+ 4.5.1
+ 
+ - added `install-target' and `install-dev' makefile target for
+   installing only target system libraries in cross-mode and
+   development files (static libraries and headers)
+ - added `[-]no-procedure-checks-for-toplevel-bindings' compiler
+   option and declaration
+ - usage of unimported syntax in modules gives more usable
+   error messages; in particular, used but unimported FFI forms are 
+   now detected
+ - invalid syntactic forms (mostly `()') encountered by the compiler
+   or interpreter show the contextual form containing the expression,
+   or, if indicated by the context warns about missing imports
+ - simplified manual pages of all core tools - they now refer to
+   the output shown by invoking `<tool> -help'
+ - added new option `-feature FEATURE' to `chicken-install' tool
+   to pass feature-identifiers to invocations of `csc'
+ - removed deprecated `-host-extension' option from `chicken-install'
+ - `chicken-status' in a system built for cross-compilation now 
+   lists extensions installed in the target prefix, unless the
+   new `-host' option is given on the command line
+ - `chicken-uninstall' in a system built for cross-compilation now 
+   removes extensions installed in the target prefix, unless the
+   new `-host' option is given on the command line
+ - added missing entry for `finite?' to the `chicken' module
+   exports
+ - added new procedure `port-closed?' to the `library' unit
+   (contributed by Peter Bex)
+ - added new procedure `symbol-append' to the library unit
+ - the compiler-option `-optimize-level 0' is equivalent to
+   `-no-compiler-syntax -no-usual-integrations`
+ - internal rewritings of `map' and `for-each' ensure correct
+   evaluation order of the arguments and does a better job
+   at detecting non-list arguments (thanks to Jim Ursetto)
+ - `void' now takes arbitrary arguments and ignores them
+ - deprecated `noop' (from the `data-structures' unit) which
+   is now replaced by `void'
+ - the `time' macro now performs a major garbage collection
+   before executing the contained expressions and writes
+   the timings in a more compact format to the port given
+   by `(current-error-port)' instead of the standard output
+   port
+ - definitions of the form `(define define ...)' and
+   `(define-syntax define-syntax ...)' now trigger an error,
+   as required by R5RS (thanks to Jeronimo Pellegrini and Alex
+   Shinn)
+ - deprecated `random-seed' from the `extras' unit, since it
+   is identical to `randomize'
+ - added new procedure `create-temporary-directory' to the
+   `files' unit
+ - deprecated the optional path separator argument to
+   `make-pathname'
+ - slightly improved the performance of keyword argument
+   processing
+ - the second argument to `find-files' from the `posix' unit
+   is now optional and defaults to `(constantly #t)'
+ - removed the deprecated `canonical-path' and `current-environment'
+   procedures from the `posix' unit
+ - warnings that mostly refer to programming style issues are
+   now coined `notes' and are only shown in the interpreter
+   or when debug-mode is enabled or when scrutiny is enabled
+   when compiling
