I have placed the release announcement for openSUSE Leap 15.4 on the wiki at https://en.opensuse.org/Release_announcement_15.4
It would be highly appreciated if you could help to translate the release announcement to your native language to help propagate the news of our next release. Currently it is only in English. Feel free to link your translated version to the top and include your ISO 639-1 Code language code. If you have any questions, please let me know.
Also, please consider updating the screenshots once we have the RC. You will find old screenshots on https://en.opensuse.org/Portal:15.4/Screenshots and new screenshots will just need to be uploaded and updated.
Thx Carlos for letting me know it didn't post. Hopefully this works.
