Changes to Dynalign source code for Unix/Linux:

September 30, 2004. Code was revised to compile on Mac OS X.

March 01, 2005. Dynalign with suboptimal structure prediction posted.

March 18, 2006. Dynalign (from RNAstructure 4.3) released. This version is accelerated compared to previous software versions.

May 02, 2007. Dynalign (from RNAstructure 4.5) released. This version is accelerated using an HMM alignment method to determine regions in the alignment space that are very unlikely and hence can be neglected. This removes the need for the user to specify an M parameter.
