Just fixed an i18n comment bug. Thanks to extra sweat I put in to make Daily highly configurable, no code update was necessary, just addition of a couple of jars plus config patch then restart. One of these days, I'll add hot-config for convenience. In practice, however, configuration changes without bringing systems down is rare. Even large banks use the good old shutdown-patch/reconfig-restart. Of course, they do load-balancing and rollout waves to minimize the inconvenience surface but I've never seen hot-config on their must-have list.
Anyway, do me a favor and post comments in your favorite foreign language to test the fix. Thanks.
