03-25	Data Replication	Feature Optimization	Sybase incremental replication now spills oversized uncommitted transactions to disk before parsing, reducing memory pressure in large-transaction scenarios. Enhanced the robustness of Sybase CDC log parsing, improving stability for special-character and large-page-number scenarios. Fixed issues across OceanBase, SQL Server, MySQL, openGauss, Sybase, and other links involving incremental reads, JSON parsing, retry alerts, replication of tables without primary keys, and writes to identity columns.	Data Replication
03-18	Database DevOps	New Features & Enhancements	Added SQL Server Slow Query Analysis, SQL Server OnlineDML, and Oracle Job management capabilities. Improved the handling experience for large fields in the Oracle SQL Console. Optimized SQL task backup and data export pipelines for better execution performance; ChatDBA document parsing is now stronger and supports complex formats such as image-only PDFs and PPT-to-PDF files.

03-18	Data Replication	Feature Optimization	Failed repair statements now automatically distinguish DML from non-DML statements, reducing the chance of batch repair failures. Bidirectional replication now supports configuring DML conflict handling strategies separately for reverse links. OceanBase Oracle replication now supports XML data types; MySQL incremental DDL now supports table partition-related operations. Fixed issues with ineffective filter conditions, missing target-table columns, MySQL default-value parsing, and StarRocks primary-key and column-order handling.	Data Replication
03-11	Database DevOps	Feature Optimization	Optimized large-field handling and frontend-backend interaction performance in SQL Console, improving the experience with large result sets. ChatDBA knowledge-base Q&A has been upgraded to support parsing large files and images, and now answers in both Chinese and English. Fixed issues involving SQL standard cache, index recommendations in SQL intelligent optimization, and timeout handling.	SQL Console (RDBMS) ChatDBA
03-11	Data Replication	Feature Optimization	Added timeout control and higher parallelism to pre-checks, reducing task-creation wait time. Optimized incremental replication performance for large-scale specifications, further improving throughput when network conditions are good. MySQL incremental replication now supports table-based batch writes and transaction-level writes to the target; Oracle schema replication and incremental DDL now support keeping target tablespaces consistent with the source. Fixed replication issues in scenarios involving Oracle RAC and time precision differences across multiple MySQL versions.	Data Replication
03-04	Database DevOps	External Approvals (Lark)	External approval workflows now support Lark, allowing SQL tasks, permission applications, and other processes to be routed through existing enterprise approval workflows.	Lark Approval
03-04	Database DevOps	Slow Query Analysis	Slow log collection now supports Alibaba Cloud RDS MySQL, RDS PostgreSQL, PolarDB for MySQL, and PolarDB for PostgreSQL, providing broader coverage for managed cloud databases.	Slow Query Analysis
03-04	Database DevOps	Feature Optimization	Data Tracking & Rollback and OnlineDDL now support MySQL 8.4 and later. Permission applications are now supported for HANA data sources, improving day-to-day collaboration workflows.	Data Tracking & Rollback SQL Tasks Permission Application & Approval
03-04	Data Replication	Feature Optimization	Optimized incremental writes to improve throughput and stability for large-scale replication tasks. Changes involving foreign key dependencies are now applied in order to reduce data consistency risks during replication. Expanded compatibility for function-based indexes, primary keys with time zone types, and more data types in ClickHouse and Doris.	Data Replication
03-04	Basic Services	Message Notifications	Card-style notifications are now supported in Lark, DingTalk, and WeCom, with language settings for notification content to better support cross-team and cross-region collaboration.	Subscription Management

02-11	Data Replication	Feature Optimization	MySQL and OceanBase MySQL links now support replicating time default values with function expressions during schema replication and incremental DDL. MySQL and OceanBase MySQL links now support replicating table index definitions that include function-based indexes. Fixed issues with password placeholder handling during Kafka data source connection tests, as well as parsing and replication of SQL Server datetimeoffset types.	Data Replication
02-04	Database DevOps	SQL Console	The SQL Console now includes AI-powered suggestions that provide context-aware completions, with shortcut-based triggering and an on/off toggle. Currently supports MySQL-compatible, Oracle, and PostgreSQL data sources.	SQL Console (RDBMS)
02-04	Database DevOps	Slow Query Analysis	Slow Query Analysis now supports collecting external slow logs from Elasticsearch, which is useful when logs are centrally managed in a logging platform.	Slow Query Analysis External Collection Sources
