Outdated Content Notice

Tralume can automatically show a warning banner on article pages when the content is older than a configurable number of days. This helps readers understand that the information may no longer be up to date.

Default behavior

By default, any article older than 180 days (approximately 6 months) will display an inline callout below the title:

⚠ This article was published over 180 days ago. The information may no longer be applicable.

The default threshold is defined in the theme partial (layouts/partials/outdated-notice.html) and applies to all sections (posts, pages, etc.).

Site-wide threshold

To change the default threshold for your entire site, add outdatedThresholdDays under [params] in your site config:

[params]
  # Note: Articles older than this many days will show the outdated notice.
  # Set to a larger value to be more lenient, or smaller for stricter aging.
  outdatedThresholdDays = 365

Per-page overrides

You can override the threshold for individual pages via Front Matter:

---
# Note: Override the threshold for this specific page.
outdatedThresholdDays: 90
---

To disable the notice entirely for a specific page:

---
# Note: Force-hide the outdated notice on this page.
showOutdatedWarning: false
---

Set outdatedThresholdDays to 0 to effectively disable the notice (any positive age will exceed the threshold).

How the date is determined

The age is calculated from the most recent meaningful date:

1. If the page has a lastmod field that differs from date, lastmod is used.
2. Otherwise, date is used.

This means an article originally published 3 years ago but updated last week will not show the outdated warning.

i18n

The warning text is managed via the i18n key outdatedWarning, which accepts a {{ .Days }} placeholder:

To customize the message, override the key in your site’s i18n/ directory.

Tips

• Use lastmod actively: Keep the lastmod field up to date when you revise content. This automatically suppresses the warning for freshly reviewed articles.
• Tune per section: If your site has sections with different content lifetimes (e.g., news vs. reference), adjust outdatedThresholdDays per page or section _index.md.
• Combine with showOutdatedWarning: false: Use this on timeless pages (e.g., “About” or “Privacy Policy”) that never need the warning.
• Editorial review: Consider pairing the outdated notice with a periodic review workflow — when you see the banner while reading your own site, it’s time to refresh the content.
