3.9.0 Upgrade Guide

SMB Versions in a File Reader/Writer

We added support for SMB versions 2 and 3 when using a File Reader/Writer. With "smb" as the selected method, click the wrench icon to view the SMB settings. There you can select the minimum and maximum supported SMB versions.

When upgrading Mirth Connect, existing channels will use "SMB v1" as the minimum version and "SMB v3.1.1" as the maximum version, in order to preserve functionality. However, SMB v1 is outdated and poses security risks, so we recommend updating your channels to use later versions of SMB. This may require also updating your SMB servers accordingly.

DICOM Sender Storage Commitment

In 3.9.0 we changed the functionality of the DICOM Sender option "Request Storage Commitment". Before 3.9.0, if a DICOM Sender with this option set to "Yes" failed to get a response to its storage commitment request, the sender would log an error to the server log but the message would still be considered successful. Now, in 3.9.0, if a DICOM Sender with this option set to "Yes" fails to get a response to its storage commitment request, the message will get the Error state. This means there's a potential for DICOM Senders to start encountering errored messages after the update but we feel that this is the proper behavior. You must either ensure the system you are sending to supports storage commitment or you can set "Request Storage Commitment" to "No".
