Feature flags got a dedicated testing tab to evaluate flags against specific users with full condition breakdowns. Event ingestion filtering lets you drop unwanted events before they hit your data using boolean expression rules with dry-run and live modes. Experiments added winsorization support for ratio metrics to reduce outlier effects, plus Linux support landed for PostHog Code (x64 and arm64). The JVM server SDK gained request-scoped context to automatically link backend events to frontend sessions.
