Intel graphics driver releases tend to be a lot less exciting than their Nvidia and AMD counterparts, but they're just as important for those who are currently using a system without a discrete graphics card.
The latest 18.104.22.16879 Intel graphics drivers introduce support for the company's HD Graphics 500 series GPUs, which are integrated into their new Skylake processors. There is also official support for OpenGL 4.4 in these new drivers, provided you have either a Skylake or Broadwell CPU.
As for bug fixes, Intel has addressed an issue where displays connected through DisplayPort 1.2 flicker after returning from sleep. There are also fixes for graphics corruption in some Windows Store video apps, and crashes in EVE Online and World of Warcraft.
