PostHog Python

Minor changes

• 3aed638 Add a configurable $is_server event property (default true) so PostHog can identify server-side events. Set is_server=False when using posthog-python as a client/CLI so the device OS is attributed normally. — Thanks @turnipdabeets for your first contribution 🎉!

Patch changes

• 44e6b14 Fix async streaming responses from the AI wrappers (OpenAI, Anthropic, Gemini) so they support async with as well as async for. Previously, consuming a stream via async with (e.g. with pydantic-ai) raised TypeError: 'async_generator' object does not support the asynchronous context manager protocol. — Thanks @turnipdabeets for your first contribution 🎉!

Patch changes

• 643a810 Return empty flag defaults from Client flag helpers when the flags API fails. — Thanks @marandaneto!

Patch changes

• 034dce2 Make module-level setup no-op when API key is blank — Thanks @marandaneto!

Patch changes

• 8f6d6c8 Include group context in the $feature_flag_called dedupe key so group-scoped flags fire a separate event for each group a user is evaluated under, instead of being dedup-ed against the first group context the same (distinct_id, flag, response) was seen under. — Thanks @gustavohstrassburger!

Minor changes

• a44e0be Add async flag definition cache providers — Thanks @dustinbyrne!

Patch changes

• 0207088 Track OpenAI chat completions parse calls — Thanks @marandaneto!

Patch changes

• be9b78b Reject semver values with leading zeros in local flag evaluation. Per semver 2.0.0 §2, numeric identifiers must not include leading zeros — values like 1.07.3 are not valid semver and should not match targeting conditions. Both override values and flag values are now validated; invalid inputs raise InconclusiveMatchError so the condition does not match. — Thanks @dmarticus!

Patch changes

• 1574b1b Fix OpenAI usage parsing when token detail fields are null — Thanks @michael-ciridae!

Patch changes

• a098aa7 Fix Gemini web search extraction when response candidates are null. — Thanks @marandaneto!
