It appears that Esri has released ArcGIS 10.0 Service Pack 4 today.

• ArcGIS 10 (Desktop, Engine, Server) Service Pack 4
• ArcIMS 10 Service Pack 4
• ArcSDE 10 Service Pack 4

I looked at the issues fixed list and didn’t see anything that was critical. I do feel for the guys that ran into this problem.

NIM033250 – The GPS Toolbar does not recognize over 9 COM ports.

The Esri delivery guy is busy today getting SP4 out.
