The latest major upgrade for WordPress is 5.4
Extend WordPress with over 54,000 plugins to help your website meet your needs. Add an online store, galleries, mailing lists, forums, analytics, and much more.
WordPress will also continue to support experienced users and developers who like to code websites and build customised solutions.As wordpress.org confirms:
If you’re more of an HTML and CSS sort of person, then the blocks won’t stand in your way. WordPress is here to simplify the process, not the outcome.
What if you don’t like change and just want to keep it classic?
Then you can choose to work with the original dashboard – for now.
WordPress will be supporting this classic feature until 2021.
