Tomorrow, 6 Dec, WordPress 5.0 will be released.
WordPress is the most used CMS and a shitload of sites run on it.
The problem is that they've decided to integrate a broken editor called Gutenberg in the core. It's not just a mess in terms of usability, but it just doesn't work due to it being badly made Javascript bloat.
Despite the clear hate from the community, tomorrow normal people will update to 5.0 and find an editor they don't understand and probably many sites will break.
It's gonna be a fun day.
