+    v1.0.29: Raise seatableweb reverse-proxy upload limit to 200MB (`client_max_body_size 200m`) so attachment uploads larger than 1MB are not rejected with HTTP 413 after the official OpenResty proxy switch.
+
     Switch the reverse-proxy image from Bitnami OpenResty (`beclab/aboveos-bitnami-openresty:1.25.3-2`) to the official OpenResty image `openresty/openresty:1.29.2.5-bookworm-fat`.
 
     Align nginx config mounts and log paths with the official image layout (`/etc/nginx/conf.d/default.conf`, `/usr/local/openresty/nginx/logs/...`), and drop Bitnami-specific `OPENRESTY_CONF_FILE` wiring.
