## Changes Introduced in V8.1.0

The following describes the most significant changes which occurred in the AST library between versions V8.0.5 and V8.1.0:

1. The configure script has a new option “–without-fortran” that allows AST to be built in situations where no Fortran compiler is available. The resulting library has no Fortran interface and so cannot be used within Fortran applications. Also, the link scripts do not attempt to include the fortran runtime libraries.
