5.20.0

Release notes for 5.20.0.

Released: 2026-09-09

Features

• Added dateFormat patterns with per-role and per-locale overrides for page metadata, history, note trays, and navigation. Patterns support YYYY, YY, MMMM, MMM, MM, M, DD, D, and bracketed literal text; omitted roles retain locale-based formatting. (2eeb42ce2, c126ecf8d, 1d8ba74fa, 10d5a90dc, 3a2dc81fe)

• Added optional LocaleConfig.description for each non-default locale's home hero. Omitted values use settings.siteDescription; an empty string intentionally leaves the description blank. This changes hero text only; llms.txt retains the global description. (0ce449ba0)

• Added namespaced --color-zd-* aliases and theme-no-reset.css, which preserves host color namespaces when stylesheet import order cannot be controlled. (f3aae4442, ecdc23800)

Bug Fixes

• Rendered sidebar and site-tree dates in the page locale, including single-locale sites without language-switcher links. Japanese month groups now read 2026年8月 rather than 2026 August; default numeric month/day and year-only labels retain their existing output. (47bd00ff4, 3c6c81c38)

• Separated history display locale from its storage path and formatted history timestamps in UTC, preventing browser locale or timezone from changing the displayed revision date. (30bcf88c8)

• Let home hero links wrap without squeezing Japanese labels, and wrapped long terminal breadcrumb titles while preserving the version pill's spacing. (be7b3de3b, 173fdb77f)

• Corrected theme-pack navigation hover contrast, including active items and text inside brutalist link cards. (6e561da45, 791ad2c92, c83b8bda5)

Other Changes

• Expanded the optional @takazudo/zdtp peer range to ^0.5.2 || ^0.6.0 || ^0.7.0. Existing panel integrations need no configuration or storage migration, and downstream pnpm peer-range exceptions can be removed. Continue importing @takazudo/zdtp/styles.css explicitly. (e0fc27fbd, 9554dbbea)
