[1.36.0] - 2026-02-16

  • IMPROVED: Connections Table — moved the streaming/paused control from the top control bar to a floating play/stop button in the bottom-right corner of the table for a cleaner UI.
  • IMPROVED: Set Editor Redesign — simplified the tab layout from 7 tabs down to 5. Fragmentation and Faking tabs are now part of the TCP section where they belong, since both techniques operate on TCP traffic.
  • TCP tab now has 3 inner tabs: General (connection limits, timing, duplication), Splitting (all packet splitting strategies), and Faking (all evasion techniques in one place).
  • Faking groups related settings into collapsible sections (Fake SNI, SYN Fake, Desync, Window Manipulation, Incoming Response Bypass, ClientHello Mutation) — each section shows its current status at a glance so you can see what's active without opening it.
  • UDP, DNS, Targets, and Import/Export tabs remain unchanged.
