You may update translation files with poEdit plugin. For this, you need to download the translation file open it and go to Catalog > Update from POT and choose the xstore.pot file from the new version of our theme. Then save your translation and upload new updated files to your server.
If we make changes in template files that change the position of strings with translation, you need to synchronize your old translation with new updated files. That’s why you should do this.
