  +UTXO memory accounting
  +----------------------
  +
  +Memory usage for the UTXO cache is being calculated more accurately, so that
  +the configured limit (`-dbcache`) will be respected when memory usage peaks
  +during cache flushes. The memory accounting in prior releases is estimated to
  +only account for half the actual peak utilization.
  +
  +The default `-dbcache` has also been changed in this release to 450MiB. Users
  +who currently set `-dbcache` to a high value (e.g. to keep the UTXO more fully
  +cached in memory) should consider increasing this setting in order to achieve
  +the same cache performance as prior releases. Users on low-memory systems
  +(such as systems with 1GB or less) should consider specifying a lower value for
  +this parameter.
  +
  +Additional information relating to running on low-memory systems can be found
