent Object.
• Deprecated Track notifications in favor of explicit LogEvent notification.
• New features will no longer be supported on .net standard 1.6 and .net 3.5
