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

1.12.5

Patch Changes

• 6d243a6: Return ErrSDKDisabled from no-op clients when the project API key is missing, return ErrNoPersonalAPIKey before making requests for Personal API key dependent methods when no Personal API key is configured, and return ErrNoDistinctID from EvaluateFlags when distinct_id is missing.

New Features

• EvaluateFlags: New method on Client that returns a FeatureFlagEvaluations snapshot for a user using a single /flags request. The snapshot powers any number of IsEnabled / GetFlag / GetFlagPayload checks, fires deduped $feature_flag_called events with full v4 metadata (id, version, reason, request_id), and can be attached to a Capture event via the new Capture.Flags field to populate $feature/<key> and $active_feature_flags without another network call.
• Capture.Flags: New optional field on Capture that accepts a *FeatureFlagEvaluations snapshot. Takes precedence over SendFeatureFlags, avoids a hidden /flags request per event, and lets caller-supplied Properties override the auto-generated $feature/<key> values on conflict.

Internal

• Refactored the $feature_flag_called dedup logic into a shared helper so the existing single-flag path and the new snapshot path use identical semantics against the same per-distinct_id LRU cache.
• $feature_flag_called events from the snapshot path combine response-level errors (errors_while_computing_flags, quota_limited) with per-flag errors (flag_missing) comma-joined in $feature_flag_error, matching the granularity of the legacy single-flag path.

Greptile Summary

This PR bumps github.com/posthog/posthog-go from v1.12.1 to v1.12.5 in the backend module. The go.mod hash for the posthog-go module itself is unchanged across versions, confirming no new transitive dependencies are pulled in.

• v1.12.2–v1.12.4: Patch releases with bug fixes for no-op client behavior and mixed targeting in local flag evaluation.
• v1.12.5: Adds EvaluateFlags() (single-call flag snapshot), a new Capture.Flags field, and fixes for ErrSDKDisabled/ErrNoPersonalAPIKey/ErrNoDistinctID returns — all additive changes with no breaking API modifications.

Confidence Score: 5/5

Safe to merge — only go.mod and go.sum are touched, no application code changes.

The update is limited to bumping a single analytics/feature-flag SDK across four minor patch releases. All changes in the new versions are additive (new APIs, error sentinel values), and the unchanged go.mod hash for posthog-go confirms no new transitive dependencies are introduced. No application code is touched.

No files require special attention.

Important Files Changed

Filename	Overview
backend/go.mod	Bumps github.com/posthog/posthog-go from v1.12.1 to v1.12.5; no other dependency changes.
backend/go.sum	Updated checksums for posthog-go v1.12.5; the go.mod hash for posthog-go is unchanged, confirming no new transitive dependencies were introduced.
