5.18.0

Release notes for 5.18.0.

Released: 2026-09-06

Features

• The package-default Design Token Panel builder now declares zdtp's native tier previews, so a host that does not supply its own buildDesignTokenPanelConfig gets tier previews out of the box (3f34e3d08).

Bug Fixes

• design-token-panel-bootstrap now adopts zdtp's isolated constants and exact activation gates instead of re-deriving them locally. The bootstrap had carried its own copies, which drifted from the package they mirror (cb2daf973).

Other Changes

• Saved Color overrides are now scheme- and mode-scoped. The package-default builder declares separate Default Light / Default Dark identities in panelSettings.colorMode, so an edit made in one mode no longer replaces the other mode's default or saved mapping, and returning to a mode restores that identity's saved choice. Palette, Spacing, Font, and Size overrides remain shared across light/dark within the active theme pack (026497e69).

• The @takazudo/zdtp optional peer requirement moves to ^0.5.0 (was ^0.4.14), across the 0.4.15 and 0.5.0 upstream releases (744b5c96c, a55182f9c).

• The @takazudo/zudo-doc-history-server optional peer floor moves to ^5.17.2 (744b5c96c). As always this names an already-published version and lags the in-flight release by design.
