• New apps scaffolded with wheels new now ship a /up liveness/warm-up endpoint (app/controllers/Up.cfc + route). wheels deploy's proxy healthcheck already probes /up before traffic cutover, so the dispatch → controller → render path is compiled on a freshly deployed node before the first real visitor — moving the one-time cold-start compile (the bulk of first-request latency) off user traffic. The production-config guide documents the warm-up recipe and recommends setting the engine's template-inspection mode to never in production (#3210)
