How to downgrade scribus file version?

Question

I'm currently using Scribus 1.5.1 development version and I want to downgrade to my 1.4.6 stable version. I want to import paragraph and character styles from my Scribus development file to a new file I make with stable version but there's no style shown which can be selected.

Is there a way to downgrade Scribus file from development to stable version (maybe it's because can't read backward version) or import the styles?

Thank you.

No, you cannot open a 1.5.x file in 1.4.x.
Nor exchange data in that direction.
Scribus -- like many other programs -- does not provide "forward" compatibility.

Theoretically, you can

• open the 1.5.x .sla file with a text editor,
• browse the xml soup to find out where the styles are defined,
• make a copy of your current 1.4.x file,
• open the copy with a text editor,
• browse the xml soup to find out where the styles are defined,
• paste the 1.5.x styles at the right place,
• tweak the definition of the new styles so that they look like the other ones in the 1.4.x document,
• open the 1.4.x file copy with scribus 1.4.x and hope for the best...

But you will probably be faster by recreating all the styles.

Of course, the other way round -- from 1.4.x to 1.5.x -- you should be able to import the styles.
