+### Fixed
+- Multi-target load balancing (added in 1.2.0) crashed every request to a load-balanced host: `ops/nginx_conf/targetinfo.lua` required a nonexistent `resty.balancer.round_robin` module. The `lua-resty-balancer` rock installed by the Dockerfile/`install.sh` doesn't provide that path — it provides `resty.roundrobin` (constructed as `roundrobin:new(nodes)`, not `:new()` + `:reinit(nodes)`). Fixed `targetinfo.lua` to use the real module and API; verified end-to-end that requests now round-robin across targets with no Lua errors.
