  • For many of us, 2020 has been a difficult year. As we pass the end of 2020, many things are still not over yet. But we should all be ready for the opportunities and new challenges 2021 is about to present to us. We are releasing this new version on the first day of 2021. And we wish you a happy new year! ??
  • Security update: Yes, we have finally removed support for all stream ciphers, almost 4 years after the proposal of Shadowsocks AEAD. Stay safe! ??
  • Prepare to say goodbye to legacy links! When importing servers from pre-SIP002 legacy ss:// links, we will show a warning message to remind you to update your ss:// links. The easiest way to update is to use the server sharing feature.

New in Shadowsocks 4.3.0.0 (Oct 19, 2020)

  • When in whitelist mode, Chinese domains, including non-Chinese companies' Chinese CDNs, are connected to directly.
  • When in blacklist mode, only non-Chinese domains goes through the proxy. Chinese domains, as well as non-Chinese companies' Chinese CDNs, are connected to directly.
