 ### Minor Improvements
 
+* {% ghi 3180 %} Enable users to provide per-volume Hadoop Filesystem configuration
+  overrides via the Accumulo configuration. Hadoop Filesystem objects are configured
+  by the standard Hadoop mechanisms (default configuration, core-site.xml,
+  hdfs-site.xml, etc.), but these configuration files don't allow for the same
+  property to be specified with different values for different namespaces. This change
+  allows users to specify different property values for different Accumulo volumes, which
+  will be applied to the Hadoop Filesystem object created for each Accumulo volume.
+* {% ghi 3177 %} Added server side code to validate that property values conform to the
+  specified property type (string, boolean, etc.).
+* {% ghi 3175 %} Reset number of locks in SynchronousLoadingBlockCache from 2017 back
+  to 5003, the value that it was in 1.10. Also, modified the lock to be fair, which allows
+  the different scan threads in the server to make progress in a more fair manner when
+  they need to load a block into the cache.
+* {% ghi 3118 %} Added option to the `admin zoo-info-viewer` command to dump the ACLs
+  on ZooKeeper nodes. This information can be used to fix znodes with incorrect ACLs
