v1.6.0 - Statistically Speaking 📊

📝 Release Notes

⚠️ Warning: For multi-user Shadowsocks 2022 servers, upgrading to this release requires moving uPSKs into a separate file. See the updated project README for more information.

Server uPSK Changes

• Shadowsocks 2022 servers now use a separate uPSK store file for uPSK definitions.
• The server will reload the uPSK store file when a SIGUSR1 signal is received.
• Each uPSK is now paired with a username.
• The username can be used in routing rules.

Features and Fixes

• Added RESTful API for server user management and traffic statistics.
• Fixed data race in Shadowsocks 2022 UDP server that could result in incorrect uPSK being used for response packets.
• Major refactorings to the zerocopy package.
