+### New accounts cache
+
+Introduction of a brand-new AccountCache decomposed into smaller chunks that can be
+cached individually:
+
+- External IDs + user name (cached in ExternalIdCache)
+- CachedAccountDetails (newly cached)
+- Gerrit’s default settings CachedAccountDetails – a new class representing all
+ information stored under the user’s ref (`refs/users/<sharded-id>`)
+
+The new structure is cleverly designed to require a lot less I/O when an entry needs to be
+reloaded and lowering the ratio of cache-miss in case of user’s details updates.
+
### Support for Java 11
Gerrit is now officially supported on Java 11, in addition to Java 8.
