SeDuMi is a great piece of software for optimization over symmetric cones. It was developed by Jos F. Sturm, who passed away in 2003. Following some months of uncertainty the Advanced Optimization Lab at McMaster University continued the development and maintenance of SeDuMi for a while. The developers were Oleksandr Romanko and Imre Pólik, both were PhD students of Dr. Tamás Terlaky. Currently SeDuMi is hosted and maintained by CORAL Lab at the Department of Industrial and Systems Engineering at Lehigh University.

Current versions can be found in the Downloads section of this website. The Downloads section currently contains the latest release by Jos, i.e. version 1.05 R5. The latest modification is from 2003, but the core code has not changed much since 2001. The complete list of changes since 1998 is in the Version history  section.
