anchor.diff:  == Fixed Issues
   
   * HybridTime timestamp propagation now works in the Java client when using scan
  -  tokens. (link:https://issues.apache.org/jira/browse/KUDU-1411[KUDU-1411])
  +  tokens (see link:https://issues.apache.org/jira/browse/KUDU-1411[KUDU-1411]).
   
   * Fixed an error message commonly found in tablet server logs indicating that
  -  operations were being read "from the future".
  -  (link:https://issues.apache.org/jira/browse/KUDU-1078[KUDU-1078])
  -
  -* Tombstoned tablets no longer report metrics.
  -  (link:https://issues.apache.org/jira/browse/KUDU-2044[KUDU-2044])
  +  operations were being read "from the future"
  +  (see link:https://issues.apache.org/jira/browse/KUDU-1078[KUDU-1078]).
  +
  +* Tombstoned tablets no longer report metrics
  +  (see link:https://issues.apache.org/jira/browse/KUDU-2044[KUDU-2044]).
   
   * Fixed a bug in the C++ client which could cause tablets to be erroneously
     pruned, or skipped, during certain scans, resulting in fewer results than
     expected being returned from queries. The bug only affected tables whose range
  -  partition columns are a proper prefix of the primary key.
  -  (link:https://issues.apache.org/jira/browse/KUDU-2173[KUDU-2173])
  +  partition columns are a proper prefix of the primary key
  +  (see link:https://issues.apache.org/jira/browse/KUDU-2173[KUDU-2173]).
   
   * Published Kudu Java artifacts are now fully compatible with JRE 7 and JRE 8.
     There was previously a bug in the release process which made them compatible
  -  only with JRE 8.
  -  (link:https://issues.apache.org/jira/browse/KUDU-2188[KUDU-2188])
  +  only with JRE 8
  +  (see link:https://issues.apache.org/jira/browse/KUDU-2188[KUDU-2188]).
   
   * Fixed a typo in the list of default TLS ciphers used by Kudu servers. As a
     result, two additional cipher suites are now available:
  
positive.code: [[rn_1.6.0_upgrade_notes]]
  == Upgrade Notes
  
  * TBD
  
  [[rn_1.6.0_deprecations]]
  == Deprecations
  
  * Support for Java 7 has been deprecated since Kudu 1.5.0 and may be removed in
    the next major release.
  
  * Support for Spark 1 (kudu-spark_2.10) has been deprecated since Kudu 1.6.0
    (TBD: no longer supported?)
  
  [[rn_1.6.0_new_features]]
  == New features
  
negative.code:   settings: `--webserver_tls_ciphers` and `--webserver_tls_min_protocol`.
    These flags allow the advertised TLS ciphers and TLS protocol versions to be
    configured. Additionally, the webserver now excludes insecure legacy ciphers
    by default
    (see link:https://issues.apache.org/jira/browse/KUDU-2190[KUDU-2190]).
  
  == Optimizations and improvements
  
  * Kudu servers can now tolerate short interruptions in NTP clock
    synchronization. NTP synchronization is still required when any Kudu daemon
    starts up. If NTP synchronization is not available, diagnostic information
    is now logged to help pinpoint the issue
    (see link:https://issues.apache.org/jira/browse/KUDU-1578[KUDU-1578]).
  
  * Tablet server startup time has been improved significantly on servers
    containing large numbers of blocks.
