 - The built-in system memory metrics now include additional states such as
   Cached and Buffered.
-- The `metrics.statsd_server` has had a new option, `legacy_gauge_aggregation`, 
-  added that averages Gauge metric readings rather than simply storing the 
-  most recent value. This is meant to allow for a smooth migration from
-  `collectd`'s StatsD server to `memfaultd`'s. New integrations should

 ### Changed
 
 - The default on-device rate limit for logs ingested by `memfaultd` has been
   increased from 500 lines per minute to 1000 lines per minute
 
-### Fixed 
-- Arbitrary ASCII strings between 1 and 128 in length can 
-  now be used in StatsD metric keys (besides the `:` delimiter),
-  matching the behavior described in the docs.
