NoBrand-OneClick 3.0.0

NoBrand-OneClick 3.0.0

NoBrand-OneClick 3.0.0 is a clean-break release built around one installer, one canonical manager, and one schema-v3 ownership model. It does not automatically migrate legacy users or state.

Highlights

• One release installer: install-nobrand.sh
• One canonical manager: nobrand, with nb as its short alias
• Full Mieru feature and parameter parity, including Profiles, defaults, multi-user instances, quota, tc/rate limits, Display Endpoints, diagnostics, backup, and client exports
• Snell v5 as the stable, recommended default, with optional official QUIC server exposure; Snell v4 remains available for compatibility
• Hysteria2 over Xray-core
• Plain VLESS with FinalMask/Sudoku over TCP and VLESS Encryption disabled
• Unified nodes, Display Endpoint handling, backup/restore, ownership tracking, and project-wide uninstall
• Clean schema-v3 state with no automatic legacy-user or legacy-state migration

Snell v1, v2, v3, and v6 are unsupported and have no hidden installation path. The former install-mita.sh and NoBrand management wrappers named mita have been removed; the genuine upstream Mieru runtime continues to use its official mita binary name internally.

Client compatibility

Protocol	Verified clients	Unsupported or unverified combinations
Mieru	Mihomo; official Mieru reference client	sing-box unsupported
Snell v4	Mihomo; sing-box	—
Snell v5 with public QUIC exposure OFF	Mihomo; sing-box	Official QUIC-wire Linux E2E not verified
Hysteria2	Mihomo; sing-box	—
VLESS FinalMask/Sudoku	Xray-core reference client	Mihomo and sing-box unsupported

Official Snell v5 QUIC server exposure is supported. This release does not claim verified Mihomo official QUIC-wire interoperability, and sing-box does not support official Snell v5 QUIC Proxy Mode.

Breaking changes

• State and ownership now require the clean schema-v3 model.
• Legacy Mieru/NoBrand state is detected and rejected without being imported, converted, modified, or deleted.
• install-mita.sh and NoBrand mita management compatibility have been removed.
• nobrand uninstall now removes all resources explicitly owned by NoBrand 3.0 across Mieru, Snell, Hysteria2, VLESS/Sudoku, and common state, while preserving external resources.

Validation

The release passed deterministic builds, syntax and ShellCheck gates, unit and runtime suites, complete Mieru parity gates, four-platform container coverage, ownership and uninstall boundaries, protocol regressions, and non-destructive real-machine health validation.

Known limitations

1. The Linux client matrix does not provide a verified official Snell v5 QUIC-wire end-to-end implementation.
2. Mihomo and sing-box do not support VLESS FinalMask/Sudoku; Xray-core is the reference client.
3. VLESS/Sudoku showed lower upload throughput in the tested lab despite correct connectivity and data integrity.
4. Snell v5 may require a reasonable connection cadence immediately after a fresh client process starts.
