Recently in December first week 2018 WordPress new version 5.0 has released but it has numerous bugs so most of the websites stopped working when they updated to WordPress 5.0, they named it as "Bebo" version with building blocks features, using this feature user can edit text without html knowledge, it works like visual editor.
After that they come up with 5.2.0 or WordPress 5.2 version. They fixed free bugs in it, but still there are so may issues like inactivity of plugins.
