-## 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)
-
+## 5.2.0-8 (12-05-2026)
 - Minor bugs fixed
+## 5.2.0-7 (12-05-2026)
+- Minor bugs fixed
+## 5.2.0-6 (12-05-2026)
+- Minor bugs fixed
+
+## 5.2.0-3 (2026-05-12)
+- Fix WireGuard "RTNETLINK answers: File exists" crash loop: clean up stale interface and routing rules before re-establishing the tunnel on S6 service restart
 
 ## 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)
