# AOC v1.7.17 Release Notes
**Release Date:** 2026-05-29
## Security & Hardening
### Alpine.js CSP Build
The frontend now loads the **Alpine.js CSP build** (`@alpinejs/csp@3.15.12`) instead of the standard distribution. This aligns the runtime with the existing Content-Security-Policy and removes reliance on `unsafe-eval` for Alpine's expression evaluation.
- **File:** `backend/frontend/index.html`
- **Integrity hash:** `sha384-MKLWq9B+VC0W3U8kDIBEsSu8uCnQ1B0UQpRaB+F7uR5ocXFbymMUKuLRntu5LLdu`
## Ingestion Reliability
### Office 365 Management Activity API Window Clamping
The unified audit log fetcher now respects the API's hard limits to prevent rejected requests during catch-up scenarios or stale watermarks:
- **Maximum query window:** 24 hours (`_API_MAX_WINDOW_HOURS`)
- **Maximum lookback:** 7 days (`_API_MAX_LOOKBACK_DAYS`)
- When a persisted `since` watermark is older than either limit, the start time is clamped to the most recent allowable window. Subsequent fetches continue catching up normally.
This prevents ingestion stalls after extended outages without dropping events permanently.
