+## 3.4.0 - 2024-02-05
+
+1. Point given hosts to new ingestion hosts
+
+## 3.3.4 - 2024-01-30
+
+1. Update type hints for module variables to work with newer versions of mypy
+
+## 3.3.3 - 2024-01-26
+
+1. Remove new relative date operators, combine into regular date operators
+
+## 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 `$feature_flag_called` event should be sent or not.
+- Add `only_evaluate_locally` parameter to feature flag calls, which determines whether the feature flag should only be evaluated locally or not.
+
+## 2.0.0 - 2022-08-02
+
+Breaking changes:
+
+1. The minimum version requirement for PostHog servers is now 1.38. If you're using PostHog Cloud, you satisfy this requirement automatically.
+2. Feature flag defaults apply only when there's an error fetching feature flag results. Earlier, if the default was set to `True`, even if a flag resolved to `False`, the default would override this. 
+**Note: These are removed in 2.0.2**
+3. Feature flag remote evaluation doesn't require a personal API key.
+
+New Changes:
+
+1. You can now evaluate feature flags locally (i.e. without sending a request to your PostHog servers) by setting a personal API key, and passing in groups and person properties to `is_feature_enabled` and `get_feature_flag` calls.
+2. Introduces a `get_all_flags` method that returns all feature flags. This is useful for when you want to seed your frontend with some initial flags, given a user ID.
+
+
+
+## 1.4.9 - 2022-06-13
+- Support for sending feature flags with capture calls
+
+## 1.4.8 - 2022-05-12
+- Support multi variate feature flags
+
+## 1.4.7 - 2022-04-25
+- Allow feature flags usage without project_api_key
+
+## 1.4.1 - 2021-05-28
+- Fix packaging issues with Sentry integrations
+
+## 1.4.0 - 2021-05-18
+
+- Improve support for `project_api_key` (#32)
+- Resolve polling issues with feature flags (#29)
+- Add Sentry (and Sentry+Django) integrations (#13)
+- Fix feature flag issue with no percentage rollout (#30)
+
+## 1.3.1 - 2021-05-07
+
+- Add `$set` and `$set_once` support (#23)
+- Add distinct ID to `$create_alias` event (#27)
+- Add `UUID` to `ID_TYPES` (#26)
+
+## 1.2.1 - 2021-02-05
+
+Initial release logged in CHANGELOG.md.

 # PostHog Python

-Please see the main [PostHog docs](https://posthog.com/docs).
+[![PyPI](https://img.shields.io/pypi/v/posthog)](https://pypi.org/project/posthog/)

-Specifically, the [Python integration](https://posthog.com/docs/integrations/python-integration) details.
+
+Please see the [Python integration docs](https://posthog.com/docs/integrations/python-integration) for details.
+
+## Development
+
+### Testing Locally
+
+1. Run `python3 -m venv env` (creates virtual environment called "env")
+2. Run `source env/bin/activate` (activates the virtual environment)
+3. Run `python3 -m pip install -e ".[test]"` (installs the package in develop mode, along with test dependencies)
+4. Run `make test`
+  1. To run a specific test do `pytest -k test_no_api_key`
+
+### Running Locally
+
+Assuming you have a [local version of PostHog](https://posthog.com/docs/developing-locally) running, you can run `python3 example.py` to see the library in action.
+
+### Running the Django Sentry Integration Locally
+
+There's a sample Django project included, called `sentry_django_example`, which explains how to use PostHog with Sentry.
+
+There's 2 places of importance (Changes required are all marked with TODO in the sample project directory)
+
+1. Settings.py
+    1. Input your Sentry DSN
+    2. Input your Sentry Org and ProjectID details into `PosthogIntegration()`
+    3. Add `POSTHOG_DJANGO` to settings.py. This allows the `PosthogDistinctIdMiddleware` to get the distinct_ids
+
+2. urls.py
+    1. This includes the `sentry-debug/` endpoint, which generates an exception
+
+To run things: `make django_example`. This installs the posthog-python library with the sentry-sdk add-on, and then runs the django app.
+Also start the PostHog app locally.
+Then navigate to `http://127.0.0.1:8080/sentry-debug/` and you should get an event in both Sentry and PostHog, with links to each other.
+
+### Releasing Versions
+
+Updated are released using GitHub Actions: after bumping `version.py` in `master` and adding to `CHANGELOG.md`, go to [our release workflow's page](https://github.com/PostHog/posthog-python/actions/workflows/release.yaml) and dispatch it manually, using workflow from `master`.

    Capture allows you to capture anything a user does within your system, which you can later use in PostHog to find patterns in usage, work out which features to improve or where people are giving up.

    A `capture` call requires

-    - `event name` to make sure
+    - `event name` to specify the event
    - We recommend using [verb] [noun], like `movie played` or `movie updated` to easily identify what your events mean later on.

    Optionally you can submit
    - `properties`, which can be a dict with any information you'd like to add
+    - `groups`, which is a dict of group type -> group key mappings

    For example:
    ```python
+    posthog.capture('distinct id', 'opened app')
    posthog.capture('distinct id', 'movie played', {'movie_id': '123', 'category': 'romcom'})
