A new --no-routers cli option has been added to the cctrl command.

Using cctrl --no-routers will suppress the collection and display of connectors when issuing the ls command. This is especially useful when there are a lot of connectors installed and gathering the information from them could take a lot of time, causing unexpected timeouts.

Issues: CT-1437

A new affinity feature has been added in this release that will allow you to define a dedicated datasource for writes within a Composite Active/Active deployment.

This feature can be particularly useful to direct all writes for a specific user/application to a dedicated Write endpoint, where you need to remove any chance of writes in multiple clusters conflicting.

This feature can be enabled in a number of ways :- Via edits to the user.map file for Proxy configurations, via calls during connection, or via the --connector-affinity tpm option if using Bridge mode.

For more details on configuring this, and examples, consult the connector specific documentation here:

Support has now been added to allow monitoring via the New Relic Insights API, using a new script tungsten_newrelic_event

Issues: CT-892

If using mysqldump as your preferred choice of backup method, Stored Procedures and Functions would not be included in the generated dump file when using tungsten_provision_slave.

Issues: CT-1339

In a Composite Active/Active environment, the tungsten_post_process command now intelligently handles cross-site filter properties in the INI so that any defined filters are appended to the default values for any option that resolves to property replicator.stage.q-to-dbms.filters

Issues: CT-1372, CT-1449

Replaced md5 hashing to sha256 within tpm to fix issues where tpm install would fail on FIPS enabled environments.

Issues: CT-1451

When provisioning from a Primary node, in a Composite Active/Active environment, using tungsten_provision_slave, the replicator would fail to reset due to the incorrect service name being used.

Issues: CT-1458

Fixed an issue where, in Composite Active/Active environments, tpm would ignore the affinity passed with the tpm flag --connector-affinity.

Issues: CT-1465

If using tungsten_provision_slave to restore a previously failed Primary node, the provision could fail to recover the node.

Issues: CT-1468

A new mapcharset filter is included, which fixes collation incompatibilities when replicating from MySQL 8 to an older release (5.7 or 5.6)

This new filter should be enabled within any MySQL applier where the source is generated from a MySQL 8 database and the target is MySQL 5.7 or lower.

Issues: CT-1404

If SSL is enabled between replicators for THL Transfer, and a source node fails and becomes unresponsive, or is slow/overloaded, the replicator on the replica can fail to go offline due to a timeout, remaining in a GOING-ONLINE:SYNCHRONIZING state.

In a clustering envronment, this can prevent failovers occuring due to the manager waiting for the replicator which is stuck in a timeout loop.
