+
+	From: pegelow@moorea.uni-muenster.de (Ulrich Pegelow)
+	* mbe.scm (hyg:tag-do): Scoping was wrong.  The region of binding

+	<test> expression, instead it incorrectly included the <init>
+	expression. (rf. R4RS, 4.2.4)
+	(hyg:tag-lambda): the body of a lambda expression should be
+	generated using hyg:tag-generic instead of hyg:tag-vanilla. This
+	allows expressions within lambda to behave hygienically.

+
+	From: lutzeb@cs.tu-berlin.de (Dirk Lutzebaeck)
+	* format.scm slib.texi: Format 3.0.
+  * format's configuration is rearranged to fit only into SLIB. All
+    implementation dependent configurations are done in the SLIB init files
+  * format's output routines rely on call-with-output-string now if 
+    output to a string is desired
+  * The floating point formatting code (formatfl.scm) moved into
+    format.scm so that there is only one source code file; this
+    eliminates the configuration of the load path for the former
+    formatfl.scm and the unspecified scope of the load primitive
+  * floating point formatting doesn't use any floating point operation or
+    procedure except number->string now; all formatting is now based
+    solely on string, character and integer manipulations
+  * major rewrite of the floating point formatting code; use global
+    buffers now  
+  * ~f,~e,~g, ~$ may use also number strings as an argument
+  * ~r, ~:r, ~@r, ~:@r roman numeral, and ordinal and cardinal
+    English number printing added (from dorai@cs.rice.edu)
+  * ~a has now a working `colinc' parameter
+  * ~t tabulate directive implemented
+  * ~/ gives a tabulator character now (was ~T in version < 2.4)
+  * ~& fresh line directive implemented
+  * ~@d, ~@b, ~@o and ~@x now has the CL meaning (plus sign printed)
+    automatic prefixing of radix representation is removed
+  * ~i prints complex numbers as ~f~@fi with passed parameters
+  * ~:c prints control characters like emacs (eg. ^C) and 8bit characters
+    as an octal number

+    forced (see format:iobj-case-conv format.scm)

+    if available by the implementation
+  * format now accepts a number as a destination port; the output
+    is then always directed to the current error port if available by
+    the implementation
+  * if format's destination is a string it is regarded as a format string now
+    and output is the current output port; this is a contribution to
+    Scheme->C to use format with the runtime system; the former semantics
+    to append tothe destination string is given up

+  * tested with scm4d, Elk 2.2, MIT Scheme 7.1, Scheme->C 01Nov91
