+## Accumulo 1.5.1 Release Notes (Work in progress)
+
+
+### Notable Improvements
+
+Accumulo client code creates background threads that users can not stop.  This
+causes problems when using Accumulo with Tomcat or JBoss.  [ACCUMULO-2128][3]
+introduced the static utility org.apache.accumulo.core.util.CleanUp to clean
+these threads up.
+
+If IPv6 is enabled on nodes but not in use on the network, then Accumulo may
+have issues communicating with itself.  [ACCUMULO-2262][4] adds java
+configuration to startup scripts to prefer IPv4.
+
+[ACCUMULO-1933][7] allows lower case memory units in Accumulo configuration.
+
+[ACCUMULO-2360][14] allows users to configure the maximum frame size an
+Accumulo server will read.  This prevents non Accumulo client from connecting
+and causing memory exhaustion.
+
+The following documentation updates were made : [ACCUMULO-2127][17],
+[ACCUMULO-1956][18], and [ACCUMULO-1428][19].
+
+### Notable Bug Fixes
+
+ * [ACCUMULO-1800][5] fixed deletes made via the Proxy.
+ * [ACCUMULO-1994][6] fixed ranges in the Proxy.
+ * [ACCUMULO-2234][8] fixed offline map reduce over non default HDFS location
+ * [ACCUMULO-1615][15] fixed service accumulo-tserver stop
+ * [ACCUMULO-1876][16] fixed issues with ivy
+
+Some important internal bugs were fixed in Accumulo that should be considered
+when deciding to upgrade. These bugs are : [ACCUMULO-2057][9],
+[ACCUMULO-2261][10], [ACCUMULO-2037][11], [ACCUMULO-1821][12],
+[ACCUMULO-1572][13], [ACCUMULO-2078][20], [ACCUMULO-1985][21],
+[ACCUMULO-1999][22],[ACCUMULO-2065][23], and [ACCUMULO-1630][24]. 
+
+
+### Known Issues
+
+When using Accumulo 1.5 and Hadoop 2, Accumulo will call hsync() on hdfs.
+Calling hsync improves durability by ensuring data is on disk, however calling
+it frequently slows writes. A work around is to increase
+tserver.mutation.queue.max.  See [ACCUMULO-1905 comment][1], [ACCUMULO-1950][2], and
+the new tserver.mutation.queue.max documentation for more information.
