-----------------
+Database cache memory increased
+--------------------------------
+
+As a result of growth of the UTXO set, performance with the prior default
+database cache of 100 MiB has suffered.
+For this reason the default was changed to 300 MiB in this release.
+
+For nodes on low-memory systems, the database cache can be changed back to
+100 MiB (or to another value) by either:
+
+- Adding `dbcache=100` in bitcoin.conf
+- Changing it in the GUI under `Options → Size of database cache`
+Note that the database cache setting has the most performance impact
+during initial sync of a node, and when catching up after downtime.
