| 4 | Mesa 20.2.1 is a bug fix release which fixes bugs found since the 20.2.0 release.
|
|---|
| 5 |
|
|---|
| 6 | Mesa 20.2.1 implements the OpenGL 4.6 API, but the version reported by
|
|---|
| 7 | glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
|
|---|
| 8 | glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
|
|---|
| 9 | Some drivers don't support all the features required in OpenGL 4.6. OpenGL
|
|---|
| 10 | 4.6 is **only** available if requested at context creation.
|
|---|
| 11 | Compatibility contexts may report a lower version depending on each driver.
|
|---|
| 12 |
|
|---|
| 13 | Mesa 20.2.1 implements the Vulkan 1.2 API, but the version reported by
|
|---|
| 14 | the apiVersion property of the VkPhysicalDeviceProperties struct
|
|---|
| 15 | depends on the particular driver being used.
