TiUP has been upgraded to the latest v1.15.2 and failed to modify on TiDB 7.1.3:
[tidb@tidbtest bin]$ ./tiup cluster edit-config tidb-test
New topology could not be saved: Failed to parse topology file: yaml: unmarshal errors:
line 134: field additional_args not found in type spec.PrometheusSpec
Do you want to continue editing? [Y/n]: (default=Y) n

It can be successfully modified on TiDB version 8.0:
additional_args:

  • –web.enable-lifecycle

In the documentation for each version, this parameter is sometimes present and sometimes not. It is present in version 7.1, so should it normally be usable?

As long as the corresponding version is available, it can be used normally.

I tested it, and just upgrading the tiup version is not enough; you also need to upgrade the tiup component cluster version.
The documentation is not very clear about this.
tiup cluster -v
tiup version 1.15.2 tiup
Go Version: go1.21.10
Git Ref: v1.15.2
