Yes, I try and keep courses up to date, but please understand that it takes a lot of work as I revamp and re-record all videos and create new projects. I don't just throw in a couple of videos and call it an update.
All courses that we have here should be able to be followed without much trouble. I did not include my Udemy courses that are extremely out of date.
I am working on the MERN ECommerce course right now, which will be added very soon.
I will also release a Bootstrap 5 course soon to replace the Bootstrap 4 course.
