• For all but custom parameters, you need to use the built in Hugo variables, e.g. site.Title, site.LanguageCode; site.Language.Params.Title will not work.
• All custom parameters needs to be placed below params, e.g. [languages.en.params] in TOML.

I've a PR incoming that addresses this issue, but there is one consideration - the minimum version of Hugo that this project seeks to support.

Addressing the deprecation issue may well require incrementing the minimum version of Hugo from v0.97.1 to v0.112.0.

If increasing the minimum supported version of Hugo is a consideration that the hugo-PaperMod authors and contributors do not plan to support at the current moment, please feel free to ignore this issue for a while.

Looks like bep had second thoughts on this: gohugoio/hugo#11025

No longer a warning after 0.112.4
