Mesa 20.2.1 Release Notes / 2020-10-14
|
||||
======================================
|
||||
|
||||
Mesa 20.2.1 is a bug fix release which fixes bugs found since the 20.2.0 release.
|
||||
|
||||
Mesa 20.2.1 implements the OpenGL 4.6 API, but the version reported by
|
||||
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
|
||||
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
|
||||
Some drivers don't support all the features required in OpenGL 4.6. OpenGL
|
||||
4.6 is **only** available if requested at context creation.
|
||||
Compatibility contexts may report a lower version depending on each driver.
|
||||
|
||||
Mesa 20.2.1 implements the Vulkan 1.2 API, but the version reported by
|
||||
the apiVersion property of the VkPhysicalDeviceProperties struct
|
||||
depends on the particular driver being used.
|
||||

||||
