Changelog

Sourced from github.com/posthog/posthog-go's changelog.

1.13.1

Patch Changes

• 541b82f: Include group context in the $feature_flag_called LRU 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, device_id) was seen under.

1.13.0

Minor Changes

• dec8ade: Add opt-in panic capture for request context middleware.
• dec8ade: Add server-side request context helpers for net/http capture and exception events, plus EvaluateFlagsWithContext for using request-scoped distinct IDs during flag evaluation. Request-context flag evaluation does not generate personless IDs.

1.12.6

Patch Changes

• 9289d53: 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 surface an InconclusiveMatchError so the condition does not match.
