Another biweekly development release is here with Wine 11.21 out now bringing various improvements for running Windows apps and games on Linux.

Key Changes

• Better WoW64 OpenGL performance with map_buffer_client_pointer extension.
• Initial version of the Voice Capture DSP library.
• Improved support for user accounts.
• Various bug fixes.

For the WoW64 update - this should help some older 32-bit Windows games that use OpenGL run a bit better through Wine, by cutting down on some unnecessary work behind the scenes. It could mean smoother gameplay and better performance, as long as your graphics driver supports it.
