Polyglot 1.13 - new liquid vars, SEO and redirect improvements

13 May 2026

Jekyll-Polyglot 1.13.0 has been released! This release is made possible thanks to support and many contributions from @rathboma and Beekeeper Studio.

better hreflang generation

• PR #282: @rathboma merged improvements to hreflang tag generation, adding a fallback option for unconfigured languages. This improves SEO and correctness of the generated headers on multilingual sites.

warnings on mismatched language codes

• PR #287: @rathboma added build-time warnings when a post’s lang: value does not match any configured site language. Language matching is now case-insensitive, so EN and en are treated the same.

• PR #290: @rathboma filtering now properly excludes posts written in languages that are not in the languages: config, preventing unconfigured content from leaking into builds.

localize Netlify _redirects

• PR #285: @rathboma added a new localize_redirects option. When enabled, Polyglot automatically generates language-prefixed copies of the Netlify _redirects rules, so a redirect like /github also works for /fr/github, /de/github, and so on. See the SEO recipes page for setup details.

new liquid variables for translation status

• PR #305: Two new liquid variables — page.missing_languages and page.available_languages — let your templates see which languages a page has been translated into, and which are still missing. Useful for building richer language switchers and sidebars.

new language translations

• PR #303: The Polyglot documentation site now has Ukrainian (uk) and Hindi (hi) translations, with help from AI-assisted translation. Corrections are welcome!
• PR #297: @manabu-nakamura contributed corrections to the Japanese (ja) site translations. Thank you!

AI development tooling support

• PR #298: Polyglot now ships with first-class engineering support for GitHub Copilot, Claude Code, and the shared AGENTS.md convention. AI is part of the workflow now, and contributions made with these tools are welcome.
• Additional CI quality checks were added, including htmlproofer and rubocop adjustments.

sidebar shows missing translations

The documentation site sidebar now flags pages that do not yet have a translation in the active language, making gaps easier to spot for readers and contributors.

Thank you to @rathboma and everyone who contributed to this release!
