VMware Workstation 6.5.1 has just been released, so start your engines and download:

With this release of VMware Workstation, the following new features and support have been added:

• Japanese localization — A localized version of Workstation is now available in Japanese for Windows hosts.
  Note: Technical Support services for Workstation are currently delivered in English. Japanese-speaking support engineers are available in a limited capacity during the operating hours of the local support center. For more information, see VMware local language support.
• Smart card support for Linux guests — Smart cards are now experimentally supported with Linux guests.
• Unity mode on Linux guests — Although support for Unity mode on Linux guests is still experimental, repainting of application windows is much improved.
• 3-D graphics — Additional improvements have been made to improve 3-D performance on Windows XP guests.

I will be testing Unity Mode on Ubuntu tonight, so expect a couple screenshots to appear! The full release notes can be found here.
