Latest Mac OS X upgrade from Apple

I loaded this, relatively small (14 MB), update last night to no ill effects. I haven't noticed any cosmetic changes, either.

The 10.3.6 Update delivers enhanced functionality and improved reliability for Mac OS X v10.3 "Panther" and is recommended for all users.

Key enhancements include:

• improved file sharing for Mac (AFP), UNIX (NFS) and PC (SMB/CIFS) networks
  
• more reliable network automounts and launch of network applications
  
• improved OpenGL technology and updated ATI and NVIDIA graphic drivers
  
• additional FireWire audio and USB device compatibility
  
• updated Calculator, DVD Player, Image Capture, and Safari applications
  
• improved compatibility for third party applications
  
• previous standalone security updates
