Minor Changes

• #​2777 88f4214 Thanks @​hippotastic! - Updates astro-expressive-code dependency to the latest version (0.40).

  This includes an update to the latest Shiki version (1.26.1), providing access to all current Shiki themes and syntax highlighting languages, and adding the config options shiki.engine, shiki.bundledLangs, shiki.langAlias and removeUnusedThemes. It also adds new style variants to the optional collapsible sections plugin.

  See the Expressive Code release notes for full details.

• #​2736 29a885b Thanks @​delucis! - ⚠️ BREAKING CHANGE: The minimum supported version of Astro is now 5.1.5

  Please update Astro and Starlight together:

  npx @​astrojs/upgrade

• #​2728 e187383 Thanks @​delucis! - Updates minimum Pagefind dependency to v1.3.0, sets new defaults for Pagefind’s ranking options, and adds support for manually configuring the ranking options

  The new ranking option defaults have been evaluated against Starlight’s own docs to improve the quality of search results. See “Customize Pagefind's result ranking” for more details about how they work.

• #​157 23bf960 Thanks @​tony-sull! - Adds a print stylesheet to improve the appearance of Starlight docs pages when printed

• #​2728 e187383 Thanks @​delucis! - Fixes Pagefind logging to respect the Astro log level. When using Astro’s --verbose or --silent CLI flags, these are now respected by Pagefind as well.

Patch Changes

• #​2792 412effb Thanks @​dhruvkb! - Uses semantic var(--sl-color-hairline) for the page sidebar border instead of var(--sl-color-gray-6). This is visually the same as previously but makes it easier to override the hairline color consistently across a site.

• #​2736 29a885b Thanks @​delucis! - Updates internal dependencies @astrojs/sitemap and @astrojs/mdx to the latest versions

• #​2782 d9d415b Thanks @​delucis! - Fixes a documentation link in the JSDoc comment for the StarlightExpressiveCodeOptions type

• #​2708 442c819 Thanks @​delucis! - Fixes colour contrast correction in code blocks
