+## 5.2.0-19 (13-05-2026)
+- OpenVPN: simplify recursive routing fix — use a single blackhole route for the VPN server IP in table 1000 (no AWK, no ipcalc, no physical device detection required)
+
+- Minor bugs fixed
+
+## 5.2.0-2 (2026-05-10)
+- Fix startup loop on aarch64: drop s6-notifyoncheck wrapper so s6 supervises qbittorrent-nox directly (LSIO arm64 image has no notification-fd, causing EBADF restart loop)
 
 ## 5.2.0-1 (2026-05-10)
 - Fix qbittorrent-nox path (/usr/bin → /app) after LSIO image update
