symptom and fix
major · >=0.42.0 · published · verified 2026-09-08
Custom styles for the mobile menu button stop applying, and `tagline` is rejected in the config.
0.42.0 dropped the `<starlight-menu-button>` wrapper and the `aria-expanded` attribute; target `.sl-menu-button` and style the open state with `:has(~ :popover-open)`. The unused `tagline` option was removed. This release also requires astro v7.2.10 or later, so upgrade Starlight and Astro together.
