posthog

7.14.0 — 2026-05-01

Minor changes

• 69dc2a8 Add evaluate_flags() and a new flags option on capture() so a single /flags call can power both flag branching and event enrichment per request:

  flags = posthog.evaluate_flags(distinct_id, person_properties={"plan": "enterprise"})
  if flags.is_enabled("new-dashboard"):
      render_new_dashboard()
  posthog.capture("page_viewed", distinct_id=distinct_id, flags=flags)

  The returned FeatureFlagEvaluations snapshot exposes is_enabled(), get_flag(), get_flag_payload() for branching and only_accessed() / only([keys]) filter helpers. Pass flag_keys=[...] to evaluate_flags() to scope the underlying /flags request itself.

  Deprecates feature_enabled(), get_feature_flag(), get_feature_flag_payload(), and capture(send_feature_flags=...). They continue to work but now emit a DeprecationWarning pointing at evaluate_flags(). Removal is planned for the next major version. — Thanks @dmarticus!

fix: extract model from response for OpenAI stored prompts

When using OpenAI stored prompts, the model is defined in the OpenAI dashboard rather than passed in the API request. This fix adds a fallback to extract the model from the response object when not provided in kwargs, ensuring generations show up with the correct model and enabling cost calculations.

Feature flag API requests now automatically retry on transient failures:

• Network errors (connection refused, DNS failures, timeouts)

6.0.1

• fix: response $process_person_profile property when passed to capture

6.0.0

This release contains a number of major breaking changes:

• feat: make distinct_id an optional parameter in posthog.capture and related functions
• feat: make capture and related functions return Optional[str], which is the UUID of the sent event, if it was sent
• fix: remove identify (prefer posthog.set()), and page and screen (prefer posthog.capture())
• fix: delete exception-capture specific integrations module. Prefer the general-purpose django middleware as a replacement for the django Integration.

To migrate to this version, you'll mostly just need to switch to using named keyword arguments, rather than positional ones. For example:

# Old calling convention
posthog.capture("user123", "button_clicked", {"button_id": "123"})
# New calling convention
posthog.capture(distinct_id="user123", event="button_clicked", properties={"button_id": "123"})

# Better pattern
with posthog.new_context():
    posthog.identify_context("user123")

    # The event name is the first argument, and can be passed positionally, or as a keyword argument in a later position
    posthog.capture("button_pressed")

Generally, arguments are now appropriately typed, and docstrings have been updated. If something is unclear, please open an issue, or submit a PR!

4.0.1 – 2025-04-29

1. Remove deprecated monotonic library. Use Python's core time.monotonic function instead
2. Clarify Python 3.9+ is required

4.0.0 - 2025-04-24

1. Added new method get_feature_flag_result which returns a FeatureFlagResult object. This object breaks down the result of a feature flag into its enabled state, variant, and payload. The benefit of this method is it allows you to retrieve the result of a feature flag and its payload in a single API call. You can call get_value on the result to get the value of the feature flag, which is the same value returned by get_feature_flag (aka the string variant if the flag is a multivariate flag or the boolean value if the flag is a boolean flag).

Example:

result = posthog.get_feature_flag_result("my-flag", "distinct_id")
print(result.enabled)     # True or False
print(result.variant)     # 'the-variant-value' or None
print(result.payload)     # {'foo': 'bar'}
print(result.get_value()) # 'the-variant-value' or True or False
print(result.reason)      # 'matched condition set 2' (Not available for local evaluation)

Breaking change:

1. get_feature_flag_payload now deserializes payloads from JSON strings to Any. Previously, it returned the payload as a JSON encoded string.

Before:

payload = get_feature_flag_payload('key', 'distinct_id') # "{\"some\": \"payload\"}"

After:

payload = get_feature_flag_payload('key', 'distinct_id') # {"some": "payload"}

1. Remove "-api" suffix from ingestion hostnames

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:

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.
