    Gauche 0.8.3: Bug fix release

    It turned out that 0.8.2's source-code encoding detection feature had a
    bug; if you're using Windows-style (CRLF) line-separator, the coding-aware
    port repeats one character at the beginning of the second line. It doesn't
    do any harm if first few lines of your code are comments, but it's annoying
    when you stumbled on it, so I decided to release a fixed version.

    This release also includes a couple of improvements: The coding-aware ports
    recognizes Emacs-style coding name (e.g. euc-jp-unix) and just ignores the
    Emacs-specific suffix (e.g. -unix). And external representations of
    f32vector and f64vector are now accurate.

    Gauche 0.8.2: Major revision of infrastructure.

     * New features
         - A condition (exception) system a la srfi-35 and (part of) srfi-36
            is supported. Used with guard (srfi-34), now it is possible to
            handle exceptions in more comprehensive way. See the \ 
"Exception"
            section of the manual, which has been rewritten accordingly.
         - Source-code encoding detection. Now Gauche recognizes a special
            comment like "coding: utf-8" near the beginning of the \ 
source file,
            and use appropriate conversion to load the source file. See
            "Multibyte Script" section of the manual for the details. This
            feature alone can be used independently from loading programs, via
            coding-aware ports, so the programs that processes Scheme scripts
            can also recognize the special comments.
         - Virtual ports are supported. Virtual ports are the ports whose
            behavior can be customized in Scheme. See the description of
            gauche.vport module in the manual for the details.
     * Improvements
         - Updated GC to Boehm GC 6.3. It fixes some GC-related problems on
            64bit architectures.
         - gauche.fcntl: F_GETOWN and F_SETOWN are supported, if the system
            provides them.
         - gauche.termios: c_cc field of struct termios is now accessible from
            Scheme. (Thanks to Kogule Ryo).
         - gauche.uvector: Added string->s8vector! and string->s8vector!.
            TAGvector-copy!'s API is changed so that it matches with srfi-13's
            string-copy! and srfi-43's vector-copy!.
         - Port implementation is cleaned up. Now line count is available not
            only for file ports but any ports (as far as it's doing character I
            /O). byte-ready? is added for binary I/O polling.
         - text.csv: quote character is customizable.
     * Bug fixes
         - INCOMPATIBLE CHANGE: The previous version's rfc.mime's API was
            broken. It couldn't handle MIME part whose message was non-encoded
            binary. Now MIME part stream parser is re-implemented using virtual
            ports, and the reader argument passed to the MIME part handler is
            dropped. www.cgi is also affected if you're using customized
            handler for file uploads. See the reference manual for the new API.
         - SONAME of the library is now set, if the platform supports it.
         - gauche.array: Some functions were not exported, although they were
            mentioned in the manual.
         - gauche.charconv: Fixed a bug in converting 2nd plane of JIS.
         - gauche.regexp: regexp-replace-all looped infinitely for some
            patterns. Now it raises an error.
         - dbm.fsdbm: It couldn't store binary data.
         - rfc.822: rfc822-parse-date returned wrong month number (off by
            one).
         - util.match: Fixed a bug in quasipattern. The description of
            quasipatterns in the reference manual is also revised to explain it
            better.
         - srfi-19: date->julian-day didn't recognize tz-offset.
         - Some bugs in numeric code are fixed.
         - let-args had a bug in parameter handling of 'else' clause.
         - directory-list: when :filter-add-path? is true, there was a bug
            that "." and ".." were included in the results \ 
even :children?
            argument was true.
         - There was a bug that causes an infinite loop during class
            redefinition.
         - let-keywords*: fixed a bug that corrupts expansion when used in
            r5rs macro.
     * C API Change
         - Class initialization API is overhauled. Scm_InitBuiltinClass is
            obsoleted; use Scm_InitStaticClass instead.
         - Port structure is changed quite a bit.
         - Functions to convert Scheme integers to C integers are revised, to
            handle out-of-range error in more flexible way.
         - API of Scm_Load, Scm_LoadFromPort and related functions are changed
            to support more flags.
