Slipstream — Classic proxy testing with SOCKS5 support
SlipNet — Full SlipNet configs support for DNSTT and NoiseDNS tunnels with SOCKS5 / SSH authentication and auto-detected auth method
DNS Scan — New lightweight mode: just insert a domain, set concurrency, and scan — no proxy testing, no authentication. Tests security, DNS types, ping, resolved IP, EDNS0, and more

🔀 New Scan Strategy — Bidirectional Multi-Range
Scanner now scans from the start and end of each IP range simultaneously across multiple ranges, combined with random shuffle — faster performance and higher chance of finding working DNS servers compared to linear scanning.

🧪 Auto DNS Type Check + Scoring
All DNS types (A, AAAA, MX, TXT, NS) are automatically tested and scored per server — same scoring system as the SlipNet scanner.

- Minimum proxy ping threshold for proxy test
- DNS connection timeout
- Proxy end-to-end test timeout
- Parallel proxy test count
- Custom shuffle steps
- Proxy test URL + expected response status code
- Set MTU (experimental OS-level MTU override)
- Query size for SlipNet (DNSTT / NoiseDNS)

Enhanced scan statistics — Redesigned stats display with clearer layout
Better result table — Improved writing and formatting in the results table
New proxy test status UI — Real-time proxy test feedback
Better Filtered IP detection — More accurate identification of filtered IPs
Log section always visible — Log panel is no longer toggleable; always shown during scans

Significantly higher scan performance overall
Auto detect auth method for SlipNet (DNSTT / NoiseDNS)

- Fixed crash on long-running scans caused by file descriptor leak — subprocess pipe handles are now explicitly closed after each proxy test, preventing the Windows select() handle limit from being exceeded

- Added Clear button next to the SlipNet URL input for quick one-click reset

- Added Minimum DNS Type Score setting in the Advanced section — configure the minimum score (1–6) a DNS server must achieve before it qualifies for proxy testing (default: 4)

- Added Proxy Test Try Number setting in the Advanced section — set how many times (1–5) to retry the full proxy test (tunnel + HTTP) before marking a server as failed

🔥 v2.0.4 Hotfix:

🔧 Improved proxy testing retry logic — each retry now restarts the entire tunnel process from scratch rather than only retrying the HTTP request, giving timed-out servers a genuine second chance

🔧 Fixed default expected HTTP status code staying at 200 instead of being auto-overridden to 204 when using a gen_204 test URL

🔥 v2.0.5 Hotfix:

🐛 Fixed Minimum DNS Type Score setting not being applied — a hardcoded threshold of 4 in the extra-tests safety net was overriding the user-configured value, causing DNS servers with scores 2–3 to be skipped even when the user set a lower minimum

🐛 Fixed "too many file descriptors in select()" crash — manually entered concurrency values now enforce the same hard cap (440) on Windows that auto-detection uses, preventing the SelectorEventLoop 512-fd select() limit from being exceeded
