• Added graph functionality using the OCGraph class. For details, see OCGraph Java Library.

​

3.7.0 (2025-11-21)

3.6.4 (2025-09-10)

• Added the printUuid setting to the .ocient-cli-configuration file that determines whether the CLI automatically prints the Universally Unique IDentifier (UUID) of the query after the submission of the query by the user. The values are on and off. If you do not specify this setting, the default value is off.
• Re-enabled asynchronous updates. Now, the system executes updates asynchronously by default.

• Disabled asynchronous updates.

​

3.5.0 (2025-06-07)

  • Added periodic polling of the .ocient-cli-configuration file, so the system applies changes to the settings in the file at runtime. The default interval is 5 minutes. You can change the default value by setting the com.ocient.cli.config-poll-interval system property to the chosen number of seconds.
  • Fixed the CLI result set output from formatted to a raw string.
