There have been three major updates to Manjaro Stable since then, and the previous one — 2023.07.10 — was a huge update. I will admit that I’m running a fairly well-equipped system here, but that particular update replaced some 750 packages from the repositories alone — I’m not even going to get into the AUR stuff — worth over 11 GiB of space on my SSD once everything was installed.
That particular update also implemented the merger of the Community repo into the Extra repo, necessitating some manual intervention — rebuilding the package lists and updating the mirrors.
Although it is in theory possible to skip a few updates if you absolutely know what you’re doing, it is not the recommended strategy when using a rolling-release distribution like Manjaro, and especially not if one isn’t already an experienced user of said distribution.
