| Mesa 18.2.0 Release Notes / September 7, 2018
 | |
| =============================================
 | |
| 
 | |
| Mesa 18.2.0 is a new development release. People who are concerned with
 | |
| stability and reliability should stick with a previous release or wait
 | |
| for Mesa 18.2.1.
 | |
| 
 | |
| Mesa 18.2.0 implements the OpenGL 4.5 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
 | |
| 4.5. OpenGL 4.5 is **only** available if requested at context creation.
 | |
| Compatibility contexts may report a lower version depending on each
 | |
| driver.
 | |
| 
 | |
| libwayland-egl is now distributed by Wayland (since 1.15, `see
 | |
| announcement <https://lists.freedesktop.org/archives/wayland-devel/2018-April/037767.html>`__),
 | |
| and has been removed from Mesa in this release. Make sure you're using
 | |
| an up-to-date version of Wayland to keep the functionality.
