From 8a7d7ccb93c1c21067a6042164b8e1105aaf6830 Mon Sep 17 00:00:00 2001 From: Sean Du Date: Tue, 28 Apr 2026 11:44:33 +0800 Subject: [PATCH] Add support for server config override Add settings.override_server_config with enable flag and per-platform (Android/iOS) url + size fields. Use this config in /download/update to override the fixed 99_0_115.zip package source when needed.
