Hello, I updated Polish translation of gajim. I used the gajim-0.16.6-74824f0bd5d4 version of gajim, opened the pl.po file, translated and saved. I attach the pl.po file to this email. It probably should be merged with the newest version of the translation from gajim 0.16.7. I did improve many existing lines in that file too, so the changes are not only to untranslated lines, but also to the ones that were translated already.
Regards.
