Proposed last year was [1]GL_EXT_mesh_shader as a cross-vendor mesh shading extension . That OpenGL mesh shader work led by an AMD engineer was merged today into the OpenGL Registry.

That GL_EXT_mesh_shader support was worked on the past year in tandem with [2]mesh shader support for the RadeonSI Gallium3D driver and landing the necessary prerequisites upstream in Mesa. There's also been [3]Zink driver work on OpenGL mesh shader support too .

This OpenGL mesh shader support was motivated in part by the Nvidium project as a rendering engine for Sodium with Minecraft Java Edition have been interested in seeing OpenGL mesh shader support work outside the confines of NVIDIA's vendor extension for it (GL_NV_mesh_shader).

As of a short time ago, the GL_EXT_mesh_shader support was [4]merged to the OpenGL Registry. Now that it's official, hopefully the remaining bits of the Mesa driver support will be merged soon.

Valve open-source graphics Mesa developer Mike Blumenkrantz has also [5]blogged with some additional commentary on this exciting milestone for OpenGL in 2025.
