What's New
v72 adds host-based fake splitting, TCP sequence emulation, larger fake patterns, and blockcheck upgrades over v71.4.
New Features
- Host-based fake TCP splitting with selectable segment ordering via hostfakesplit options.
- TCP fake segment generation with sequence-number increments to emulate long multi-segment blocks.
- Fake payload offset selection and support for fake patterns up to 32KB.
- Windivert partial raw filters for more targeted packet filtering.
- Blockcheck additions including new strategies and OS/OpenWrt information display.
Improvements
- Fakedsplit now uses more default fake segments with adjustable segment ordering.
- IP ID handling is optimized across TCP segmentation modes and generalized for all OSes.
- Large fakedsplit patterns can span multi-packet requests using reassembly offsets and normalized split positions.
- Blockcheck gains simulation capabilities and richer environment reporting.
- Windivert filtering is more flexible through partial raw filter support.
Upgrade Notes
Treat this as a major-version upgrade and validate existing custom scripts and command-line options before rollout. New desync and Windivert flags are additive, but hostfakesplit/fakedsplit ordering and fake-offset behavior should be tested against your current profiles. Re-run blockcheck after upgrading to confirm strategy results and OS detection.
