24   -Although it was recommended to leave the interval at 1000ms (1 second) as graphite seems to dampen missing data points on intervals larger than that, the newer version of this application allows more precise or longer delays given the use of guauges instead of increments.

27 23
28 24 Scheduler wall time statistics are now disabled by default to keep in line with 0.1.0 behaviour, and after some bugs being reported when the Erlang scheduler would lock on such calls in R15B01 a few times in a day, never to unlock again. People who want to take the risk of running these statistics can do it by setting the `vmstats` env variable `sched_time` to `true`.

32   -You are likely using vmstats with an Erlang release prior to R15B. Switch away from master and use the tag "0.1.0" to get back to the functionning version you knew.
  28 +That's because you should use tags for stable versions instead! The changelog below should let you know what to expect.
