There's no reason that you absolutely have to update every dependency after 6 months. Not updating anything at all is perfectly fine.
Nobody in their right mind thinks you can change major versions without some elbow grease in any other language.

I have an old project that I didn't touch in more than 5 years. Last week, I decided to give it another spin, and booked the entire afternoon to deal with any issues that may arise from the update process.
It went from Python 3.6 to 3.11, and from Django 2.2 to 4.2. Postgres jumped from 11 to 16! There were 10 other libraries (PIL, ...) that I had to update too.
The only special procedure that I had to do was dumping data from the old database and restoring it from the new one, as recommended by PG when doing major-point updates. (And adding a single line to Django's `settings.py` for the new `CSRF_TRUSTED_ORIGINS`.)
When I typed `docker compose up` on my terminal, the app just run smoothly without as single problem. I even had to check that I didn't invoke the old configuration by mistake.
All in all, the process took me less than 15 minutes.
