SOTA: Hugo Static Site Generator

As of 2026-07-28. Mode: survey (repo-grounded against PKB-theme). Freshness: findings older than 12 months are flagged [STALE]. Every numbered claim ends with its source and access date; anything unverifiable is marked [UNVERIFIED].

TL;DR

• The latest Hugo release is v0.164.0 (2026-07-06). Roughly 25 minor releases shipped in the last 19 months; the project is very actively maintained, still centered on Bjørn Erik Pedersen.
• The big theme-author events of the period: the v0.146 template-system rewrite (new layouts/ structure), v0.148 render-hook useEmbedded enums (replacing enableDefault), the v0.156 mass removal of long-deprecated APIs, v0.158 languageCode → locale, v0.163 per-format imaging config, and v0.164 resources.PostProcess → templates.Defer.
• PKB-theme’s in-progress migration to useEmbedded = 'fallback' is correct (minimum version v0.148.0, verified). But its CI pins Hugo 0.123.7 / 0.128.0 - below the theme’s own min_version = "0.136.0" and far below the README’s new “v0.148+” claim. Aligning versions is the top action.
• Concrete code updates for this repo: replace .Page.Scratch (deprecated v0.138.0) in the cite/sidenote shortcodes, move the global imaging.quality into per-format blocks, rename languageCode → locale, and audit two non-standard render hooks (render-inline.html, render-paragraph.html) that are not part of Hugo’s documented hook set.

Landscape

Release train & maintenance

Hugo ships a minor release roughly every 3–5 weeks with patch releases in between. From v0.140.0 (2024-12-17) to v0.164.0 (2026-07-06) there were 25 minor lines, the majority of which introduced at least one deprecation or small breaking change - Hugo deprecates aggressively and removes on a ~6–18 month horizon. Maintenance is healthy but concentrated: bep accounts for ~60–68% of commits; jmooring is the most visible secondary maintainer; ~210 open issues with closure rate exceeding creation rate over the last year.
