Managed File Transfer Release Notes for August 2026

New

We added these features

Introduced metadata tags for Flow Endpoints. Add name/value tags through the API or Flow Studio, then view and filter Activity results by those tags. (AFT-727, AFT-728, AFT-730, AFT-948, AFT-949)
Reduced the delay between file arrival and transfer start on OnArrival flow schedules, from up to 30 seconds to under one second. (AFT-715)
Introduced antivirus scanning for the Windows MFT Runtime (Node), which scans files with Microsoft Defender during transfer and reports results to the Control Plane. Disabled by default; enable it in Node configuration. (AFT-493)

MFT Runtime
Improved runtime queue reliability, resolving intermittent data corruption and transaction-limit failures seen under high transfer volume. (AFT-1107, AFT-1108)
Streamlined runtime heartbeat history by removing duplicate entries from rejected and resumed heartbeats. (AFT-432)

Fix

We fixed these issues

Fixed an issue where the loading icon never resolved on the File Activity page due to repeated getFileActivity requests. (AFT-1177)
Resolved an issue where a delayed recurring flow schedule could silently skip a run instead of catching up, causing flows to execute less often than configured. (AFT-1125)

MFT Runtime
Node heartbeat re-registration no longer sends a stale timestamp after a brief connectivity interruption, preventing false "Node heartbeat timed out" alerts. (AFT-1185)
Resolved an issue where a flow's scheduled runs kept targeting its previous MFT Runtime after the runtime was changed, causing connection errors until the flow was run manually. (AFT-1305)
