RMAExpress 1.0 beta 4 has been released. It can be downloaded at: http://rmaexpress.bmbolstad.com Changes since 1.0 beta 3 - Support for reading AGCC/Generic format CEL files - Significant restructuring of the CEL file parsing code - Significant source code changes to improve portability Please note that the binary release for Windows operating systems has been built in a different way than used for previous versions. In particular, this version was built using Microsoft Visual C++ Express Edition natively on Windows, rather than cross-building on my Linux machine using mingw. I have not had a chance to check all possible workflows for this build, but I expect few problems. Of most significant note is that this build should support usage on Microsoft Windows Vista. The 0.5 release version remains the stable version while the 1.0 beta X series are developmental releases.
