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 +here: +[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7). 0.14.1 Change log ================= |
