Some notable new features in Hugo v0.151.0 are:

• New transform.HTMLToMarkdown template function. One possible use case would be to provide LLM friendly content.
• Hugo now reports OSC 9;4 progress when building; progress bars/indicators are supported by terminals such as Ghostty on Macos and Linux, Windows terminal.
• Several new config options for Markdown foot notes.

Note

• transform/livereloadinject: Skip livereload.js injection if no tags found (note) 7fd6762 @AndrewChubatiuk

The big new feature in this relase is the new version config option on Module imports, which allows you to set the requested module version query directly in your Hugo configuration (e.g. hugo.toml). This is a feature that have been requested by many, and I (@bep) was reminded about it by this recent thread, which also outlines a common use case for this: Mounting multiple old versions/branches of API documentation into the project.

What's Changed

• build(deps): bump golang.org/x/mod from 0.27.0 to 0.28.0 d1f6a1d @dependabot[bot]
• modules: Add support for direct version module imports in hugo.toml 747cf4a @bep #13964
• resources/page: Fix truncated summary logic d8774d7 @jmooring #13967 #13968
• config/security: Add PROGRAMDATA to the osenv allowlist 3b8947d @jmooring

The main motivation behind this release is the Go 1.25.1 upgrade, which comes with a security fix. Hugo does not use the feature in question, but we understand that many Hugo users like to have a clean security report.

Note

Note that CSS minification now targets CSS3, removing certain optimizations that were specific to CSS2.
