  • v1.3-beta2 - 21 Jul 2014

    • Changed the parameters to Windows-friendly types. (void* to LPVOID)
    • Fixed some small bugs.
    • Reorganized the source files.
    • Reduced the footprint a little more.
  • v1.3-beta - 17 Jul 2014

    • Rewrote in plain C to reduce the footprint and memory usage. (suggested by Andrey Unis)
    • Simplified the overall code base to make it more readable and maintainable.
    • Changed the license from 3-clause to 2-clause BSD License.
  • v1.2 - 28 Sep 2013

    • Removed boost dependency (jarredholman).
    • Fixed a small bug in the GetRelativeBranchDestination function (pillbug99).
    • Added the MH_RemoveHook function, which removes a hook created with the MH_CreateHook function.
    • Added the following functions to enable or disable multiple hooks in one go: MH_QueueEnableHook, MH_QueueDisableHook, MH_ApplyQueued. This is the preferred way of handling multiple hooks as every call to MH_EnableHook or MH_DisableHook suspends and resumes all threads.
    • Made the functions MH_EnableHook and MH_DisableHook enable/disable all created hooks when the MH_ALL_HOOKS parameter is passed. This, too, is an efficient way of handling multiple hooks.
    • If the target function is too small to be patched with a jump, MinHook tries to place the jump above the function. If that fails as well, the MH_CreateHook function returns MH_ERROR_UNSUPPORTED_FUNCTION. This fixes an issue of hooking the LoadLibraryExW function on Windows 7 x64 (reported by Obble).
  • v1.1 - 26 Nov 2009

    • Changed the interface to create a hook and a trampoline function in one go to prevent the detour function from being called before the trampoline function is created. (reported by xliqz)
    • Shortened the function names from MinHook_* to MH_* to make them handier.
  • v1.0 - 22 Nov 2009

    • Initial release.
