+
+Tarantool Cluster Manager 1.3
+=============================
+
+Release date: March 14, 2025
+
+Latest release in series: 1.3.1
+
+|tcm_full_name| 1.3.0 enhances the TCF integration page with minor bug fixes and functional improvements.
+Below is an overview of key updates.
+
+.. _tcm_releases_1_3_0_tcf:
+
+TCF page improvements
+------------------------
+
+Starting from version 1.3.0, |tcm| provides additional actions for managing TCF clusters through the web interface.
+You can now use **promote** and **demote** operations directly on the **TCF** page without switching to external tools.
+Also, the **TCF** page is now disabled by default and must be explicitly enabled if needed.
+In addition, |tcm| now supports connections to multiple gRPC servers, which improves integration with distributed cluster infrastructures.
+
+
+.. _tcm_releases_1_3_0_explorer:
+Explorer improvements
+------------------------
+
+|tcm| 1.3.0 introduces a new approach to pagination in the Explorer. Instead of using a tuple, the interface now relies on pointers for navigating result pages.
+When sending data to the frontend, binary values (varbinary) are now automatically encoded in base64.
+
+Additionally, |tcm| fixes an issue where queries using a datetime key could result in type mismatch errors due to incorrect index part handling.
+
+
+.. _tcm_releases_1_3_0_etcd:
+etcd integration fixes
+------------------------
+
+In this version, |tcm| improves its interaction with etcd-based data sources.
+Tabs that use etcd for updating can now be refreshed even if some of the etcd endpoints are temporarily unavailable.
+To improve stability, a check was added to detect and correctly handle empty tuple arrays, preventing unexpected errors when processing empty data.
+
+
+.. _tcm_releases_1_3_0_crud:
+CRUD and query parsing
+------------------------
+
+|tcm| 1.3.0 includes improvements to how search expressions are parsed in `CRUD <https://github.com/tarantool/crud>`__ explorer queries. The CRUD explorer is located on the **Tuples** page.
+This release also introduces dedicated tests for the relevant components to ensure consistent behavior in future versions.
+
+
+Since version 1.3.1, |tcm| includes missing changes that have now been properly delivered.
+In addition, several minor issues flagged by the Svacer linter were fixed to improve overall code quality and maintainability.

+.. _tcm_releases_1_4:
+
+Tarantool Cluster Manager 1.4
+=============================
+
+Release date: June 9, 2025
+
+Latest release in series: 1.4.0
+
+|tcm_full_name| 1.4.0 improves LDAP support and includes several enhancements and fixes aimed at improving authentication flexibility and system stability.
+
+.. _tcm_releases_1_4_0_ldap:
+
+LDAP support improvements
+------------------------
+
+|tcm| 1.4.0 significantly enhances the experience of working with LDAP authentication.
+The web interface now includes a visual confirmation pop-up when a connection to an LDAP server is successfully established.
+This helps administrators quickly verify the correctness of LDAP settings without checking logs or reloading the page.
+
+The authentication settings now support switching between local and LDAP methods directly in the interface, making it easier to configure hybrid or alternative access scenarios.
+
+The LDAP configuration form has been simplified:
+
+* The ``groupQueryTemplate`` field is now optional, allowing LDAP authentication without querying for user groups.
+* The ``queryUser`` and ``queryPassword`` fields are also optional, which enables anonymous binding to the LDAP server.
+* You now only need to provide either ``templateDN`` or ``templateQuery``, instead of both -- reducing configuration complexity.
+

+
+
+.. _tcm_releases_1_4_0_infra_fixes:
+
+LDAP support improvements
+------------------------
+
+In version 1.4.0, |tcm| improves the behavior of the etcd client.
+Previously, if one of the etcd nodes became unresponsive while keeping its port open, the client could hang indefinitely.
+This issue has been fixed to ensure better resilience of etcd-based components.
+
+Additionally, the audit log mechanism now correctly creates log files in the directory of the running application binary.
+To learn more, see :ref:`tcm_audit_log_config`.

+
+Tarantool Cluster Manager 1.5
+=============================
+
+Release date: August 28, 2025
+
+Latest release in series: 1.5.1
+
+|tcm_full_name| 1.5.0 introduces a new UI page for configuring TCF clusters and includes important fixes that enhance reliability, compliance, and user experience.
+
+
+.. _tcm_releases_1_5_0_tcf_config:
+
+TCF cluster configuration in UI
+-------------------------------
+
+|tcm| 1.5.0 adds a dedicated settings page for managing TCF cluster parameters directly through the web interface.
+You can now retrieve and modify key fields that define cluster behavior and failover logic without editing configuration files manually.
+
+The new page allows configuring the following parameters:
+
+- ``dml_users`` -- a list of users with DML access
+- ``cluster1``, ``cluster2`` -- settings for connected clusters
+- ``replication_user``, ``replication_password`` -- replication credentials
+- ``failover_timeout`` -- delay before switching to a failover node
+- ``initial_status`` -- default service state on startup
+- ``max_suspect_counts`` -- the threshold for marking a node as failed
+- ``health_check_delay`` -- interval between health checks
+- ``enable_system_check`` --  toggles system-level health monitoring
+- ``status_ttl`` -- time-to-live for service status data
+
+
+.. _tcm_releases_1_5_0_testing:
+
+Testing improvements
+--------------------
+
+To make tests more efficient and predictable, all occurrences of ``time.Sleep`` were replaced with ``require.Eventually``.
+This change improves test speed and reliability. Additionally, HTTP checks and tuple insertion operations in tests were updated for better performance and accuracy.
+
+
+
+.. _tcm_releases_1_5_0_fixes:
+
+Fixes and compliance updates
+----------------------------
+
+This release includes multiple fixes across different modules:
+
+- CRUD and Explorer -- data types used during operations have been corrected to comply with FSTEC security requirements, ensuring strict typing and better protection of sensitive data.
+- Authentication -- the system no longer relies on etcd for storing authentication parameters. Instead, it uses local configuration to improve startup reliability and simplify setup.
+- Logging -- fixed issues with log output by switching to the ``slog`` logging system.
+- UI -- resolved display issues in the ``OperationStatus`` component.
+- Tuples -- fixed an error that caused tab refresh failures in clusters with a large number of spaces.
