Changelog

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

1.19.0

Minor Changes

• 154fd08: Add a $feature_flag_has_experiment boolean property to $feature_flag_called events. The value comes from the has_experiment field the server reports on flag metadata (/flags?v=2) and on local-evaluation flag definitions. The property is only sent when the server explicitly reported has_experiment (true or false); it is omitted when unknown (older deployments, v3 responses, or flags missing from the response).

1.18.0

Minor Changes

• 39c72dc: Drop the newest event instead of blocking when the in-memory queue is full, and make the queue size configurable.

  • Enqueue now returns ErrQueueFull when the queue is full, dropping the newest message rather than blocking the caller until space frees up. This matches posthog-python and posthog-rs. The drop is reported only through the returned error, not through Callback.Failure, so it stays cheap and off the callback goroutines under sustained overload. Backfill/bulk callers: check the error returned by Enqueue for ErrQueueFull and throttle or retry (or raise MaxQueueSize); otherwise events that overflow the queue are dropped, not delayed.
  • Add Config.MaxQueueSize (default DefaultMaxQueueSize = 10000) to control the in-memory message queue capacity independently of BatchSize. It is clamped up to BatchSize so the queue always holds at least one full batch. This replaces the previous hardcoded BatchSize * 10 sizing.
  • Change the default BatchSize (DefaultBatchSize) from 250 to 100, aligning with posthog-python, posthog-node, and posthog-rs. Callers that set BatchSize explicitly are unaffected.

1.17.5

Patch Changes

• fe66557: Change the default capture delivery budget from 10 attempts to 4 (DefaultMaxAttempts) when Config.MaxRetries is unset, aligning with the cross-SDK Capture V1 parity standard (posthog-rs uses the same envelope). This affects both the v0 (/batch/) and v1 send paths, since they share the attempt budget. Callers that set MaxRetries explicitly are unaffected.
• 3d8404a: Unify the capture retry backoff ceiling at 30s. DefaultBackoff's cap changes from 10s to 30s (default only — override via Config.RetryAfter), and the Capture V1 send now clamps a server Retry-After to the same 30s so a hostile or buggy header cannot park a batch goroutine. Retry-After still acts as a minimum; the configured backoff is never truncated. This aligns the default retry behavior with posthog-rs and posthog-python.

1.17.4

Patch Changes

• 25e43f8: Stop duplicating distinct_id inside /flags person properties.

1.17.3

Patch Changes

• dafed74: Retry remote feature flag requests after transient 502 and 504 responses.

1.17.2

Patch Changes

• d98ef79: Retry feature flag requests after transient network errors only. The feature flag request retry count defaults to 1 and can be set to 0 to disable retries.

1.17.1

Patch Changes

• 651b303: Preserve caller-provided system context values when building capture v1 event properties.
• e0eb8bd: Send capture batches uncompressed when request-body compression fails instead of failing the batch.
• 71f5c2e: Expose capture default properties to BeforeSend hooks before serialization.

1.17.0
