mod_conversejs: This one weird trick updates options on reload Options queried from the config in get_converse_options() would take effect immediately after Prosody reloads the config. Including 'conversejs_options' in this behaviour by simply moving a line seems worth it.

This module writes out a traceback to `traceback.txt` in Prosodys data
directory (see `prosodyctl about`) when the signal `SIGUSR1` is
received. This is useful when debugging seemingly frozen instances in
case it is stuck in Lua code.
