Release of 2.8.3
+
+The 2.8.3 release is a minor update to spymemcached which
+includes a bug fix and some minor new features in support
+of Couchbase Server in the Couchbase Java Client project
+which depends on some protocol capabilities and handling
+in this project.
+
+Note that SPY-97 was opened for unlock, as the fix
+described above doesn't address situations where there
+is a TMPFAIL or a NOT_MY_VBUCKET, for example.
+
+Summary of changes by contributor:
+

Changes from release 2.8.1 to 2.8.2

+
contributors
Release of 2.8.2
+
+The 2.8.2 release is a minor update to spymemcached which
+includes bug fixes and a workaround to recently discovered
+issues.  The major workaround included in this release is
+that optimization has been disabled.  Recent tests
+indicate that there is a problem with optimization in the
+ascii implementation that may cause operations to come
+back with a cache miss prematurely.  Further, it was found
+on binary protocol that an error in the middle of binary
+optimization pipelined sets, it can cause lack of recovery
+on the client.
+
+To address these two correctness issues, optimization is
+now off by default, but may be enabled to make the client
+behave like it had previously.  It is expected that
+optimization will be re-enabled in the next release.
+
+There were also minor bugfixes for logging, some internal
+utilities, and handling of certain error cases.
+
+Summary of changes by contributor:
+
+Matt Ingenthron (11):
+      Change vbucket retry logging to debug level. SPY-87
+      Make queueReconnect protected so subclasses can request reconnects.
+      Make the OperationState volatile.  SPY-88
+      Add javadoc for OperationFuture.
+      Comment correction in MemcachedConnection.  Non-javadoc.
+      Let offline try to work with already downloaded mvn.
+      Correct test for StringUtils.join().
+      Disable optimization by default, remove assert. SPY-88.
+      Revert ErrorCode and OperationStatus changes.
+      Change selection key logging to debug level.
+      Fixed misc checkstyle errors which crept in.
+
+Mike Wiederhold (9):
+      Retry not my vbucket error for optimized sets. SPY-88
+      Fixed tap message test cases
+      Create an ErrorCode class for error codes
+      OperationStatus now has an error code
+      Check if op is null before asserting in OperationFuture
+      SPY-90: getStats() can return an error
+      Fixed parsing of delete tap packet
+      JCBC-52: Fix StringUtils.join()
+      JCBC-72: Make OperationException extendable
+
+Marty Schoch (2):
+      add TAP Opcodes for start/end checkpoint
+      add support for TAP request/response with checkpoint info

Release of 2.8.1
+
+The 2.8.1 release is a minor update to spymemcached which
+includes bug fixes related to the TAP feature and some
+minor changes to generate better maven descriptions.
+
+Summary of changes by contributor:
+
+Matt Ingenthron (10):
+      Enhanced TapTest, ensuring success with random leftovers.
+      Remove test for "stats cachedump".
+      Wait longer on tap data received.
+      Fixed handling of TAP flags.
+      Decode TAP mutation flags as host byte order.
+      Add test coverage for ResponseMessage and fix to get bytes.
+      Complete the removal of stats cachedump.
+      Bump log4j to 1.2.16 to get rid of transitive JMS deps.
+      Make log4j, spring-beans optional in our maven artifacts.
+      Added toString() for ResponseMessage.
+
+Mike Wiederhold (2):
+      Created TapStream abstraction
+      Made TapAck its own class
+
+Raghavan Srinivas (1):

Changes from release 2.7.3 to 2.8.0

+
contributors
Release of 2.8.0
+
+The 2.8.0 release is a minor update to spymemcached which
+includes bug fixes, some minor new features and some
+features split out into a separate project.
+
+Starting in the 2.8.0 release, there is no longer support
+directly in the MemcachedClient object for Membase Server.
+That has been broken out into a separate library which is
+hosted at http://www.couchbase.com/develop/java/current
+
+By separating out that code, it reduced the dependency
+burden on this project.  Also, a number of the proposed
+new features, namely support for Couchbase Server views
+seemed increasingly like they did not belong in this
+project.
+
+The new project should be compatible with minimal,
+though some, code changes.  It is Open Source under an
+Apache 2.0 license, and support of that library continues
+by the same developers.
+
+This new release also includes Iterator versions of
+getAsyncBulk and getBulk.
+
+For example:
+
+    public PrefixAdderIterator implements Iterator {
+
+      private final String prefix;
+      private final Iterator iterator;
+      public PrefixAdderIterator(String prefix,
+             Iterator iterator) {
+        this.prefix = prefix;
+        this.iterator = iterator;
+      }
+      ...
+      public String next() {
+        return prefix+iterator.next();
+      }
+     ...
+    }
+
+    rather than
+
+     List prefixedKeys = new ArrayList();
+     for (String key: keys) {
+      prefixedKeys.add(prefix+key);
+     }
+
+Thanks much to Ted Crossman for the idea and
+contribution.

+The major change, and the reason for the version bump, is that timeout
+handling has been improved.  Previously, timed out operations may have
+actually been written to the network even after they'd timed out.  The
+change required some small API changes (generally forward compatible
+so minor version bump only) and adds a new operation state of timedout.
+
+Other changes include performance enhancements, transcoder enahncements
+and improvements in the continuious timeout counter to be per
+connection rather than for the entire MemcachedClient.  The library is
+now easier to use in Spring as well, owing to a FactoryBean contribution.
+
+Between rc1 and rc2, a major issue (issue 175) with the
+KetamaNodeLocator was found, so some changes were backported along with
+the fix.

Changes from release 2.4.2 to 2.4rc1

+
contributors
Prerelease of 2.4
+
+Changes since the 2.3 series.
+
+Bug Fixes:
+
+* Memcached node tracking.
+  When a timeout occurs on an operation, the exception indicates the
+  server node that was the intendend recipient of the operation.
+* Fixed reconnect loss on multiple simultaneous connection failures.
+  This is a rare occurrence, but the wrong thing would happen if two
+  simultaneous reconnects were requeued for any reason.
+* Fixed a race condition that occurred when tearing down a connection.
+  There was a case where shutting down a connection would cause an NPE
+  to get logged due to the a race between a selector check and the
+  selector being shut down.  Unlikely to affect a running app, but
+  it was still wrong.
+* Handle initial connect failures.
+  There were rare cases where an async connect would error instantly
+  on the first attempt, but that connect wouldn't be retried.
+
+Features:
+
+* ConnectionFactoryBuilder
+  Rather than having to build a custom subclass of
+  DefaultConnectionFactory to override behaviors, you can now use a
+  ConnectionFactoryBuilder to easily assemble a ConnectionFactory as
+  you want it.
+* Mutation-only CAS mutator
+  Previously, the CASMutator required an initial object to use if the
+  object you were attempting to mutate wasn't found.  Now you can
+  specify this as NULL and CASMutator will *only* mutate an existing
+  object, but never create a new one.
+* CacheLoader
+  CacheLoader provides a couple of convenient mechanisms for
+  efficiently loading bulk data.  I've seen many benchmarks trying to
+  see how fast data can go into memcached through the client (as
+  opposed to normal usage), but they do things to make it
+  unnecessarily slow.  This should satisfy both benchmarking
+  requirements and legitimate bulk loading requirements.
+
+Performance Enhancements:
+
+* Disable Nagle Algorithm by Default
+  The usage of the Nagle algorithm (tcpNoDelay) is now configurable
+  and is configured off by default (Nagle algorithm off = tcpNoDelay
+  on).  This should be more optimal for most configurations.
+* Multi-set Escalation in the Binary Protocol
+  With no changes to the API, multiple sequential sets will be
+  escalated into a multi-set operation similar to multi-get.  In a
+  bulk load test, this is generally around 2x faster.
+* Asynchronous Transcoding Service
+  A transcoder can request a transcoder service (effectively a
+  threadpool) to asynchronously decode cache response objects both
+  outside of the API and outside of the caller thread.

+
+* A Map interface to memcached
+    This is somewhat limited, of course, in that you obviously can't
+    list all of the mappings, but you can replace many Map
+    usages with a memcached backed map.
+
+* Failure Modes
+    There are now three failure modes to choose from so you can decide
+    what you want to do in the case of a node failure. (see
+    FailureMode in the documentation for more details).
+
+* Connection Observation
+    You can register for callbacks that will notify you when a node
+    goes up or down.  This is useful for things like notifying
+    monitoring systems, or preventing a system from starting up until
+    a required minimum number of memcached servers come online.
+
+* Misc bug fixes and accessibility to memcached functionality.

2.1rc3 includes a couple bug fixes and a convenience feature:
+
+1) The three internal queues can be sized individually.
+2) Fixed an elusive NPE in a partial read in bin.
+3) Brought in Nelz' consistent hash convenience factory.
+
+Regarding #1, it's pretty easy to overflow a read queue by having a
+giant write queue such that the write queue's short commands going out
+can get drained fairly quickly and set up for read, but there's no
+room for the reads.  With new connection factory methods, it's both
+easy to simulate that as well as size appropriately for your
+application in such a way that might avoid it.  The defaults should
+probably be fine for everyone, of course.
+
+The effect of #2 was mostly that one of my tests occasionally failed.
+It was a real bug though and would've sucked for someone someday.
+
+The KetamaConnectionFactory can be used place of
+DefaultConnectionFactory to get a stock ketama setup.  I don't
+particularly like the KETAMA_HASH (md5), but the goal is to have a few
+configurations on the shelf that one can choose from.
