Over on the tech. support web site we have posted a bulletin regarding issues that have been found with PI ACE 2010 R2 that could intermittently impact calculation results
A review has been completed, issues identified and we are verifying one last item, prior to starting testing for PI ACE 2010 R2 SP1
PI ACE 2010 R2 SP1 will be a full release of PI ACE 2010 R2 including fixes for the issues discussed in the bulletin and additional items. Once PI ACE 2010 R2 SP1 is available we'll retire PI ACE 2010 R2
The product roadmap now includes an entry for PI ACE 2010 R2 SP1 and is the official location to see planned/release information.
That said as this blog is being written we are targeting July 2011 for SP1
