please how update translations in Interlingua

[Giovanni Sora]

Hi,
please let me what I have to do to make translations file available with new 
releases of Calligra.
Let me explain.
I made translations in Interlingua (ia) but I do not see any translation file 
on newest release 2.9.x, (this is for any distro I looked for) while it was 
available for 2.7.x
Surely I made something wrong, please let me know what I have to do to be sure 
the translations are in.
Usually I translate on stable branche and on Kf5 trunk branche.
Thank you all
Regards
Giovanni Sora
