+# Apache Accumulo 1.6.5 Release Notes (DRAFT)
+Apache Accumulo 1.6.5 is a maintenance release on the 1.6 version branch. This
+release contains changes from 55 issues, comprised of bug-fixes, performance
+improvements, build quality improvements, and more. See [JIRA][JIRA_165] for a
+complete list.
+Users of any previous 1.6.x release are strongly encouraged to update as soon as
+possible to benefit from the improvements with very little concern in change of
+underlying functionality. Users of 1.4 or 1.5 that are seeking to upgrade to 1.6
+should consider 1.6.5 as a starting point.
+## Highlights
+### Queued Compactions Not Running
+Found and fixed a bug ([ACCUMULO-4016][ACCUMULO-4016]) in which some queued
+compactions would never run if the number of files changed while the tablet was
+### Faster Processing of Conditional Mutations
+Improved ConditionalMutation processing time by a factor of 3.
+### Slow GC While Bulk Importing
+Found and worked around an issue where lots of bulk imports creating many new
+files would significantly impair the Accumulo GC service, and possibly prevent
+it from running to completion entirely. ([ACCUMULO-4021][ACCUMULO-4021])
+### Improvements in Locating Client Configuration File
+Fixed some unexpected error messages related to setting
+ACCUMULO_CLIENT_CONF_PATH, and improved the detection of the client.conf file if
+ACCUMULO_CLIENT_CONF_PATH was set to a directory containing client.conf.
+## Other Notable Changes
+ * [ACCUMULO-3509][ACCUMULO-3509] Fixed some lock contention in TabletServer, preventing
resource cleanup
+ * [ACCUMULO-3734][ACCUMULO-3734] Fixed quote-escaping bug in VisibilityConstraint
+ * [ACCUMULO-4025][ACCUMULO-4025] Fixed cleanup of bulk load fate transactions
+ * [ACCUMULO-4065][ACCUMULO-4065] Worked around buggy thrift behavior with oneway methods
+ * [ACCUMULO-4070][ACCUMULO-4070] Fixed Kerberos renewal
+ * [ACCUMULO-4098][ACCUMULO-4098],[ACCUMULO-4113][ACCUMULO-4113] Fixed widespread misuse

+## Testing
+Each unit and functional test only runs on a single node, while the RandomWalk
+and Continuous Ingest tests run on any number of nodes. *Agitation* refers to
+randomly restarting Accumulo processes and Hadoop Datanode processes, and, in
+HDFS High-Availability instances, forcing NameNode failover.
