Centro 8.4.0 Release Notes


Along with importer updates and many bug fixes, Centro 8.4.0 includes many UI and workflow improvements and enhancements. It also introduces telemetry to help us make improvements in the future.

Special Installation Information!!

Actify anticipates releasing Centro 8.5.0 in a couple of weeks specifically to include Catia v5 2024 (3D) and Inventor 2025 (3D).

Let your organization's needs determine whether to install Centro 8.4.0 or wait for Centro 8.5.0.

Starting with Centro 8.4.0, support for Windows Server 2012 is being deprecated.

We strongly recommend migrating to Windows Server 2016 or later versions.

Installation Note Reminder

If running Centro on a Windows 10 or a Windows 2016 system, one must create a MIME Type for wasm, otherwise the SpinFire Web module fails to load models.

Windows 11, Windows 2019 and Windows 2022 systems have this MIME type set by default.
