18.3.0 Release Notes / TBD
</h1>
20 Mesa
18.3.0 is a new development release. People who are concerned
21 with stability and reliability should stick with a previous release or
25 Mesa
18.3.0 implements the OpenGL
4.5 API, but the version reported by
26 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
27 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
28 Some drivers don't support all the features required in OpenGL
4.5. OpenGL
29 4.5 is
<strong>only
</strong> available if requested at context creation.
30 Compatibility contexts may report a lower version depending on each driver.
34 libwayland-egl is now distributed by Wayland (since
1.15,
35 <a href=
"https://lists.freedesktop.org/archives/wayland-devel/2018-April/037767.html">see announcement
</a>),
36 and has been removed from Mesa in this release. Make sure you're using
37 an up-to-date version of Wayland to keep the functionality.
