From: Matthew Flatt <mflatt@cs.utah.edu> To: plt-scheme@list.cs.brown.edu Subject: [plt-scheme] 301.5 Date: Mon, 6 Feb 2006 10:29:14 -0700 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.
