Just wanted to add a few items.
Follow the Announcements in this forum, specifically Stable and Releases. You can view them in this forum or as RSS Feeds. I see you are using KDE. The KDE application will be Akregator. An annoucement post will not only inform you that something new is available, but it will let you know if there are any manual actions you might need to take or of any problems that users might be having. As @SamLukeYes described, Manjaro is a Rolling Release verses a Fixed Release model of distributing software.

Definitely take advantage of the search feature of this forum. This forum was re-created earlier this year and previous posts were archived. Simply take this url and add archived to the front of it (i.e., https://archived.forum.manjaro.org/). This archived forum can also be searched.
When I first got on this forum, users suggested I view the New posts and open the ones I was interested in, in a new Tab and when I reached the botton of the New posts, click Dismiss. This helps in staying current and efficiently getting through posts. Threads that I want to follow, I will go to the bottom and mark as Tracking and they will appear under Unread verses New.
One thing new users need to do is select the location of their repositories. There are approximately 99 different mirrors throughout the world. You can either run pacman-mirrors or edit the file in “/etc/pacman.d/mirrorlist” which is where the run-time mirrors are stored. The GUI will use these repos. Check the file first and if the locations look okay, you’re done.
The status of repositories is located at: https://repo.manjaro.org/.
Doc regarding the command pacman-mirrors: Pacman-mirrors - Manjaro. Ignore the pacman specific commands since you are using a GUI.
