* Added a helper function ```MH_CreateHookApi```. (Thanks to uniskz).
* Fixed a false memory leak reported by some tools.
* Fixed a degradated compatibility issue.
- **v1.3 - 13 Sep 2014**
* No major changes from v1.3-beta3.
- **v1.3-beta3 - 31 Jul 2014**
* Fixed some small bugs.
* Improved the memory management.
- **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](https://github.com/jarredholman/minhook)).
* Fixed a small bug in the GetRelativeBranchDestination function ([pillbug99](http://www.codeproject.com/Messages/4058892/Small-Bug-Found.aspx)).
* 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](http://www.codeproject.com/Messages/4578613/Re-Bug-LoadLibraryExW-hook-fails-on-windows-2008-r.aspx)).
- **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](http://www.codeproject.com/Messages/3280374/Unsafe.aspx))
* Shortened the function names from ```MinHook_*``` to ```MH_*``` to make them handier.
- **v1.0 - 22 Nov 2009**
* Initial release.
