Release v4.0.2
Pre-release
⚙️ Cloudflare ECH
ECH option is added to BPB Panel now for all cores. Please note that this is not so helpful in Iran regarding tests, successfully connects but gets banned after a while on some ISPs. This option can be more helpful in other countries.
Tip
ECH applies only to Normal subscription, not Fragment.
Tip
BPB queries ECH config within worker and does not delegate ECH config query to client core which is an advantage (core query may fail due to DNS query failure or blocked domains). So there's no extra settings, you can just enable ECH from panel and use it.
Note
These days Fragment on some ISPs stopped working in Iran, you can change Fragment packet to 1-1 instead of tlshello and test, also you can try to change Fragment mode to bypass IR-GFW.
Caution
If you are upgrading from versions below 3.5.1 to 4, you should get subscriptions from panel again.
Caution
sing-box client version should be 1.12.0 or higher.
Caution
Xray clients should be updated to the latest version i.e. v2rayNG, v2rayN and Streisand.
