# Batch Communications Engine October 2026 (26.3.6) Release Notes

## Overview

The 26.3.6 release of Batch Communications Engine (BCE) improves notification delivery reliability, campaign and campaign-run search performance, large-result pagination, profile export processing, and OpenSearch data handling. The release also includes user-interface refinements, campaign data fixes, and backend support for the upcoming User Management and Request Access screens.

## Continuous Improvements

- BCE now sends each notification only once, retries failed notifications, and improves overall reliability and performance.
- In BCE, searching for campaigns is now faster and more responsive. Campaign searches use an optimized server-side search instead of loading the full campaign list page by page. The Campaign run history panel also loads faster and uses fewer API calls.
- BCE now displays 20 items per page by default. You can change this number using the options button in the lower-right corner.
- The Auto Opt-In button has been updated to match BCE’s standard user interface design. This change improves visual consistency with other buttons and controls across the product.
- Fixed an issue with imported subscription data that could cause search problems. The data is now stored more efficiently, improving search performance and reliability.
- Fixed an issue that could affect record retrieval when multiple records had the same creation time. BCE now uses a more reliable process to retrieve all records.
- Fixed an issue that caused errors when viewing more than 10,000 results. Users can now continue paging through results beyond this limit.
- BCE now delivers each notification only once to the intended system, such as XVM or PrecisionEmail. It also automatically retries failed notifications so no events are lost.
- Fixed an issue where the campaign run panel did not display the campaign end date after a campaign was run. The end date now appears correctly.
