• Better recovery from disconnected service endpoints

The core lifecycle is now managed through the new actor-based CoreControl architecture.

System proxy and networking

• Added PAC proxy support with download, validation and fallback
• Improved system proxy handling
• Configurable Mixed / SOCKS5 / HTTP port strategies
• DNS cache management
• Improved TUN permission handling
• Improved system-service management
• Windows service communication now supports named-pipe control

Tray improvements

• Configurable tray menu behavior
• Configurable tray icon
• Optional tray traffic display
• macOS colored tray icons
• Improved proxy selection behavior
• New tray-menu implementation groundwork

Internationalization

The localization system has been migrated to @inlang/paraglide-js.

Other improvements include:

• Automatic language selection from the system locale
• Added Korean translation
• Improved Traditional Chinese support
• Extensive Simplified Chinese, Traditional Chinese and English translation revisions
• Improved tray-menu localization
• Localized connection table and detail fields
• Day/date formatting follows the selected application language

Performance

A major focus of 2.0 has been reducing unnecessary rendering and improving responsiveness.

Notable improvements include:

• Significantly lower render cost on Connections
• Significantly lower render cost on Logs
• Faster Rules page rendering
• Reduced frame drops when switching proxy groups
• Reduced application-wide re-renders caused by WebSocket updates
• Stable profile/provider references between refreshes
• Connection detail streams are only sent to subscribed pages
• Proxy nodes are transferred once and referenced by name
• Large profile diffs are rendered incrementally
• Large highlighted YAML documents are cached or skipped when appropriate
• Monaco editor is no longer included in the main application bundle
• Shiki syntax highlighting is loaded lazily
• Settings sections are rendered incrementally
• Dashboard widgets no longer rerender for unrelated sample updates
• Scroll, tab, marquee, logo and sparkline animations have been moved toward compositor-friendly paths
• Improved WebKit rendering performance

Reliability and architecture

2.0 contains a major backend architecture migration.

Key areas include:

• Migration from Tauri v1 to Tauri v2
• Actor-based application state management
• Typed configuration actors
• New runtime pipeline
• New profile domain model
• Typed IPC and RPC APIs
• Cross-transport RPC infrastructure
• tauri-specta-query integration
• New NyanpasuClient facade
• Centralized PathResolver
• Reworked application lifecycle and shutdown
• Structured backend errors
• Improved service IPC recovery
• Configuration convergence and mutation tracking
• Improved migration validation and recovery
• Automatic configuration backups before migrations
• Runtime state snapshots

Many legacy global state objects and configuration bridges have been removed.

Breaking changes

Clash Nyanpasu 2.0 includes several major compatibility changes:

• Migrated from Tauri v1 to Tauri v2
• Legacy UI has been removed
• Profile configuration now uses the new profile domain/pipeline model
• Application configuration is migrated into typed state files
• Core lifecycle has moved to the new CoreControl architecture
• Internal IPC interfaces have been redesigned
• Hardware AES is now part of the baseline requirement for distributed x86 targets
• 32-bit x86 (i686) builds have been dropped
• ARMv7 / armel / armhf builds have been dropped
• OpenSSL has been removed in favor of rustls
• HTTP networking has migrated from isahc to reqwest
• macOS builds now use the Xcode 16 toolchain
• Mihomo amd64 variants have moved to the v2 packaging format

Because the configuration and profile systems changed substantially, configuration migration is automatically performed when upgrading.

Nyanpasu now creates backups before migrations, but keeping an additional manual backup is recommended when upgrading from older versions.
