The newest feature addition for Mesa 25.3 is enabling support 8x multi-sample anti-aliasing (MSAA) within the LLVMpipe software rasterizer.
While LLVMpipe has a tough enough time handling demanding OpenGL workloads with CPU-based rendering workloads, for lightweight OpenGL tasks where anti-aliasing may be desired, 8x MSAA is now supported.
Up to this point the LLVMpipe software driver has only handled up to 4x MSAA while for Mesa 25.3 is now 8x MSAA. Michał Król of Broadcom worked out this 8x MSAA support for LLVMpipe.
