Where is the polish language?

I’m very disappointed, on this program is even fucking Slovak language, where there are few people.
so I ask when it will be Polish?

As Fritzing is free software and maintained by the community the translations are also based on contributions by the community. Thus there were some people from Slovakia who translated Fritzing to Slovak. If you would like to help translate Fritzing to Polish see here: http://fritzing.org/support-us/language-translation
