Tarantool Cluster Manager 1.7

Release date: February 11, 2026

Latest release in series: 1.7.3

The TCM 1.7.x release includes a range of improvements and bug fixes aimed at enhancing the stability, usability, and configurability of the system. Key updates include a fix for the Metrics tab and export functionality, improvements to session management, better handling of audit log paths, enhanced visibility into migration status, and refinements to LDAP authentication.

A bug was fixed in 1.7.3 release that prevented the Metrics tab from displaying data and disabled the ability to export metrics.

In 1.7.2 the websession component has been updated to correctly handle user session creation. Users can now create the number of sessions specified in the configuration.

The auditlog component now has improved support in version 1.7.2 for absolute paths in its configuration. When a relative path is provided, the audit log file is now saved relative to the application's working directory.

In 1.7.1 the migration handling has been updated to improve visibility into the state of applied migrations. If a migration is reapplied, the system now logs a warning message in the logs.

A bug in the "test connection" functionality for Tarantool and etcd services has been fixed. Previously, the function did not correctly report the connection status for these services.

You can now control automatic creation of the default cluster using one of the following options:

• TCM_DEFAULT_CLUSTER environment variable
• default-cluster configuration parameter
• --default-cluster command-line flag

This allows administrators to explicitly enable or disable default cluster auto-creation depending on deployment requirements.

Error handling has been improved for LDAP authentication when the Automatically add non-existent users option is disabled.

It is also now possible to create a user via the UI with LDAP authentication enabled, simplifying user management in LDAP-based environments.
