What We Are Particularly Excited About
In this release we are particularly excited about these new Slips features:
- Add the HTTPS anomaly detection module with adaptive baselines, confidence scoring, and detailed evidence reasons.
- Enable ADWIN drift detection by default for HTTPS anomaly detection, with separate hourly and flow drift paths.
- Add a local HTML report generator for HTTPS anomaly detection logs, with interactive charts and anomaly summaries.
- Improve performance under high-throughput traffic and reduce OOM risk.
- Improve Redis memory hygiene with tighter TTLs, capped zsets, and periodic cleanups.
- Improve the speed of the HTTP Analyzer module.
