PR checklist

Please check if your PR fulfills the following requirements:

• I have read the CONTRIBUTING.md doc
• The Git workflow follows our guidelines: CONTRIBUTING.md#git
• I have added necessary documentation (if appropriate)

Unsure if this requires configuration usage documentation.

What is the current behavior?

Currently iVPN has a link to mastodon but it lacks rel="me", meaning iVPN does not appear verified on Mastodon.

The iVPN site also does not include noopener or noferrer on external social links.

The changes detailed in the next section allow the rel to be customized within config.toml, allowing these problems to be addressed individually.

What is the new behavior?

Now footercolfour links in the config.toml can be configured to have a rel. If one does not exist, it will not add the rel definition at all. This accomplishes three tasks:

• Allows external links to be configured with noopener, preventing tabnapping.
• Allows verified links with services such as Mastodon.
• Allows adding noreferrer, optionally, this is intentionally the last commit so it can be easily chopped off.

Note in the config.toml file the mastodon definition includes me . iVPN already includes the proper link (without the me) on their site, but their Mastodon profile lacks verification. This modification would allow the site to automatically become verified on Mastodon with no further effort. Relevant links for this:

• https://joinmastodon.org/verification
• https://mastodon.social/settings/verification

Does this PR introduce a breaking change?

• Yes
• No

Current changes don't compile, there's an error:
https://github.com/ivpn/ivpn.net/actions/runs/7907442820/job/21602031191?pr=740

executing "partials/footer.html" at <.Rel>: can't evaluate field Rel in type *navigation.MenuEntry

I'll also try to troubleshoot.

Built with local Hugo, my bad. I will troubleshoot later with the proper build.

[aaofyi]

Okay I have found the issue, it lies with custom parameters in the Hugo Menu.

The output of .Hugo.Version for the site is: 0.76.3

Custom Hugo parameters for the menu were added in Hugo version 0.79.0.

I will be adding one more commit that fixes the parameter definition. Otherwise this PR should just be held until the site updates to a newer Hugo version.

@aaofyi OK understood, thanks for the info. I'll check if I can upgrade Hugo to latest version without braking anything on the site.

If you update to Hugo >= 0.110.0, you may want to rename the config.toml files to hugo.toml in the src/config directory. This caused me a few headaches in the past.

This change is detailed in Hugo's docs:
"With v0.109.0 and earlier the basename of the site configuration file was config instead of hugo. You can use either, but should transition to the new naming convention when practical."

OK understood. Thanks for the heads up.
