v2.6.5

V2.6.5 - August 5th, 2025

• Fixed a bug: During dispose, timerReport is not null checked before calling it to stop

V2.6.4 - July 14th, 2025

• The same conditions set in the document headers will be excuted before export begin to replicate the same environment as the import process.
• Both headers and footers will be verified before export begin.
• Removed the deprecated ExportInfo.SetTimeZoneUTC option in favor of unified headers/footers management. Export will now execute all headers, that includes setting the Timezone to UTC.
• New option for ExportInfo.GetTotalRowsMode: GetTotalRowsMethod.Auto, which is also the default mode. When there is no progress report events subscribed, it will use GetTotalRowsMethod.Skip. When there is progress reporting events subscribed, GetTotalRowsMethod.SelectCount will be used.

V2.6.3 - July 13th, 2025

• Change: ExportInfo.GetTotalRowsMode default value changed to GetTotalRowsMethod.Skip. Since the majority of users do not utilize progress reporting, this feature is now disabled by default to eliminate unnecessary time spent calculating total rows.

v2.6 - July 4, 2025

Major Highlights

🚀 Parallel Processing Support - New multi-threaded export operations with 3-phase pipeline architecture for dramatically improved performance on large datasets.

⚡ Enhanced Performance - Completely rewritten stream handling, optimized buffer management, and improved memory usage for faster exports.

🕐 UTC Timezone Management - Automatic timezone handling ensures consistent timestamp values and prevents data shifts during import/export.

Key New Features

• Table Column Value Adjustments - More flexible and performant column value adjustment system
• Table Locking Support - Optional LOCK TABLES WRITE for enhanced data consistency
• Exclude Rows Option - Ability to disable row export for specific tables
• Improved Error Handling - Better exception messages and validation
• Enhanced Progress Tracking - More accurate byte counting for import progress

Important Changes

• Breaking Change: The AdjustColumnValue delegate has been replaced with TableColumnValueAdjustments system

This release focuses on performance optimization and handling large datasets efficiently while maintaining backward compatibility for most use cases.

v2.3.9

V2.3.9 - March 12, 2025

• Introducing the AdjustColumnValue feature in ExportInformations. This new delegate (Func<ColumnWithValue, object>) allows users to dynamically modify column values during export. Paired with the new ColumnWithValue class (in MySqlConnector.InfoObjects), it provides table name, column name, data type, and value details for custom transformations. Ideal for data masking, formatting, or conditional adjustments, this enhances flexibility while maintaining default behavior when unused.

• Full change log: https://github.com/MySqlBackupNET/MySqlBackup.Net/wiki/Change-Log
• All binaries are built by referencing the latest dependencies.
  • mysql.data (Connector/NET) oracle - 9.2.0
  • MySqlConnector (MIT) - 2.4.0
  • dotConnect.Express (Devart) - 9.4.193
