Allegro 17.4 always reports new files as created in 17.2

Hello. I am using Cadence 17.4 tools. When I open a package symbol (.dra) or board file (.brd) in Allegro that was created in an older version of the tool I get a message like this one (as expected):

"The design created using release 17.2 will be updated for compatibility with the current software..."


If I create a symbol or board file from scratch in the 17.4 tool then open it later, I get the same message. (always referring to version 17.2 which is the previous version I was using here).

So far this has not caused me any problems, but I would like to understand why it is doing this in case I have something setup incorrectly.

I only have version 17.4 installed. I am not exporting to a downrev version when I save (i.e. not using File->Export->Downrev design…) and in User Preferences->Drawing I don’t have anything selected for database_compatibility_mode. What else might I check?

FYI here is the tool version information that I see after selecting Help->About Symbol:

OrCAD PCB Designer Standard 17.4-2019 S012 [10/26/2020] Windows SPB 64-bit Edition


Thanks -Jason

    See the following article on Cadence Online Support:

    A .dra file saved using 17.4 release gives a message that it is created using 17.2 release when opened in 17.4

    Thank you!!! This answers my question and makes sense. I have seen other forum comments (and perhaps even some Cadence documentation) that states anything saved from 17.4 tools is saved as 17.4, so that added to the confusion.
