As I promised several days ago, the changes to fix the known bugs in
the GNU Emacs/Scheme interface are now available.  These changes
upgrade the two current releases, 6.1.1 and 6.2.1, to 6.1.2 and 6.2.2
respectively.  Note: if you do not use the Emacs/Scheme interface,
there is no difference between the old and new versions of Scheme.

6.1.2 is the current released version of MIT C Scheme.

6.2.2 is the beta test version which accompanies the Liar compiler;
this version is distributed for use on Sun 3 and HP 9000 series 300
workstations only.

The patches can be obtained as follows:

----------------------------------------------------------------------
6.1.1 -> 6.1.2 upgrade:

Via anonymous ftp from "zurich.ai.mit.edu": look for one of these
files:

    pub/scheme/patch.shar-6.1.1-6.1.2
    pub/scheme/patch.tar-6.1.1-6.1.2
    pub/scheme/patch.tar-6.1.1-6.1.2.Z

Or send mail to "bug-cscheme@zurich.ai.mit.edu" requesting to have the
patches sent to you by EMAIL.

----------------------------------------------------------------------
6.2.1 -> 6.2.2 upgrade:

Via anonymous ftp from "zurich.ai.mit.edu": look for one of these
files:

    pub/liar/patch.shar-6.2.1-6.2.2
    pub/liar/patch.tar-6.2.1-6.2.2
    pub/liar/patch.tar-6.2.1-6.2.2.Z

These patches are not available by EMAIL; since you must have gotten
this version of Scheme via FTP (we don't distribute it any other way).

----------------------------------------------------------------------
These patches are also available from "prep.ai.mit.edu".

Each patch consists of a set of replacement files for the previous
version.  The files should be read into the directory of the previous
version and Scheme should be rebuilt.  Pay attention to the following
details:

* The file "etc/xscheme.el" must be installed in the GNU Emacs "lisp/"
subdirectory.  Always use the version of this file that is distributed
with Scheme; the version distributed with Emacs is not guaranteed to
be correct for the version of Scheme that you have.  Don't forget to
byte compile the file if necessary.

* Some ".psb" files are distributed; these must be converted to ".bin"
files using the program "microcode/Psbtobin" which is included with
the original release of Scheme.
