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.
