Changelog

0.8.2 (2026-03-15)

Changed

Removed api_url from init() parameters — the proxy URL (https://api.mbuzz.co/api/v1) is now hardcoded. This prevents accidental bypass of the edge ingest proxy. For development, config.api_url can still be set directly after init.

Fixed

event() and conversion() now handle proxy-buffered responses gracefully — when the edge proxy accepts a request but Rails is temporarily unreachable, the SDK returns TrackResult(success=True) with nil IDs instead of TrackResult(success=False).

0.8.0 (2026-03-13)

Changed

Default API URL updated to https://api.mbuzz.co/api/v1 — traffic now routes through the edge ingest proxy for improved reliability.

0.7.4 (2026-02-17)

Fixed

identify() now writes user_id back to context — after a successful API call, user_id is stored in the RequestContext so that subsequent conversion() calls in the same request can resolve it.

0.7.3 (2026-02-03)

Added

Navigation-aware session creation — middleware now only creates server-side sessions for real page navigations, filtering out Turbo frames, htmx partials, fetch/XHR, prefetch, and other sub-requests. Uses browser-enforced Sec-Fetch-* headers as the primary signal with a framework-specific blacklist fallback for old browsers.
device_fingerprint() utility — computes SHA256(ip|user_agent)[0:32], matching the server-side fingerprint for session deduplication.
Async session creation via POST /sessions — fire-and-forget background thread on real navigations.

Fixed

5x visit count inflation caused by concurrent sub-requests (Turbo frames, htmx) each creating separate sessions on first page load.

0.7.0 (2026-01-15)

Initial release with Flask middleware, visitor cookie management, event tracking, user identification, and conversion tracking.
Session cookie removed — server handles session resolution via device fingerprint.
