4.5.2 Technical Preview 1

We are pleased to announce the release of Technical Preview 1 of the Open Integration Engine — a community-maintained continuation of the open-source Mirth Connect project.

This release is functionally identical to Mirth Connect 4.5.2, with updated branding and groundwork laid for long-term open development. The “Technical Preview” designation simply reflects the project's new stewardship and packaging—not any lack of stability. It is fully suitable as a drop-in replacement for the original 4.5.2.

Scroll down to the "Assets" section on this page and expand it to see downloads and checksums.

Versioning

This release uses version number 4.5.2, matching the final open-source version of Mirth Connect. Maintaining the same version number ensures compatibility with existing tooling, integrations, and scripts, providing a seamless transition path.

What's New

  • Rebranding across the user interface and codebase to Open Integration Engine, designed for easier white-labeling
  • Java artifacts are now digitally signed (thanks to BrightCodeCompany)
  • vmptions has been refactored to include <install-dir>/conf/oieservice.vmptions and <install-dir>/conf/oieserver.vmptions, most users should do their overrides in the conf directory, not the root directory of the install.
  • Telemetry (sending usage or other information to an outside site) is disabled by default and can be enabled programmatically during white-label builds
  • Repackaged installers with updated metadata and simplified startup
  • Full installers available with or without a bundled JRE

Known Changes and Limitations

  • On Windows, you may encounter SmartScreen technology that warns you on download and during install. For larger downloads when you tell the browser to "Keep" (i.e. MS Edge) the download, it may take some time to finalize the downloaded file to your file system. We noted the delay from "Keep" to ready to execute during testing. The file appears to be fully written when the Open Integration Engine logo appears for the installer executable.
  • On MacOS, it wlll flag the installer as unknown, overrride that in System Settings... Privacy and Security, scroll to the bottom - the installer should show up there to allow you to override.
  • The original Web Admin interface has been removed and replaced with a minimal, read-only status page
  • The command line interface is bundled as oiecommand, there is no seperate installer. We will provide a standalone installer shortly. An existing client can still be used if needed.
  • The graphical “Mirth Manager” system tray tool has been removed due to incompatibilities with macOS launchd and modern Linux desktop environments
    • To configure: edit mirth.properties using any text editor
    • To restart: use the native service manager on your OS (e.g., Windows Services, systemctl, or launchctl)
  • Compatible with common launchers:
    • MCAL (a warning about the BrightCodeCompany certificate may appear; this certificate is valid and trusted. After first approval by you, you will not be prompted again )
    • Ballista
    • BridgeLink Launcher

Compatibility

  • Functionally identical to Mirth Connect 4.5.2: all connectors, transformers, and channel scripts should work as expected
  • The bundled installer includes a pre-configured JRE for faster setup

Downloads

Installers for all major platforms are available under the release assets.

Package Description
With JRE Recommended for easiest setup; includes Java
Without JRE For use with an existing Java installation

Call for Feedback

While this release has been internally validated, real-world environments vary. If you deploy or test TP1, we welcome your feedback—especially around tooling integrations, system behavior, or edge-case compatibility. Your input will help shape future releases.
