        ## Getting Started
        
        ### Installing the SDK
        
        The SDK is available through [PyPi](https://pypi.python.org/pypi?name=optimizely-sdk&:action=display).
        
        To install:
        
            pip install optimizely-sdk
        
        ### Feature Management Access
        
        To access the Feature Management configuration in the Optimizely
        dashboard, please contact your Optimizely account executive.
        
        ### Using the SDK
        
        You can initialize the Optimizely instance in three ways: with a datafile, by providing an sdk_key, or by providing an implementation of
        [BaseConfigManager](https://github.com/optimizely/python-sdk/tree/master/optimizely/config_manager.py#L32).
        Each method is described below.
        
        1.  Initialize Optimizely with a datafile. This datafile will be used as
            the source of ProjectConfig throughout the life of Optimizely instance:
        
                optimizely.Optimizely(
                  datafile
                )
        
        2.  Initialize Optimizely by providing an \'sdk_key\'. This will
            initialize a PollingConfigManager that makes an HTTP GET request to
            the URL (formed using your provided sdk key and the
            default datafile CDN URL template) to asynchronously download the
            project datafile at regular intervals and update ProjectConfig when
            a new datafile is received. A hard-coded datafile can also be
            provided along with the sdk_key that will be used
            initially before any update:
        
                optimizely.Optimizely(
                  sdk_key='put_your_sdk_key_here'
                )
        
            If providing a datafile, the initialization will look like:
        
                optimizely.Optimizely(
                  datafile=datafile,
                  sdk_key='put_your_sdk_key_here'
                )
        
        3.  Initialize Optimizely by providing a ConfigManager that implements
            [BaseConfigManager](https://github.com/optimizely/python-sdk/tree/master/optimizely/config_manager.py#L34).
            You may use our [PollingConfigManager](https://github.com/optimizely/python-sdk/blob/master/optimizely/config_manager.py#L150) or
            [AuthDatafilePollingConfigManager](https://github.com/optimizely/python-sdk/blob/master/optimizely/config_manager.py#L375) as needed:
        
                optimizely.Optimizely(
                  config_manager=custom_config_manager
                )
        
        #### PollingConfigManager
        
        The [PollingConfigManager](https://github.com/optimizely/python-sdk/blob/master/optimizely/config_manager.py#L150) asynchronously polls for
        datafiles from a specified URL at regular intervals by making HTTP requests.
        
            polling_config_manager = PollingConfigManager(
                sdk_key=None,
                datafile=None,
                update_interval=None,
                url=None,
                url_template=None,
                logger=None,
                error_handler=None,
                notification_center=None,
                skip_json_validation=False
            )
        
        **Note**: You must provide either the sdk_key or URL. If
        you provide both, the URL takes precedence.
        
        **sdk_key** The sdk_key is used to compose the outbound
        HTTP request to the default datafile location on the Optimizely CDN.
        
        **datafile** You can provide an initial datafile to bootstrap the
        `ProjectConfigManager` so that it can be used immediately. The initial
        datafile also serves as a fallback datafile if HTTP connection cannot be
        established. The initial datafile will be discarded after the first
        successful datafile poll.
        
        **update_interval** The update_interval is used to specify a fixed
        delay in seconds between consecutive HTTP requests for the datafile.
        
        **url** The target URL from which to request the datafile.
        
        **url_template** A string with placeholder `{sdk_key}` can be provided
        so that this template along with the provided sdk key is
        used to form the target URL.
        
        You may also provide your own logger, error_handler, or
        notification_center.
        
        #### AuthDatafilePollingConfigManager
        
        The [AuthDatafilePollingConfigManager](https://github.com/optimizely/python-sdk/blob/master/optimizely/config_manager.py#L375)
        implements `PollingConfigManager` and asynchronously polls for authenticated datafiles from a specified URL at regular intervals
        by making HTTP requests.
        
            auth_datafile_polling_config_manager = AuthDatafilePollingConfigManager(
                datafile_access_token,
                *args,
                **kwargs
            )
        
        **Note**: To use [AuthDatafilePollingConfigManager](#authdatafilepollingconfigmanager), you must create a secure environment for
        your project and generate an access token for your datafile.
        
        **datafile_access_token** The datafile_access_token is attached to the outbound HTTP request header to authorize the request and fetch the datafile.
        
        #### Advanced configuration
        
        The following properties can be set to override the default
        configurations for [PollingConfigManager](#pollingconfigmanager) and [AuthDatafilePollingConfigManager](#authdatafilepollingconfigmanager).
        
        | **Property Name** |                                                                                    **Default Value**                                                                                    |                        **Description**                         |

        |     datafile      |                                                                                          None                                                                                           | Initial datafile, typically sourced from a local cached source |
        |  update_interval  |                                                                                        5 minutes                                                                                        |          Fixed delay between fetches for the datafile          |
        |        url        |                                                                                          None                                                                                           |      Custom URL location from which to fetch the datafile      |
        |   url_template    | `PollingConfigManager:`<br/>https://cdn.optimizely.com/datafiles/{sdk_key}.json<br/>`AuthDatafilePollingConfigManager:`<br/>https://config.optimizely.com/datafiles/auth/{sdk_key}.json |             Parameterized datafile URL by SDK key              |
        
        A notification signal will be triggered whenever a _new_ datafile is
        fetched and Project Config is updated. To subscribe to these
        notifications, use:
        
        ```
        notification_center.add_notification_listener(NotificationTypes.OPTIMIZELY_CONFIG_UPDATE, update_callback)
        ```
        
        For Further details see the Optimizely [Full Stack documentation](https://docs.developers.optimizely.com/full-stack/docs)
        to learn how to set up your first Python project and use the SDK.
        
        ## Development
        
        ### Building the SDK
        
        Build and install the SDK with pip, using the following command:
        
            pip install -e .
        
        ### Unit tests
        
        #### Running all tests
        
        To get test dependencies installed, use a modified version of the
        install command:
        
            pip install -e .[test]
        
        You can run all unit tests with:
        
            pytest
        
        #### Running all tests in a file
        
        To run all tests under a particular test file you can use the following
        command:
        
            pytest tests.<file_name_without_extension>
        
        For example, to run all tests under `test_event_builder`, the command would be:
        
            pytest tests/test_event_builder.py
        
        #### Running all tests under a class
        
        To run all tests under a particular class of tests you can use the
        following command:
        
            pytest tests/<file_name_with_extension>::ClassName
        
        For example, to run all tests under `test_event_builder.EventTest`, the command
        would be:
        
            pytest tests/test_event_builder.py::EventTest
        
        #### Running a single test
        
        To run a single test you can use the following command:
        
            pytest tests/<file_name_with_extension>::ClassName::test_name
        
        For example, to run `test_event_builder.EventTest.test_init`, the command
        would be:
        
            pytest tests/test_event_builder.py::EventTest::test_init

        # Optimizely Python SDK Changelog
        
        ## 3.5.0
        July 9th, 2020
        
        ### New Features:
        * Introduced 2 APIs to interact with feature variables:
          * `get_feature_variable_json` allows you to get value for JSON variables related to a feature.
          * `get_all_feature_variables` gets values for all variables under a feature.
        * Added support for fetching authenticated datafiles. `AuthDatafilePollingConfigManager` is a new config manager that allows you to poll for a datafile belonging to a secure environment. You can create a client by setting the `datafile_access_token`.
        
        ### Bug Fixes:
        * Fixed log messages for targeted rollouts evaluation. ([#268](https://github.com/optimizely/python-sdk/pull/268))
        
        ## 3.4.2
        June 11th, 2020
        
        ### Bug Fixes:
        * Adjusted log level for audience evaluation logs. ([#267](https://github.com/optimizely/python-sdk/pull/267))
        
        ## 3.4.1
        March 19th, 2020
        
        ### Bug Fixes:
        * Updated `jsonschema` to address [installation issue](https://github.com/optimizely/python-sdk/issues/232).
        
        ## 3.4.0
        January 27th, 2020
        
        ### New Features:
        * Added a new API to get project configuration static data.
          * Call `get_optimizely_config()` to get a snapshot of 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 `get_optimizely_config()` - `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-python](https://docs.developers.optimizely.com/full-stack/docs/optimizelyconfig-python).
        
        
        ## 3.3.1
        December 16th, 2019
        
        ### Bug Fixes:
        * Fixed [installation issue](https://github.com/optimizely/python-sdk/issues/220) on Windows. ([#224](https://github.com/optimizely/python-sdk/pull/224))
        * Fixed batch event processor deadline reset issue. ([#227](https://github.com/optimizely/python-sdk/pull/227))
        * Added more batch event processor debug messages. ([#227](https://github.com/optimizely/python-sdk/pull/227))
        
        ## 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](https://github.com/optimizely/python-sdk/blob/3.3.x/optimizely/event/event_processor.py#L45).
          * 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](https://github.com/optimizely/python-sdk/pull/217))
        
        ## 3.2.0
        August 27th, 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):
          * The [PollingConfigManager](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).
          * 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) or the [PollingConfigManager](https://github.com/optimizely/python-sdk/blob/3.2.x/optimizely/config_manager.py#L151). Refer to the [README](README.md) 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_UPDATE notification listener.
        * Introduced `Optimizely.get_feature_variable` API.  ([#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))
        * `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))
        
        ## 3.2.0b1

          * 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_UPDATE notification listener.
        * Introduced `Optimizely.get_feature_variable` API.  ([#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))
        * `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))
        
        ## 3.1.0
        May 3rd, 2019
        
        ### New Features:
        * Introduced Decision notification listener to be able to record:
          * Variation assignments for users activated in an experiment.
          * Feature access for users.
          * Feature variable value for users.
        
        ### Bug Fixes:
        * Feature variable APIs now return default variable value when featureEnabled property is false.  ([#171](https://github.com/optimizely/python-sdk/pull/171))
        
        ### Deprecated:
        * Activate notification listener is deprecated as of this release.  Recommendation is to use the new Decision notification listener.  Activate notification listener will be removed in the next major release.
        
        ## 3.0.0
        March 1st, 2019
        
        The 3.0 release improves event tracking and supports additional audience
        targeting functionality.
        
        ### New Features:
        * Event tracking:
          * The `track` method now dispatches its conversion event *unconditionally*, without first determining whether the user is targeted by a known experiment that uses the event. This may increase outbound network traffic.
          * In Optimizely results, conversion events sent by 3.0 SDKs don\'t explicitly name the experiments and variations that are currently targeted to the user. Instead, conversions are automatically attributed to variations that the user has previously seen, as long as those variations were served via 3.0 SDKs or by other clients capable of automatic attribution, and as long as our backend actually received the impression events for those variations.
          * Altogether, this allows you to track conversion events and attribute them to variations even when you don't know all of a user's attribute values, and even if the user's attribute values or the experiment's configuration have changed such that the user is no longer affected by the experiment. As a result, **you may observe an increase in the conversion rate for previously-instrumented events.** If that is undesirable, you can reset the results of previously-running experiments after upgrading to the 3.0 SDK.  -   This will also allow you to attribute events to variations from other Optimizely projects in your account, even though those experiments don't appear in the same datafile.
          * Note that for results segmentation in Optimizely results, the user attribute values from one event are automatically applied to all other events in the same session, as long as the events in question were actually received by our backend. This behavior was already in place and is not affected by the 3.0 release.
        * Support for all types of attribute values, not just strings.
          * All values are passed through to notification listeners.
          * Strings, booleans, and valid numbers are passed to the event dispatcher and can be used for Optimizely results segmentation.  A valid number is a finite float or numbers.Integral in the inclusive range \[-2 ^ 53, 2 ^ 53\].
          * Strings, booleans, and valid numbers are relevant for audience conditions.
        * Support for additional matchers in audience conditions:
          * An `exists` matcher that passes if the user has a non-null value for the targeted user attribute and fails otherwise.
          * A `substring` matcher that resolves if the user has a string value for the targeted attribute.
            * `gt` (greater than) and `lt` (less than) matchers that resolve if the user has a valid number value for the targeted attribute.  A valid number is a finite float or numbers.Integral in the inclusive range \[-2 ^ 53, 2 ^ 53\].
            * The original (`exact`) matcher can now be used to target booleans and valid numbers, not just strings.
        * Support for A/B tests, feature tests, and feature rollouts whose audiences are combined using `"and"` and `"not"` operators, not just the `"or"` operator.
        * Datafile-version compatibility check: The SDK will remain uninitialized (i.e., will gracefully fail to activate experiments and features) if given a datafile version greater than 4.
        * Updated Pull Request template and commit message guidelines.
        
        ### Breaking Changes:
        * Conversion events sent by 3.0 SDKs don\'t explicitly name the experiments and variations that are currently targeted to the user, so these events are unattributed in raw events data export. You must use the new *results* export to determine the variations to which events have been attributed.
        * Previously, notification listeners were only given string-valued user attributes because only strings could be passed into various method calls. That is no longer the case. You may pass non-string attribute values, and if you do, you must update your notification listeners to be able to receive whatever values you pass in.
        
        ### Bug Fixes:
        * Experiments and features can no longer activate when a negatively targeted attribute has a missing, null, or malformed value.
          * Audience conditions (except for the new `exists` matcher) no longer resolve to `false` when they fail to find an legitimate value for the targeted user attribute. The result remains `null` (unknown). Therefore, an audience that negates such a condition (using the `"not"` operator) can no longer resolve to `true` unless there is an unrelated branch in the condition tree that itself resolves to `true`.
        * Updated the default event dispatcher to log an error if the request resolves to HTTP 4xx or 5xx.  ([#140](https://github.com/optimizely/python-sdk/pull/140))
        * All methods now validate that user IDs are strings and that experiment keys, feature keys, feature variable keys, and event keys are non-empty strings.
        
        ## 2.1.1
        August 21st, 2018
        
        * Fix: record conversions for all experiments using an event when using track([#136](https://github.com/optimizely/python-sdk/pull/136)).
        
        ## 2.1.0
        July 2nd, 2018
        
        * Introduced support for bot filtering ([#121](https://github.com/optimizely/python-sdk/pull/121)).
        * Overhauled logging to use standard Python logging ([#123](https://github.com/optimizely/python-sdk/pull/123)).
        
        ## 2.0.1
        June 19th, 2018
        
        * Fix: send impression event for Feature Test when Feature is disabled ([#128](https://github.com/optimizely/python-sdk/pull/128)).
        
        ## 2.0.0
        April 12th, 2018
        
        This major release introduces APIs for Feature Management. It also
        introduces some breaking changes listed below.
        
        ### New Features
        * Introduced the `is_feature_enabled` API to determine whether to show a feature to a user or not.
        
        ```
            is_enabled = optimizel_client.is_feature_enabled('my_feature_key', 'my_user', user_attributes)
        ```
        
        * All enabled features for the user can be retrieved by calling:
        
        ```
            enabled_features = optimizely_client.get_enabled_features('my_user', user_attributes)
        ```
        * Introduced Feature Variables to configure or parameterize a feature.  There are four variable types: `String`, `Integer`, `Double`, `Boolean`.
        
        ```
            string_variable = optimizely_client.get_feature_variable_string('my_feature_key', 'string_variable_key', 'my_user')
            integer_variable = optimizely_client.get_feature_variable_integer('my_feature_key', 'integer_variable_key', 'my_user')
            double_variable = optimizely_client.get_feature_variable_double('my_feature_key', 'double_variable_key', 'my_user')
            boolean_variable = optimizely_client.get_feature_variable_boolean('my_feature_key', 'boolean_variable_key', 'my_user')
        ```
        
        ### Breaking changes
        * The `track` API with revenue value as a stand-alone parameter has been removed. The revenue value should be passed in as an entry in the event tags dict. The key for the revenue tag is `revenue` and the passed in value will be treated by Optimizely as the value for computing results.
        
        ```
            event_tags = {
              'revenue': 1200
            }
        
            optimizely_client.track('event_key', 'my_user', user_attributes, event_tags)
        ```
