WordPress version 5.0 came out a few weeks back at this point. I have upgraded most of my sites to the latest version. It has some pros and cons, but overall it was not a big change except for the new Gutenberg editor. This is what my experience was during the upgrade.
Wordpress runs about 30% of the websites on the internet in 2018, more than any other single blog or website system. It is a good choice in a content management system for many people because it has a lot of features that can be changed around easily to build a unique website.
