Angular 1.3.1June 18, 2026
Patched a hydration mismatch when theme="system" was used with server-side rendering.@slash.tools/react rendered light mode markup on the server regardless of the client's OS preference, which React would then flag as a hydration mismatch on first paint.
App.tsx
12345// Before: hydration warning on first paint<Slash apiKey={apiKey} theme="system" />
// After: matches automatically, no change needed<Slash apiKey={apiKey} theme="system" />- Fixed: hydration mismatch warning with theme="system" under SSR
- Fixed: flash of light mode before the client preference applied
