+
+## 3.5.0 - 2024-02-29
+
+1. - Adds a new `feature_flags_request_timeout_seconds` timeout parameter for feature flags which defaults to 3 seconds, updated from the default 10s for all other API calls.
+
+## 3.4.2 - 2024-02-20
+
+1. Add `historical_migration` option for bulk migration to PostHog Cloud.
+

+
+## 3.3.2 - 2024-01-19
+
+1. Return success/failure with all capture calls from module functions
+
+## 3.3.1 - 2024-01-10
+
+1. Make sure we don't override any existing feature flag properties when adding locally evaluated feature flag properties.
+
+## 3.3.0 - 2024-01-09
+
+1. When local evaluation is enabled, we automatically add flag information to all events sent to PostHog, whenever possible. This makes it easier to use these events in experiments.
+
+## 3.2.0 - 2024-01-09
+
+1. Numeric property handling for feature flags now does the expected: When passed in a number, we do a numeric comparison. When passed in a string, we do a string comparison. Previously, we always did a string comparison.
+2. Add support for relative date operators for local evaluation.
+
+## 3.1.0 - 2023-12-04
+
+1. Increase maximum event size and batch size
+
+## 3.0.2 - 2023-08-17
+
+1. Returns the current flag property with $feature_flag_called events, to make it easier to use in experiments
+
+## 3.0.1 - 2023-04-21
+
+1. Restore how feature flags work when the client library is disabled: All requests return `None` and no events are sent when the client is disabled.
+2. Add a `feature_flag_definitions()` debug option, which returns currently loaded feature flag definitions. You can use this to more cleverly decide when to request local evaluation of feature flags.
+
+## 3.0.0 - 2023-04-14
+
+Breaking change:
+
+All events by default now send the `$geoip_disable` property to disable geoip lookup in app. This is because usually we don't
+want to update person properties to take the server's location.
+
+The same now happens for feature flag requests, where we discard the IP address of the server for matching on geoip properties like city, country, continent.
+
+To restore previous behaviour, you can set the default to False like so:
+
+```python
+posthog.disable_geoip = False
+
+# // and if using client instantiation:
+posthog = Posthog('api_key', disable_geoip=False)
+
+```
+
+## 2.5.0 - 2023-04-10
+
+1. Add option for instantiating separate client object
+
+## 2.4.2 - 2023-03-30
+
+1. Update backoff dependency for posthoganalytics package to be the same as posthog package
+
+## 2.4.1 - 2023-03-17
+
+1. Removes accidental print call left in for decide response
+
+## 2.4.0 - 2023-03-14
+
+1. Support evaluating all cohorts in feature flags for local evaluation
+
+## 2.3.1 - 2023-02-07
+
+1. Log instead of raise error on posthog personal api key errors
+2. Remove upper bound on backoff dependency
+
+## 2.3.0 - 2023-01-31
+
+1. Add support for returning payloads of matched feature flags
+
+## 2.2.0 - 2022-11-14
+
+Changes:
+
+1. Add support for feature flag variant overrides with local evaluation
+
+## 2.1.2 - 2022-09-15
+
+Changes:
+
+1. Fixes issues with date comparison.
+
+## 2.1.1 - 2022-09-14
+
+Changes:
+
+1. Feature flags local evaluation now supports date property filters as well. Accepts both strings and datetime objects.
+
+## 2.1.0 - 2022-08-11
+
+Changes:
+
+1. Feature flag defaults have been removed
+2. Setup logging only when debug mode is enabled.
+
+## 2.0.1 - 2022-08-04
+
+- Make poll_interval configurable
+- Add `send_feature_flag_events` parameter to feature flag calls, which determine whether the `$feature_flag_called` event should be sent or not.
+- Add `only_evaluate_locally` parameter to feature flag calls, which determines whether the feature flag should only be evaluated locally or not.
+
+## 2.0.0 - 2022-08-02
+
+Breaking changes:
+
+1. The minimum version requirement for PostHog servers is now 1.38. If you're using PostHog Cloud, you satisfy this requirement automatically.
+2. Feature flag defaults apply only when there's an error fetching feature flag results. Earlier, if the default was set to `True`, even if a flag resolved to `False`, the default would override this.
+   **Note: These are removed in 2.0.2**
+3. Feature flag remote evaluation doesn't require a personal API key.
+
+New Changes:
+
+1. You can now evaluate feature flags locally (i.e. without sending a request to your PostHog servers) by setting a personal API key, and passing in groups and person properties to `is_feature_enabled` and `get_feature_flag` calls.
+2. Introduces a `get_all_flags` method that returns all feature flags. This is useful for when you want to seed your frontend with some initial flags, given a user ID.
+
+## 1.4.9 - 2022-06-13
+
+- Support for sending feature flags with capture calls
+
+## 1.4.8 - 2022-05-12
+
+- Support multi variate feature flags
+
+## 1.4.7 - 2022-04-25
+
+- Allow feature flags usage without project_api_key
+
 ## 1.4.1 - 2021-05-28
+
 - Fix packaging issues with Sentry integrations
 
 ## 1.4.0 - 2021-05-18
