Mirth Connect 3.5 introduces around a hundred new features, improvements, and bug fixes. Enhanced filtering for channel names / tags makes it even easier to manage and monitor your interfaces. Filter / Transformer Iterators allow you to loop through segments and fields and map / extract data without having to write any JavaScript. This version also includes enhancements to attachment handlers, destination set filtering, the REST API, and many other features designed to make Mirth Connect channels even more powerful, and at the same time easier to create and manage. 

Channel Tag / Filtering Enhancements


Channel tags are easier than ever to configure and use. Simply start typing, and available channels / tags will show up in an auto-completion dialog.

  • Filter by channel tags, partial matches on channel names, or both at the same time
  • Quickly filter down to a specific channel
  • Display colored tag icons next to the channel names on both the Dashboard and Channels views
  • Add / remove / modify multiple tags across multiple channels in just a few clicks

In 3.4 we added Channel Groups for hierarchical organization of channels. These can be used in tandem with channel tags to allow organization from multiple angles! Each channel is under one group, but tags can still apply to multiple channels at once, even across different groups.

Filter / Transformer Iterators


Iterating through repeating segments / fields has always been possible in Mirth Connect, but now in 3.5 it's easier than ever, and doesn't require any custom JavaScript code!

  • Drag-and-drop wizard dialog helps decide what parts of the message to iterate on
  • See the flow control of your transformer scripts at-a-glance, without having to step through code
  • Supports multiple nested iterations

Attachment Handler Improvements

  • Multiple regular expressions, each with their own MIME types, supported in the Regex attachment handler:
  • New "Entire Message" handler added to quickly store the entire inbound message as an attachment
  • More attachment viewer options in the message browser:
  • Regex and JavaScript attachment handlers now support binary data
  • Source map variable replacement supported for MIME types
  • Use attachments across multiple channels

Destination Set Filtering Improvements

Destination Set Filtering was added back in 3.1, but now in 3.5 you can leverage this powerful feature without having to write any JavaScript!

  • New "Destination Set Filter" type available in the source transformer
  • Remove specific destinations, all except specific destinations, or all destinations

Other Features / Enhancements

  • REST API: Supports basic auth, CORS headers configurable in mirth.properties
  • DICOM Listener: A wide variety of source map variables are now available for use!
  • Database Reader: Now supports aggregating the results of a query into a single consolidated message, instead of dispatching multiple messages for each row
  • Reprocess / Remove Results: Additional confirmation / warnings added, so users cannot accidentally reprocess or remove multiple messages at once.
  • Channel Metadata: Changing pruning settings / tags or enabling / disabling a channel will no longer cause the channel revision to change
  • Password-protected ZIPs: When exporting or archiving messages to compressed ZIP files, you can now specify a password and encryption algorithm.
  • Easy List/Map Creation: New utility classes available in JavaScript contexts to create quick-and-easy Java Lists and Maps.
  • Security Updates: Updated cipher suites for SWEET32 vulnerability. Ephemeral Diffie-Hellman key size now 2048 to finish addressing Logjam. Added clickjack prevention headers to the REST API.
  • No labels
