Sage have posted the first product update for their latest MAS90 4.5 release. This product update includes a very helpful section which provides information on what files are converted (if any) when you load the product update.
Previously there was no way to know if a lengthy data conversion was going to kick off or if the product update might impact a customization that was installed on your system. The new changelog (view here) provides these details and should be helpful when deciding on the timing of the installation.
