+# Migrating from posthog 7.x to 8.0
+
+posthog 8.0 sends every event through capture v1 and removes the legacy capture path.
+Most apps upgrade without code changes.
+Read the checklist first, then the sections that apply to you.
+
+## Checklist
+
+You need to change code if your app does any of these:
+
+- passes `Client` or `AsyncPosthog` constructor arguments by position after `host`
+- sets `capture_mode`, `POSTHOG_CAPTURE_MODE` or `gzip`
+- imports `CaptureV1Error`, `posthog.capture_v1`, `request.batch_post`, `EVENTS_ENDPOINT` or `AI_EVENTS_ENDPOINT`
+- sends events to a self-hosted PostHog that does not serve the capture v1 endpoints
+- reuses one event `uuid` for more than one event
+- sets `$process_person_profile` to turn person processing on for events without a distinct ID
+- passes strings such as `"true"` for `$cookieless_mode`, `$ignore_sent_at` or `$process_person_profile`
+- expects `super_properties` to override properties passed to a single call, including `$set` and `$groups`
+- sets `$is_server`, `$geoip_disable` or a system property such as `$os` and expects the SDK's value to win
+- tests the AI integrations with a mock client and asserts on `capture`
+- passes its own client object to the AI integrations
+
+## Endpoints
+
+| Method | Endpoint |
+| --- | --- |
+| `capture`, `set`, `set_once`, `alias`, `group_identify`, `capture_exception` | `/i/v1/analytics/events` |
+| `capture_ai`, `capture_ai_immediate`, and every built-in AI integration | `/i/v1/ai/events` |
+
+If you send events to a self-hosted PostHog, check that it serves both endpoints before you upgrade.
+An endpoint that is not served drops every event sent to it.
+
+## Removed options and APIs
+
+| Removed | Use instead |
+| --- | --- |
+| `capture_mode`, `CaptureMode`, `POSTHOG_CAPTURE_MODE` | Nothing. Capture v1 is the only path. Setting `posthog.capture_mode` on the module has no effect. |
+| `gzip=True` | `capture_compression=CaptureCompression.GZIP`. The default is no compression. `POSTHOG_CAPTURE_COMPRESSION` still works. |
+| `CaptureV1Error` (`from posthog.capture_v1 import CaptureV1Error`) | `CaptureError` (`from posthog import CaptureError`). There is no alias. |
+| `posthog.capture_v1` | `posthog.capture_event` and `posthog.capture_send` |
+| `request.batch_post`, `async_batch_post`, `EVENTS_ENDPOINT`, `AI_EVENTS_ENDPOINT` | Nothing. Send events through a client. |
+| The `gzip` parameter of `request.post` and `request.flags` | Nothing. |
+| The `backoff` dependency | Add it to your own requirements if your code imports it. |
+
+The `posthoganalytics` package has the same changes. For example, import `CaptureError` from `posthoganalytics`.
+
+Constructor arguments after `host` are keyword-only:
+
+```python
+# 7.x
+Posthog("<api_key>", "https://us.i.posthog.com", True)
+
+# 8.0
+Posthog("<api_key>", host="https://us.i.posthog.com", debug=True)
+```
+
+## Errors and `on_error`
+
+Capture v1 returns a result for every event, even when the request succeeds.
+An event can be dropped inside a 2xx response, for example when it is over a product quota.
+8.0 reports those events as failures.
+When the whole request is over the billing limit, capture returns a `402` with no per-event results instead.
+
+- Every capture failure is a `CaptureError`, a subclass of `APIError`. It has these fields:
+  - `status`: the HTTP status, or `0` when the request never got a response. With `0`, `__cause__` holds the network error. In 7.x, `on_error` received the raw `requests` exception.
+  - `endpoint`, `request_id` and `attempts`
+  - `drops`: `(uuid, details)` pairs for the events capture dropped in a 2xx response
+  - `retry_exhausted`: the uuids still waiting for a retry after the last attempt
+  - `event_results`: a `CaptureEventResult(result, details)` for each uuid that got a result in a 2xx response, from `posthog.capture_send`. An event missing from it never got a result.
+  - `verdict_summary()`: counts such as `drop/llm_events_over_quota=1, retry/not_persisted=1`
+- `on_error(error, batch)` receives every failure, including in `sync_mode` and from `AsyncPosthog.capture_immediate`.
+- With `on_error` set, the SDK logs nothing for a failed batch.
+- Without `on_error`, the SDK logs one line per failed batch, for example `2 event(s) not persisted by /i/v1/analytics/events: ...`. The line never contains event content or the server's response text.
+- The 7.x lines `error uploading: ...`, `async capture upload failed (...)` and `Immediate async capture failed (...)` are gone. Update any log-based alerts that match them.
+- In `sync_mode`, a failed `capture()` calls `on_error` and returns `None`. With `debug=True` it calls `on_error` and then re-raises the error.
+- If a capture inside `on_error` fails, the SDK logs the failure and does not call `on_error` again.
+- The SDK retries `408`, `500`, `502`, `503` and `504` responses and network errors. Other error statuses fail the batch at once, including `429` and the other 5xx codes. 7.x also retried `429` and every 5xx. Capture itself does not return `429`; a proxy in front of it can.
+- Retries start at 100 ms and double each attempt, up to 30 seconds. A `Retry-After` header sets a minimum wait, up to 30 seconds. The `Consumer` default is 3 retries, down from 10.
+
+## Event uuids
+
+- Each event needs its own uuid. Capture rejects a whole batch that contains the same uuid twice, so the other events in that batch are lost too.
+- The SDK accepts a uuid with hyphens, 32 hex digits, `{...}` braces or a `urn:uuid:` prefix, in any case. It sends the lowercase hyphenated form and returns that form from `capture`.
+- Any other value is replaced with a generated uuid, and the SDK logs an error. This applies to `AsyncPosthog` too.
+- Generated uuids are UUIDv7.
+
+## Session and window IDs
+
+Capture v1 sends `$session_id` and `$window_id` as top-level event fields, not as properties.
+The SDK moves them out of `properties` for you.
+
+- A string is sent as given, including `""`.
+- `None` counts as unset and is removed.
+- Any other value is removed and not sent, because capture would reject the whole batch. 7.x sent it as a property.
+
+## Event options
+
+Capture v1 sends processing options in an `options` object, next to `properties`.
+
+- `capture`, `capture_ai`, `set`, `set_once`, `alias`, `group_identify` and `capture_exception` take an `options` argument:
+
+  ```python
+  posthog.capture("signed_up", distinct_id="user-1", options={"cookieless_mode": True})
+  ```
+
+- `super_options`, a new `Client`, `AsyncPosthog` and module setting, sets options on every event, like `super_properties`.
+- `set_context_option(key, value)` sets an option for the current context, like `tag()`. `get_context_options()` returns the options of the current context. Both exist on `Client` and as module functions. `AsyncPosthog` has no context methods, like it has no `tag()`, so call the module functions. They apply to every client in the context.
+- Context tags and options reach `capture`, `capture_ai` and `capture_exception`. Context options also reach `set` and `set_once`. Neither reaches `alias` or `group_identify`. `super_properties` and `super_options` reach every method.
+- Options are sent as given. PostHog validates them.
+- An `options` value that is not a dict is logged as an error and ignored. The event is still sent.
+- The legacy properties still work. They fill the matching option only when it is unset, and the SDK always removes them from `properties`. Their values are no longer converted, so pass `True` or `False`, not `"true"`.
+
+  | Legacy property | Option |
+  | --- | --- |
+  | `$cookieless_mode` | `cookieless_mode` |
+  | `$ignore_sent_at` | `disable_skew_correction` |
+  | `$product_tour_id` | `product_tour_id` |
+  | `$process_person_profile` | `process_person_profile` |
+
+- An option set at any layer wins over its legacy property set at any layer. For example, `super_options={"cookieless_mode": True}` wins over an event's `$cookieless_mode: False`. When you move a default to options, move the per-event overrides of that key to options too.
+- A `None` option counts as unset, so a later step can fill it.
+
+Values apply in this order. Steps 2 to 4 fill only the options and properties that the steps before them left unset:
+
+1. the `options` and `properties` of the call
+2. context options and tags
+3. `super_options` and `super_properties`
+4. values the SDK sets: `$is_server` from `is_server`, `$geoip_disable` from `disable_geoip`, system properties such as `$os` and `$python_version`, `options.process_person_profile = false` for events without a distinct ID, and `$release_id` from `POSTHOG_RELEASE_ID`
+5. `before_send`, which sees the result of steps 1 to 4 and can change or remove any of it
+6. legacy properties, which fill unset options and are then removed
+
+A property set to `None` counts as set, so no later step fills it.
+`$set`, `$set_once`, `$groups` and `$group_set` fill one level deep.
+When the call and a later step both set one of them to a dict, the later step adds only the keys the call left out.
+For example, `super_properties={"$set": {"plan": "free", "source": "web"}}` and a call with `properties={"$set": {"plan": "pro"}}` send `{"plan": "pro", "source": "web"}`.
+
+These changes follow from this order:
+
+- Properties passed to a call now override `super_properties`. `super_properties` can no longer change `$lib` or `$lib_version`.
+- A `$is_server`, `$geoip_disable` or system property such as `$os` that you set in a call or a context tag now wins over the SDK's value. In 7.x the SDK overwrote it. `super_properties` win over the SDK's value too, so `super_properties={"$geoip_disable": False}` turns GeoIP lookup on for events, even with `disable_geoip=True`.
+- The `groups` argument merges into a `$groups` property of the call, and wins key by key. In 7.x it replaced the property. MCP events merge their identity's groups into a custom `$groups` property the same way.
+- A `$set`, `$set_once`, `$groups` or `$group_set` in `super_properties` no longer replaces the whole value of the call. The two merge, and the call wins key by key.
+- An event without a distinct ID gets `options.process_person_profile = false`. A `$process_person_profile: true` property no longer turns person processing back on. Set the option instead.
+- To change an option in `before_send`, edit `options`. A legacy property that `before_send` adds does not replace an option that is already set.
+- When the server enables minimal `$feature_flag_called` events, those events now keep `$window_id`, `$cookieless_mode`, `$ignore_sent_at` and `$product_tour_id`, so their options still apply.
+
+## AI capture
+
+- `capture_ai` and every built-in AI integration send to `/i/v1/ai/events`. The AI endpoint accepts events up to 8 MiB.
+- `enable_full_ai_capture` now controls only content: string truncation and media redaction. It no longer chooses the endpoint. `_use_ai_lane` and `_enable_multimodal_capture` still work as aliases.
+- The AI integrations call your client's `capture_ai`. A client object without `capture_ai` gets `capture` calls instead. A custom client must accept the `options` keyword argument.
+- Tests that pass a `Mock` client to an AI integration must assert on `mock.capture_ai`, not `mock.capture`.
+- When an AI integration or MCP falls back to a trace, run or session ID, it turns person processing off with a per-event option. This is the only option the integrations pass. It wins over `super_options`, context options and a `$process_person_profile: true` property. `before_send` can still change it.
+- The AI integrations have no `options` argument. To set options on their events, use `set_context_option`, `super_options`, or a legacy property such as `$cookieless_mode` in `posthog_properties`.
+- MCP's `PostHogCaptureEvent` has an `options` key.
+- New `Client` and `AsyncPosthog` arguments for the AI lane:
+  - `capture_ai_compression`: default none. `POSTHOG_CAPTURE_COMPRESSION` does not apply to it.
+  - `capture_ai_max_queue_size`: default 1000
+  - `capture_ai_timeout`: default 30 seconds
+  - `capture_ai_max_event_bytes`: default 8 MiB plus 64 KiB. You can only lower it.
+- The AI lane does not use `max_queue_size`, `timeout` or `capture_compression`. An invalid `capture_ai_*` value raises `ValueError` when you create the client.
+- The module-level client has no AI lane settings. To change them, create a `Client`.
+- `AsyncPosthog` has `capture_ai` and `capture_ai_immediate`.
+- `AsyncPosthog` sends events with `requests` in a worker thread. It uses `httpx` only for feature flags and remote config.
+- `AsyncPosthog` accepts `privacy_mode` and `enable_full_ai_capture`, with the same meaning as on `Client`. An AI integration given an `AsyncPosthog` client used to always truncate and redact media.
+
+## Batching and size limits
+
+- An analytics event over 900 KiB is dropped and logged. This now applies in `sync_mode` too.
+- An AI event over `capture_ai_max_event_bytes` is dropped and logged.
+- A batch stops before an event that would take it past 5 MiB. A larger event is sent alone.
+- `flush()` and `shutdown()` drain the analytics and AI queues at the same time.
+
+## OpenFeature provider
+
+`openfeature-provider-posthog` 0.2.0 works with posthog 7.x and 8.x.
+Older provider versions require posthog below 8.0, so upgrade the provider before or with posthog.
