== 0.4.0 / 2007-09-10

* Major Enhancements
  * Add the ability for conditions to override transition state (for exceptional cases)
  * Implement dynamic load of config files while god is running (god load <filename>)
  * Add ability to save auto-daemonized process output to a log file
  * Add robust default stop lambda command for auto-daemonized processes (inspired by _eric)
  * Add status command for god binary (shows status of each watch)

  * Add log command to god binary to get real time logs for a specific watch from a running god instance
  * Add terminate command for god binary (stop god and all watches)
* Minor Enhancements
  * Enforce validity of Watches
