XF 1.5 Update language file

[Mr. Jinx]

Is there a way to upgrade a language file without loosing the customization made to phrases?

 

[Mike]

No, as there isn't anyway to tell what's a customization that you made specifically. The only way to do this currently would be to do your customizations in a child language (though this will expose both languages to users).

 

[Mr. Jinx]

Ah ok. I was hoping that the same system as for templates was used for language files.
That way it would be possible to detect changes and merge/replace them.

FWIW, a similar system is used. You'd have the same problem with templates if you edited a third-party style directly and then tried to update it. There, you would need to make your changes to a child style and then the outdated templates (and by parallel, the outdated phrases) system would allow you to detect where changes need to be made.
