  Issue: CT-1518
• The tpm diag command now gathers the tungsten-manager/log/cctrl.log file.
  Issue: CT-1510
• The tpm diag command now gathers tungsten-manager/log/console.log* files.
  Issue: CT-1500

Connector (1)

• In a Composite Active/Active topology, connectors within both sites have read and write affinity set to the local site by default.
  Issues: CT-1502, CT-1505

Improvements, new features and functionality (3)

Command-line Tools (2)

• A new tpm option delete-service is now available to simplify the removal of clusters and/or replicator services.
  Issues: CT-210, CT-327, CT-1275
• A new utility, tungsten_skip_seqno has been added which allows events to be skipped based on filters, allowing the Tungsten Replicator to come back online with less manual intervention.
  Issues: CT-1511, CT-1453, CT-1087, CT-42

Connector (1)

• Full support for proxy-protocol v1 has been added to Tungsten Connector.

  Proxy protocol specifications can be found [here](http://www.haproxy.org/download/1.8/doc/proxy-protocol.txt)

  Enabling proxy-protocol:

  • You first need a compatible server, like MariaDB 10.3+ or Percona-5.6.25-73.0+, with the proxy protocol functionality enabled, for example in my.cnf: proxy-protocol-networks=*
  • Then install or update Tungsten with connector-enable-proxy-protocol=true

  You should now see the origin IP of the connecting application in place of the connector IP in show processlistand tungsten show processlist commands.

  Issue: CT-1533

Bug Fixes (7)

Command-line Tools (4)

• tpm now supports new MariaDB my_print_defaults flag --defaults-file
  Issue: CT-1528
• Fixed a tpm call to systemd services listing which was making tpm wrongly fall back to init.d. This issue was found when testing MariaDB 10.0.
  Issue: CT-1524
• Fixes an issue where the undeployallcommand would create a root owned wrapper.log in the ./tools directory.
  Issue: CT-1516
• This release includes a wide range of improvements and bug fixes for tpm and other command-line tools.
  Issue: CT-1509

Core Replicator (1)

• Fixes an issue where null values in JSON structures were incorrectly quoted once replicated. For example :

  [{"example":null}]

  would be replicated as

  [{"example":"null"}]

  Issue: CT-1523

Connector (1)

• Now properly supporting negative write affinity in Composite Active/Active clusters. For example you can now specifyaffinity=localSite,-remoteSite:localSite This allows access only to local sites for writes but still allows reads from remote sites if the local one goes down.
  Issue: CT-1507

Manager (1)

• Fixes an issue in Composite Active/Active environments that would occasionally cause the primary node to be set to read only.
  Issue: CT-1424
