 ## bunyan 0.5.0 (not yet released)
 
+- Use 10/20/... instead of 1/2/... for level constant values. Ostensibly this
+  allows for intermediary levels from the defined "trace/debug/..." set.
+  However, that is discouraged. I'd need a strong user argument to add
+  support for easily using alternative levels. Consider using a separate
+  JSON field instead.
 - s/service/name/ for Logger name field. "service" is unnecessarily tied
   to usage for a service. No need to differ from log4j Logger "name".
 - Add `log.level(...)` and `log.levels(...)` API for changing logger stream

 # Levels
 
-- "fatal" (6): the service/app is going to stop or become unusable now
-- "error" (5): fatal for a particular request, but the service/app continues servicing other requests
-- "warn" (4): a note on something that should probably be looked at by an operator
-- "info" (3): detail on regular operation
-- "debug" (2): anything else, i.e. too verbose to be included in "info" level.
-- "trace" (1): logging from external libraries used by your app
+- "fatal" (60): the service/app is going to stop or become unusable now

 "debug" should be used sparingly. Information that will be useful to debug
 errors *post mortem* should usually be included in "info" messages if it's
