Release notes for 5.27.0.
Released: 2026-09-24
Features
Added an accessible Appearance menu with Light, Dark, and System choices. System follows device changes, and the selected preference persists across navigation (5bb3d2175, d2146b6e0).
Bug Fixes
Grouped header icons into 40 px controls with no internal gap and 12 px boundaries beside other controls; the Appearance menu also returns keyboard focus to its trigger after closing (4c718aa02).
Kept the Appearance menu above the design token panel and within the available viewport (1773a3a21).
Corrected heading IDs and table-of-contents links when headings contain escaped punctuation or code spans (59d47f68a).
Other Changes
Raised the minimum supported zfb toolchain peer version to 2.20.2 (e22acafdf).
