#define KDBG_PACKET_VERSION (2)
#define KDAPI_PROTOCOL_VERSION (18)


// Kdbg protocol version number. this should be incremented if the
// protocol changes.
// ---- KD_PACKET_HEADER.dwRevision allocations ----
    // V1: until Jan 2004
    // V2: Simplified packet format with client GUID and simpler control (previous one redondant with KITL)

// KdApi protocol version number.  this should be incremented if the
// protocol changes.
// ---- DBGKD_COMMAND/DBGKD_NOTIF.dwSubVersionId allocations ----
    // V1: ?
    // V2: KdStub until Aug 99
    // V3: Temporary version (unused) for Processor Type (postpone to V5)
    // V4: Aug 99 - New Stack Walk: requires extra param (Frame Address) for TranslateRA
    // V5: Add ManipulateBreakpont
    // V6: Support returning PrevSP
    // V7: 256 BP + CPU Family
    // V8: New Module un/load notification with data section (Use DbgKdLoadSymbolsStateChange2) + Reset flag in case of exception too (sc.Thread)
    // V9: ARM VFP10 Support
    // V10: Intel Concan Support
    // V11: Return process handle for current call stack frame
    // V12: Support for Safe (non-forced) VM R/W and KdStub side sanitization
    // V13: Frame Pointer Optimization (FPO) disabled for x86 retail base functions (Will allow PB to unwind FPO frames)
    // V14: Return file time stamp data with load notifications
    // V15: Return hDll, dwInUse, wFlags, and bTrustLevel with load notifications
    // V17: Radically new protocol for eXDI2
    // V18: No more Mod load/unload notif + resync
