Version End of Life. 30 May 2021
Release 6.0.1 is a bugfix release.
The following changes have been made to Continuent Replicator and may affect existing scripts and integration tools. Any scripts or environment which make use of these tools should check and update for the new configuration:
The tpm diag command has been improved to include more information about the environment, including:
The output from the lsof command.
The output from the ps command.
The output from the show full processlist command within mysql.
Copies of all the
Copies of all the
including directory configurations.
Improvements to the clarity of some commands.
The INI files used by tpm (if using INI installs) are included.

The trepctl services has been updated to
support the auto-refresh option using the
The trepctl has been updated with a new command, servicetable command. This outputs the status information for multiple services in a tabular format to make it easier to identify the state for multi-service replicators. For example:
trepctl servicetableProcessing servicetable command... Service | Status | Role | MasterConnectUri | SeqNo | Latency -------------------- | ------------------------------ | ---------- | ------------------------------ | ---------- | ---------- alpha | ONLINE | slave | thl://trfiltera:2112/ | 322 | 0.00 beta | ONLINE | slave | thl://ubuntuheterosrc:2112/ | 12 | 4658.59 Finished servicetable command...
The command also supports the auto-refresh option,
This change is not backwards compatible; when upgrading, you should upgrade slaves first and then the master to ensure compatibility. Once you have extracted data with the GEOMETRY type into THL, the THL will no longer be compatible with any version of the replicator that does not support the GEOMETRY datatype.
When using Net::SSH within tpm, more detailed information about any specific failures or errors is now provided.
tpm would mistakenly report issues with JSON columns during installation which no longer applies as JSON support for MySQL 5.7 was added in 6.0.0.

pkeyhad not been enabled.
The trepctl status would fail badly if the service name did not exist in the configuration, or if multipl services were configured.
Issues: CT-545, CT-593
When using tpm with the INI method, the command would search multiple locations for suitable INI files. This could lead to multiple definitions of the same service, which could in turn lead to duplication of the installation process and occasional failures. If multiple INI files are found, a warning is now produced to highlight the potential for failures.
