🤖 New release

Changelog

[0.18.6] - 2026-01-05

Bug Fixes

• Accept variable-length MsvAvSingleHost AvPair (#580) (28f8d74b8c)

  Windows 11 Build 26200+ sends an 80-byte MsvAvSingleHost structure
  instead of the traditional 48 bytes. Per MS-NLMP specification, fields
  after MachineID MUST be ignored on receipt.

  This change:

  • Changes SingleHost from fixed [u8; 48] to Vec
  • Relaxes validation from == 48 to >= 48 bytes
  • Preserves full data for round-trip serialization

  Fixes RDP credential injection failures when clients use Windows 11
  Build 26200 or later.
