Today , Telligent Release CommunityServer 2008.5 SP2 . The bug fix is major patch for this ServicePack . And no new function in this SP.
A important change , If you used MSSQL 2000 for CS2008.5. You will not upgrade CS2008.5 SP2 SQLScript part , because it's used MSSQL 2005 command for best performance. But you still can use CS2008.5 SP2 Binary files for security issue and fix bug. ( I think CS2009 will not work MSSQL 2000 platform )
Detail fix list include in Read_me.txt of ServicePack .
