v2.1.0

Multiline JSX class extraction, stricter token-backed CSS z-index enforcement, explicit CSS allowances, and version-aware documentation navigation.

This release closes the remaining multiline class-extraction gaps, strengthens the opt-in CSS z-index rule, and retires documentation workarounds now covered by current zudo-doc releases.

Class Extraction

• Configured JSX/Astro class attributes now use balanced {...} scanning across physical lines. Array/join expressions, nested calls, and conditional strings inside template interpolations are extracted with their true source lines instead of being silently skipped (eda079b).

• Attribute template literals emit their static class segments and scan literal strings inside ${...} branches without reporting interpolation source as a class. Nested configured functions are deduplicated, and comment/ignore metadata remains intact (eda079b).

• Malformed or unclosed attribute expressions retain the existing 50-continuation-line safety boundary rather than consuming unrelated source (eda079b).

CSS z-index Rules

• css.zIndex now rejects token-less calculations such as calc(70 + 1). Direct var(...), calc(...) expressions containing var(...), and standard CSS keywords remain allowed (6abf8e6).

• An object form adds explicit raw-integer exceptions: "zIndex": { "allowed": [0] }. The existing boolean form and exported CompiledCssConfig.zIndex: boolean contract remain backward compatible (6abf8e6).

• CLI, config validation, browser Playground parity, README, and the English/Japanese reference documentation now describe and test the same behavior (6abf8e6, d71924c).

Documentation Site

• Upgraded zudo-doc integration now uses the configured nested entry document, keeps archived CategoryNav links inside their version, renders latest-only Claude navigation canonically, and disables unavailable archive switcher destinations (3b44451).

• Superseded entry-page and Claude redirects were removed. Legacy /v/:version/docs/claude* paths now intentionally return 404 rather than serving current content under an archive label (3b44451).

• Strict link checking ignores only anchors explicitly marked aria-disabled=true; active links and redirect targets remain fully validated with zero allowlisted exceptions (3b44451).

• The v2.0 documentation snapshot remains available and is now marked unmaintained because v2.1.0 is current.

Maintenance

• Refreshed the zfb/zudo-doc toolchain and aligned its template-drift policy (b6d0c5e, aa01f5e, 7356b7f).

• Updated the CI cache action and automated the release-time archived-doc banner transition (609f111, bb5bed4).
