MzScheme and MrEd are now version 301.5 in the SVN repository trunk.

The changes are all internal improvements:

 * For nested captured continuations, the shared continuation tail is
   now represented by shared data (instead of separate copies for each
   continuation).

 * JIT: generates faster calls to `letrec’-bound procedures; inlines
   more arithmetic and common type tests.

 * MrEd: regions work correctly and consistently with auto-scrolled
   canvases.
