New version of WinI2C/DDC library is available for downloading. Below are main changes made in v3.40:

• Added Windows Vista I2C/DDC API support. Now WinI2C/DDC can use this API if it cannot use other ways for communication with video chip, or if OPT_PREFER_VISTAAPI was set.
• Improved compatibility with latest nVidia and ATI video chips.
• Fixed minor problem related to communication with the driver on x64 systems.
