Garbage collector docs up to date ?

[timconsidine]

My docker registry app has ballooned in size to 333 Gb.

Docs say garbage collector :
/usr/local/bin/gosu cloudron:cloudron /app/code/registry garbage-collect /app/data/config.yml

But that doesn't seem to clean up.
GPT5.1 says that command is outdated and says it should be :
/app/code/registry garbage-collect --delete-untagged /app/data/config.yml

When I run that 'new' style command, disk usage drops to 14Gb.

I don't know which is right, just going by the results.

Can [@]staff please confirm which is right, and update app docs garbage collector section if needed.
