Release notes for 2026

March 12, 2026

This release adds Alibaba Cloud shared-storage PL0 disk support, improves the billing center marketplace overview, makes alert configuration more flexible, and adds read-only replica specification changes. It also introduces instance tag open APIs, temporary specification changes for subscription instances, and strengthens account security and email management on OceanBase Cloud (International Site).

Products and channels

OceanBase v4.4.2 LTS now available

• OceanBase v4.4.2 LTS is a unified TP/AP LTS release for mixed workloads. It combines the transaction processing strengths of v4.2.5 LTS with the analytical capabilities of v4.3.5 LTS and improves the engine across data management, compatibility, security, and operations. It provides stronger, more stable support for both critical transactional and complex analytical workloads.
• This version is currently available by allowlist. Contact the OceanBase support team to get access.

Baidu Cloud channel

• The tenant workbench now shows the instance name so you can identify instances at a glance.
• Cloud disk storage can be expanded by self-service.

Alibaba Cloud channel

• Shared-storage cache disks now support the PL0 (cost-optimized) disk type.

Database operations and maintenance

• Monitoring: Comparison charts are improved for better readability.
• Alerting: Alert notification templates no longer restrict by object type, so configuration is more flexible.
• Read replicas can use a different specification than the primary.
• Subscription cluster instances support temporary specification changes to meet short-term capacity needs.

Data development

• ODC (standalone) now supports online schema changes.

Security and compliance

• OceanBase Cloud (International Site) supports organization-level MFA. After an org admin enables it, members must complete a second authentication step on their next login.
• OceanBase Cloud (International Site) supports changing the account email so users can update their contact information.
• When signing in via a third-party provider on the International Site, accounts that share the same email require a second confirmation to avoid linking the wrong account.

Billing

• The message center supports custom subscription rules by message type and channel.
• When an instance is automatically restarted after being paused for 7 days, an in-console notification is sent.

Ecosystem integration

• Binlog subscription:
  • Binlog metric descriptions are clearer and more accurate.
  • Metrics can show full subscription status, and you can run statistics and analysis over a custom time range.
• ODC (standalone) supports online schema changes.

Open API

• Backup strategy: New APIs to configure and manage backup policies programmatically.
• Scheduled logical backup: New API to set up recurring logical backup jobs.
• Tenant backup and restore: New APIs for tenant-level backup and restore.
• Backup task status: New API to query backup job status for automation and runbooks.
• Security assessment: New API to query instance security check results.

January 7, 2026

This release introduces new data migration tasks between PostgreSQL, TiDB, and OceanBase Database, expands support for database migration to the cloud, and provides independent data validation and tag management features. It also enhances task management, improves the stability of migration validation tasks in multi-cloud environments, and boosts the flexibility and stability of data operations.

New data migration tasks

This release introduces new data migration tasks from PostgreSQL to OceanBase Database (MySQL and Oracle compatible modes) and from TiDB to OceanBase Database (MySQL compatible mode). These tasks support schema migration, full migration, and incremental synchronization, helping you quickly migrate data from PostgreSQL and TiDB to OceanBase Database. Additionally, new data migration tasks from OceanBase Database (MySQL and Oracle compatible modes) to PostgreSQL and from OceanBase Database (MySQL compatible mode) to TiDB are introduced, supporting incremental synchronization. These features allow you to synchronize data from other databases to OceanBase Database and then back to the source databases, meeting disaster recovery and business continuity requirements.

New data validation capabilities

In this release, data validation is separated from the data migration process and can be configured independently. This allows for more flexible operations without relying on the data migration workflow. In addition to full data validation, row count validation is now supported. This feature enables you to verify data by comparing the number of rows in table objects, significantly speeding up the validation process. Currently, full data validation and row count validation are supported for the following task types: MySQL -> OB_MySQL, OB_MySQL -> MySQL, OB_MySQL -> OB_MySQL, Oracle -> OB_Oracle, OB_Oracle -> Oracle, OB_Oracle -> OB_Oracle, PostgreSQL -> OB_Oracle, PostgreSQL -> OB_MySQL, and TiDB -> OB_MySQL.

Tag management capabilities

This release integrates tag management with data migration and data validation. Using the tag management feature on OBCloud, you can add tags to data migration and data validation tasks and filter tasks by tag on the task list page. This helps you better manage data migration and data validation tasks based on business attributes.

Stability enhancements

• For data migration tasks with a PostgreSQL database as the source, incremental synchronization now defaults to using unique keys on the target database to determine conflict matrices. This avoids data quality issues caused by incomplete schema information in PostgreSQL database logs.

• The incremental synchronization logic has been optimized to resolve the issue where original incremental DDL synchronization would block all subsequent DML executions. The serialization logic has been refined to the table level, meaning that DDL synchronization no longer blocks DML synchronization for unrelated tables.
