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!
