The news:


- Core tools
  - "chicken-install"
    - Added option "-override", which allows storing extension-
      versions in a file - this may be useful to ensure specific 
      versions of a complete set of eggs to be installed
    - Added option "-keep-installed"/"-x" that only installs explicitly
      named extensions given on the command line, if they are not
      already installed
    - Added option "-list" that lists extensions available remotely
    - Added option "-csi" to specify what interpreter should be used
      to execute the setup-script of an installed extension
    - Added option "-scan" that scans a local directory for the highest
      available extension versions available
    - Added option "-reinstall" that reinstalls all currently installed
      eggs, keeping their versions, if possible
    - Fixed bug with "chicken-install -test" when multiple extensions where
      given on the command line (thanks to Kon Lovett)
  - "chicken-status"
    - Added option "-list" that dumps versions of installed extensions
      in a format suitable for "chicken-install -override ..."
  - "csc"
    - The environment-variables "CHICKEN_C_INCLUDE_PATH" and
      "CHICKEN_C_LIBRARY_PATH" can now be used to add default include-
      and link-directories to C-compiler invocations
  - "csi"
    - ",m" now properly switches between modules (thanks to Christian 
Kellermann)

- Module system
  - Added "interfaces", named groups of exports
  - Added "functors", which are parameterized modules
  - Modules can now be aliased
  - New syntax:
    (define-interface NAME EXPORTS)
    (functor (NAME ...) EXPORTS ...)
  - Extended syntax of "module" for aliasing and functor-instantiation

- Core libraries
  - Cleaned up set of available internal SRFI-feature-identifiers
  - Fixed bugs in "make-pathname" and "normalize-pathname" (thanks to Jim 
Ursetto)
  - The reader is now more consistent when parsing symbol- and keyword names 
    that are fully or partially escaped (thanks to Kon Lovett)
  - The printer now does a better job at escaping certain single-character
    symbol names
  - Unit "lolevel"
    - deprecated "null-pointer" and "null-pointer?"
  - Fixed a bug in the Windows implementation of "file-type" (thanks to
    Jim Ursetto)
  - Fixed a bug in the implementation of "current-milliseconds" that could
    result in integer-overflow
  - Fixed an incorrect type-check in "list-ref" (thanks to Sven Hartrumpf)
  - Disabled "-setup-mode" when compiling extensions for deployment (thanks
    to Ivan Raikov)
  - Got rid of some warnings in the C runtime system that were triggered on
    the SunPro C compiler (thanks to Joe Python)
  - Fixed bug in "string->number" that caused out-of-range characters to
    be accepted for base > 10 (thanks to Jim Ursetto)

- Syntax expander
  - Fixed a bug that caused imported identifiers to leak into the 
    macroexpansion/compile-time environment (reported by Christian Kellermann)
  - Fixed a bug in the processing of extended lambda-lists (thanks to Peter Bex)
  - Peter Bex fixed a bug that caused bound variables to be incorrectly
    renamed in quoted literals (thanks to Matthew Flatt)

- Compiler
  - Fixed bug in handling of symbols in constant-definitions (thanks to Peter
    Bex)
  - Stricter check for value-part of constant definition (thanks to Kon Lovett)
  - Fixed bug that caused argument-signatures of external definitions to be
    incorrectly modified during optimization (thanks to Peter Bex)
  - Failing constant-folding expressions now produce a compile-time warning
  - Fixed various bugs in the internal type-database (thanks to Kon Lovett and
    Peter Bex)
  - Fixed incorrect optimization rules for some fp-rounding and fixnum operators

- Foreign function interface
  - "int32" was not properly detected as a valid foreign type (thanks
    to Jim Ursetto)

- Build system
  - The default target library name for an installation configured for cross-
    compilation is now "libchicken" and independent on any particular 
    setting of PROGRAM_PREFIX/PROGRAM_SUFFIX (thanks to Otavio Salvador)
