• OpenSolaris based upon builds snv_48 through snv_104

x86 Platform

• Thunderbird 2.0 (for Solaris 10) without patch 125542-04
  
• OpenSolaris based upon builds snv_48 through snv_104

OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows:

$ uname -v
snv_101
