+* Sun Aug 02 2026 Zoran Pericic <zpericic@netst.org> - 2.11.5-2
+- Set STORAGE_PATH_USE_TMP_FOLDER=false in config.env and quadlet:
+  upstream joins STORAGE_PATH onto os.tmpdir() by default (even for
+  absolute paths), so artifacts were written to ephemeral /tmp instead
+  of /var/cache/turborepo-remote-cache and lost on restart
+- Add :U to the quadlet volume so the host cache dir is chowned to the
+  container's app user
+
 * Sun Aug 02 2026 Zoran Pericic <zpericic@netst.org> - 2.11.5-1
 - Update to 2.11.5
 - Adds local cache cleanup endpoint (2.9.0) and read-only mode (2.10.0)
