Three Key Highlights
First, Smart Split 2.0. The old version used domain allow/deny lists, which misjudged CDN-mixed or unregistered domains. Version 2.0 introduces a real-time IP database and flow feature recognition, lifting accuracy from 89% to 97%.
Second, 12 new Japan-Korea nodes: 4 in Tokyo, 2 in Osaka, 6 in Seoul, all on dedicated BGP lines with 40% more peak bandwidth.
Third, enhanced mobile kill switch. iOS and Android now block instantly and seamlessly, fixing occasional failures during background switches.
Smart Split 2.0 Explained
| Version | Split Dimension | Accuracy | Misjudgment |
|---|---|---|---|
| v3.7 | Domain lists | 89% | 11% |
| v3.8 | IP + flow features | 97% | 3% |
