Please note: This file provides a summary of significant changes
between versions and sub-versions of Perl, not a complete list
of each modification.  If you'd like more detailed information,
please consult the comments in the patches on which the relevant
release of Perl is based.  (Patches can be found on any CPAN
site, in the .../src/5.0 directory for full version releases,
or in the .../src/5/0/unsupported directory for sub-version
releases.)

----------------
Version 5.003_04
----------------

This patch was primarily to fix bugs and to clean up some of
the changes made in 5.003_03.  The details are described below.
A very brief summary is:

o Visible Changes to Core Functionality

   -Allow and document permissions for FileHandle::new and
    IO::File::new.
   -glob in Safe compartment used to allow shell access; now
    it's in the same category as `` and system().

o Configure and build enhancements
   
   -perl library name is again -lperl, not -lperl5 in some cases.
   -Several hint files no longer set -g -DDEBUGGING by default.
    Instead, they just turn off optimization, since that is
    probably what was intended.
   -Include OS/2 and Plan9 updates.

o Bug fixes

   -SEGV with $_[0] and circular references fixed.
   -Ilya's debugger patch.
   -FAKE typeglobs fixed.
   -truncate with file name now works.
   -lval substr() no longer coredumps with refs
   -lval substr now clears lexicals in re-entered scopes.
   -core dump in caller() for signal handler for __DIE__.

o Specific Changes

Here are the specific file-by-file changes.

Index: Changes

    Updated for 5.003_04.

Index: Configure

    Change name of shared libperl library back to libperl.so.xxx,
    so that a simple -lperl picks up either libperl.a or
    libperl.so.xxx.

    Check if $sh='' in case we've reloaded an old config.sh

Index: INSTALL

    Change name of shared perl library to libperl, instead of
    libperl5.

    Add notes about fragility of shared libperl and the usefulness
    of archlib to separate different binaries.

Index: MANIFEST

    os2/notes removed

    obsolete hints/dnix.sh removed.

    New typeglob test.

Index: Makefile.SH

    For building shared libperl, relocate whole rule to
    inside the if test -f $osname/Makefile.SHs case.

Index: Porting/Glossary

    Updated.

Index: README.os2

    Updated.

Index: av.c

    Subject: Re: SEGV with $_[0] and circular references

    Subject: random cleanup

    This patch removes a few obvious redundancies in the source.

Index: config_H

    Updated.  Note new comments to make AIX happy.

Index: config_h.SH

    Change /*#define../**/ into /*#define../ **/
    to make IBM's xlc compiler shut up about nested comments.
    The /*#define FOO /**/ is a perfectly legal un-nested comment, and
    I wish IBM would fix it's blasted compiler instead.  In the meantime
    we'll take mercy on the poor AIX user and get rid of the screenfulls
    of stupid warning messages.  Thanks to Hallvard B Furuseth
    <h.b.furuseth@usit.uio.no> for the fix.

Index: dump.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: ext/FileHandle/FileHandle.pm

    This patch documents the behavior of FileHandle::{new,open} with
    regard to open modes.  It also documents the exportation of Fcntl
    constants.

    This patch fixes a bug observed by Tom Christiansen: FileHandle::new
    didn't allow for file permissions after the file mode.  Here's a patch.

Index: ext/IO/lib/IO/File.pm

    This patch fixes a bug observed by Tom Christiansen: IO::File::new
    didn't allow for file permissions after the file mode.  Here's a patch.

    This patch documents the behavior of IO::File::{new,open} with
    regard to open modes.  It also documents the exportation of Fcntl
    constants.

Index: ext/Opcode/Opcode.pm

    Subject: Re: glob in Safe compartment allows shell access

    I've moved the glob op into the same opcode tag as backticks and system
    and added a comment.

Index: gv.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: handy.h

    Subject: Patch for LONG_MAX & co.

    Sorry about adding yet another #ifdef forest, but hopefully this
    should resolve the *_MAX issues permanently. It adds to the
    previously defined PERL_LONG_MAX, PERL_LONG_MIN, and PERL_ULONG_MAX
    symbols the complete set of
    /PERL_U?(CHAR|SHORT|INT|LONG)_(MAX|MIN)/, and installs aliases to
    those from /(I|U)(8|16|32|V)_(MAX|MIN)/ so that for any standard
    Perl typedef, like I32 or UV, you can reference I32_MAX or UV_MIN,
    and get appropriate figures. All references to LONG_(MIN|MAX) are
    changed appropriately.

    The .c changes have the side effect of making cast_uv properly use quad
    limits if quads are in use, but longs aren't 64 bit. Hopefully this all
    works, but I don't have any handy Crays to try it out on.

    Add notes on perl's internal types, specifically Quad_t and IV.

Index: hints/hpux.sh

    Remove the d_bsdpgrp hint.  The defaults should be ok.

Index: hints/irix_6_2.sh

    Change optimize=-g to optimize=none to avoid pulling in -DDEBUGGING,
    unless that's what the user really wants.

Index: hints/mpeix.sh

    Change optimize=-g to optimize=none to avoid pulling in -DDEBUGGING,
    unless that's what the user really wants.

Index: hints/os2.sh

    Fixes for sh vs. bin_sh + cleanup.

Index: hints/ultrix_4.sh

    Don't call optimize=-g, just call optimize=none.  The -g
    pulls in -DDEBUGGING, which might not be wanted.

Index: lib/ExtUtils/MM_Unix.pm

    .C$(obj_ext) removed under OS/2 - conflicts with .c$(obj_ext).

Index: lib/ExtUtils/xsubpp

    Fix SCOPE?  (See pod/perlxs.pod).
    Up version number to 1.938.

Index: lib/Test/Harness.pm

    Add a return value to runtests - non-zero if all tests ran ok,
    zero otherwise.

Index: lib/perl5db.pl

    Ilya's debugger patch.
        Undefined subroutine &Carp::longmess called at
            /opt/perl5.003_03/lib/perl5db.pl line 1423.


    Make perl5db compatible with the recent 'strict refs' enforcement
    in %SIG.

Index: malloc.c

    A patch to perl5.003_02/malloc to give a sensible error abort() message
    in ANSI C, and to give it to stderr instead of stdout.

    Use config_h's STRINGIFY macro instead of pre-ANSI "p".

Index: mg.c

    Subject: FAKE typeglobs seriously busted (with patch)

    Handling of fake typeglobs (scalars that are really globs
    in disguise) is seriously busted since 5.002 (it wasn't
    so in 5.001n).
    The problem is that mg_get() on a glob calls gv_efullname()
    which might coerce its first arg to a string.

    Sub-critical patch to conceivably fix some %SIG problems. (Shared hash key
    weren't being properly detected by some of the sig magic, but as shared
    hash keys wouldn't normally be used in %SIG it's unlikely this is a
    significant problem.)

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: myconfig

    Update perlio-related variables.

Index: op.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: opcode.h

    Updated.  See opcode.pl.

Index: opcode.pl

    Subject: Re: truncate with file name does not work (with patch)

    The prototype for truncate was changed so that perl won't die
    with C<use strict;> when the first arg is a bareword (filehandle).
    I think it was Tom (as in "tchrist") who brought this up.

    Here's a patch that undoes the damage, makes it work with
    C<use strict;>, and adds to the testsuite.

Index: os2/Makefile.SHs

    perllib vs. LIBPERL

Index: os2/diff.configure

    Updated.

Index: os2/os2.c

    SH_PATH_INI vs. BIN_SH

Index: os2/os2ish.h

    SH_PATH_INI added (needed to redefine SH_PATH for binary
            distribution).
    SH_PATH is redefined.

Index: patchlevel.h

    SUBVERSION 4.

Index: perl.h

    Subject: Patch for LONG_MAX & co.

    Sorry about adding yet another #ifdef forest, but hopefully this
    should resolve the *_MAX issues permanently. It adds to the
    previously defined PERL_LONG_MAX, PERL_LONG_MIN, and PERL_ULONG_MAX
    symbols the complete set of
    /PERL_U?(CHAR|SHORT|INT|LONG)_(MAX|MIN)/, and installs aliases to
    those from /(I|U)(8|16|32|V)_(MAX|MIN)/ so that for any standard
    Perl typedef, like I32 or UV, you can reference I32_MAX or UV_MIN,
    and get appropriate figures. All references to LONG_(MIN|MAX) are
    changed appropriately.

    limits if quads are in use, but longs aren't 64 bit. Hopefully this all
    works, but I don't have any handy Crays to try it out on.

    Add notes on perl's internal types, specifically Quad_t and IV.

Index: perlio.c

    Removes an incorrect prototype for setlinebuf from
    perlio.c because it conflicts with the correct declaration in
    MachTen's stdio.h (and possibly other stdio's as well).

    Secondly, the code in perlio.c is not handling the (!PERLIO_IS_STDIO &
    HAS_F[GS]ETPOS) case.  The patch fixes this omission (in a rather lumpen
    manner).  I don't think this should affect platforms which try to hack a
    different path through the #ifdef forest, but this assertion would benefit
    from testing...

Index: plan9/config.plan9

    Updated.

Index: plan9/fndvers

    Updated.

Index: plan9/mkfile

    Updated.

Index: plan9/setup.rc

    Updated.

Index: pod/perldiag.pod

    Subject: lval substr() coredumps with refs (with patch)

    substr() coredumps with a target that is a ref, when it is used in
    an lvalue context.
    The patch below corrects the problem by stringifying the reference
    first (and emitting a warning when appropriate).

Index: pod/perlxs.pod

    document xsubpp SCOPE:

Index: pp.c

    Subject: lval substr() fails to clear lexicals in re-entered scopes (with patch)

    substr() in lvalue context interacts in buggy fashion with SVs that
    are !SvOK.  This manifests itself with lexicals that have a REFCNT of
    1, since these are merely "cleared in place" by setting SvOK_off.

    Subject: lval substr() coredumps with refs (with patch)

    substr() coredumps with a target that is a ref, when it is used in
    an lvalue context.
    The patch below corrects the problem by stringifying the reference
    first (and emitting a warning when appropriate).

    Subject: Patch for LONG_MAX & co.

Index: pp_ctl.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: pp_hot.c

    Subject: Patch for LONG_MAX & co.

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: pp_sys.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: proto.h

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: run.c

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

Index: sv.c

    Subject: random cleanup

    This patch removes a few obvious redundancies in the source.

    Subject: sv_setsv patch

    This patch changes neither behavior nor performance.  However, it does
    reduce code size and improve maintainability by combining some common
    code in gv_fullname() and gv_efullname().

    From: Chip Salzenberg <salzench@nielsenmedia.com>
    Subject: Track SVs for destruction when -DPURIFY

    When checking for memory leaks, I compiled Perl with "-DPURIFY".
    Although that flag improves the leak checking, it also breaks
    destruction of global objects, because SVs aren't kept in captive
    arenas any more.

    This patch rectifies the problem by providing an alternative
    method for keeping track of SVs when Perl is compiled for Purify.
    It has no effect on normal operation.


    Add comment about assert(len >=0) when len is unsigned anyway.

Index: t/io/fs.t

    Subject: Re: truncate with file name does not work (with patch)

    The prototype for truncate was changed so that perl won't die
    with C<use strict;> when the first arg is a bareword (filehandle).
    I think it was Tom (as in "tchrist") who brought this up.

    Here's a patch that undoes the damage, makes it work with
    C<use strict;>, and adds to the testsuite.

    The "not implemented" branch is missing a "\n".

Index: t/op/gv.t

    Subject: FAKE typeglobs seriously busted (with patch)

    Handling of fake typeglobs (scalars that are really globs
    in disguise) is seriously busted since 5.002 (it wasn't
    so in 5.001n).

    The problem is that mg_get() on a glob calls gv_efullname()
    which might coerce its first arg to a string.

Index: util.c

    Subject: Re: Perl 5.003 dumps core executing caller() in signal handler for
            __DIE__ (with patch)

    sv_2pv() might call croak() (which is not prepared to handle that
    when it calls sv_2pv(), itself).  Likewise for warn() (but under
    slightly more esoteric circumstances--mg_get() in sv_2pv() might
    trigger a call to warn()).


    Subject: Patch for LONG_MAX & co.

    PERL_BADLANG is examined by default before issuing a warning during
            internationalization.

Index: utils/h2xs.PL

    Make leading =head NAME item a paragraph so pod2man finds it.

Index: utils/perldoc.PL

    Use col -x to filter out half-line feeds (ESC-9) from
    HP-UX nroff -man output.  (col -x isn't portable -- SunOS
    doesn't support the -x option.)

----------------
Version 5.003_03
----------------

Most of the changes in 5.003_03 are to make the build and installation
process more robust.  The details are described below.  A very brief
summary is:

o Visible Changes to Core Functionality

   -Support for tied filehandles.

o Configure enhancements

   -How to build and install a shared libperl.so is now documented
    and supported, though it's not the default for most platforms.

o Bug fixes

   -Support bit operations on strings longer than 15 bytes.

   -If a regex supplied to split() contains paranthesized subpatterns
    that can result in null matches, perl no longer coredumps.

   -Fix problems with each() on tied hashes.

   -Make h2ph architecture-independent by using Config at run-time
    rather than extraction time.

o Specific Changes

Here are the specific file-by-file changes.

Index: Changes

        Include 5.003_03 change notes.

        Move older change notes to separate files.

Index: Changes5.000

        New file.  Changes from perl4.036 to 5.000.

Index: Changes5.001

        New file.  Changes from 5.000 to 5.001

Index: Changes5.002

        New file.  Changes from 5.001 to 5.002

Index: Changes5.003

        New file.  Changes from 5.002 to 5.003

Index: Configure

        Relaxed warning about ksh on exotic machines.

        Changed usesafe to useopcode.

        Add search for gzip and zip.

        Look more carefully for $sh (the Bourne-ish shell).
        Use that info to set $startsh correctly.

        Change prompts for PerlIO interface.  See INSTALL
        for how this is supposed to work.  The default is
        still the same as in 5.003_02, namely don't use
        any fancy new PerlIO stuff.

        Don't look for sigvec() since we don't actually use it.
        (Plus, it used to print an alarming misleading message about
        race conditions.)

        Look for stdio's _filbuf under the possible names of
        _filbuf, __filbuf, and _fill.

        New $useshrplib variable to control whether we build a shared
        libperl.so.  The name of the library is in $libperl.
        Always install it in $installarchlib/CORE/$libperl.

        Check for <sys/resource.h> and <sys/wait.h> for NetBSD.

        Replace old $altmake stuff with newer autoconf-ish
        $make_set_make, which checks if $make sets $(MAKE).  Now you
        choose an alternate make with sh Configure -Dmake=gmake (or
        whatever).

        Remove 'ln' for the list of essential commands.  Simulate
        it with 'cp' if necessary.

        Change `logname` prompts to handle extra gratuitous spaces in
        Ultrix output.

        Autodetect os2.

        Fix silly bug in checking for fully-qualified names in /etc/hosts.

        Generalize Gconvert tests.  Give correct and more useful
        error messages.

        Use $obj_ext instead of literal '.o' in the dynaloader test.

        Include appropriate header files in bcopy() and memcpy()
        tests.  Note whether memmove is available.

        Check whether struct sigaction works (needed for Solaris 2.5
        with -Xc).

        Include appropriate header files for randbits test.

Index: INSTALL

        Add note about space requirements.

        Update to match Configure changes (Opcode vs. Safe,
        useperlio, useshrplib, etc.)

        Reorganize the structure of some of the hints.

        Miscellaneous clarifications.

Index: MANIFEST

        Updated.  5.003_02 introduced some massive patches, mostly
        due to spacing changes.  I didn't bother to sort them all out;
        I just started with 5.003's MANIEFST.

Index: Makefile.SH

        Support the new simplified shared libperl mechanism.

        Use new $make_set_make directive.

        Remove redundant libperl Make variable.

        Remove unnecessary MAB variable.

        Remove dependency of minitest on lib/Config.pm, since it could
        well have been a failure of configpm that inspired testing
        miniperl in the first place!

Index: Porting/Glossary

        New file describing all the config.sh variables.
        Eventually, I hope to fill this directory with other useful
        stuff.

Index: README.os2

        Replace old README.os2 with more up-to-date os2/README.

Index: config_H

        Updated to match current Configure and config_h.SH.
        Some rearrangement of parts has occurred due to new
        dependencies in the metaconfig units.

Index: config_h.SH

        Updated to match current Configure and config_h.SH.
        Some rearrangement of parts has occurred due to new
        dependencies in the metaconfig units.

        Include full descriptions of ARCHLIB, OLDARCHLIB, PRIVLIB,
        SITEARCH, and SITELIB.  Previous versions just included the
        ~-expanded names (with unhelpful descriptions).  No functionality
        is changed, but maybe it's a little better documented now.

Index: doio.c

        Possibly Include <signal.h> and <unistd.h>

Index: doop.c

        No longer prefer bcmp over memcmp when order doesn't matter.

        Support bit operations on strings longer than 15 bytes.

Index: embed.h

        Auto-generated.

Index: embed.pl

        Expand warning at the top.

Index: ext/IO/IO.pm

        Clean up docmentation installation errors.

Index: ext/IO/lib/IO/Seekable.pm

        Clean up docmentation installation errors.

Index: ext/IO/lib/IO/Select.pm

        Clean up docmentation installation errors.

Index: ext/Opcode/Opcode.xs

        Add support for tied filehandles.

Index: ext/SDBM_File/sdbm/sdbm.h

        Change the Mymalloc to match Perl_malloc in perl.h.

Index: ext/util/make_ext

        Typo change.

Index: handy.h

        Change safe*alloc functions to have prototypes that
        match the system's malloc and free types.  That is, use
        Malloc_t instead of char *, and Free_t instead of void.
        This is necessary so . . .

        Safefree cast matches type of free() whether it's perl's
        malloc/free or the system's malloc/free.

Index: hints/next_3.sh

        Build up $mab dynamically.  Since $mab isn't used anywhere
        anymore, this is useless.  However, $mab was never used for
        next_3.sh anyway, so there's been no change in functionality.

Index: hints/next_4.sh

        Get rid of extraneous isnext_4 variable.  Configure and
        Makefile.SH will use $osname and $osvers instead.

        Build up $mab dynamically based on available architectures.

        Absorb $mab into ccflags and ccdlflags.  I hope that will
        cover everything.  (Configure should automatically remove
        the -arch stuff from cppflags.)

        Configure now knows next4 needs to use a shared libperl.5.so.

        Allow users to use -Dprefix.

----------------
Version 5.003_02
----------------
o Visible Changes to Core Functionality
  - Redefining constant subs, or changing sub's prototype now give warnings.
  - Fixes for ++/-- of values close to max/min size of an integer 
  - Warning for un-qualified bareword as handler in $SIG{}. 
  - UNIVERSAL::isa can now be called as static method. 

o Changes in Core Internals
  - PerlIO abstraction added.
    Perl core and standard extensions no longer assume ANSI C's stdio is IO
    mechanism, Default Configure mode is still to use stdio via set of C macros.
    Alternate modes are to use stdio via one perlio.c module, or 
    to use sfio if available.
    
  - Several bug fixs from perl5-porters
      - Make sources non-ANSI C correct again.
      - SUPER in gv.c 
      - Last of shared-hash-key patches
      - eval '(0,1..3)'; # --> SegFault
      - coredumps after simple subsitutes.
      - Correction to UNIVERSAL::VERSION docs.
      - Fixed io_udp test.
      - Fixed another abuse of malloc'ed memory.
  - Enabled DEBUGING_MSTATS whenever perl's malloc() is used.
  - Reverted to default of not hiding perl's malloc (if used). 

o Changes in the Standard Library and Utilities
  - Fixed MakeMaker for static SDBM and builing in a link tree.
  - Upgraded to IO-1.09, and includes latest (still experimental) IO::Select. 
  - Documentation/test tweak to DB_File
  - h2xs upgrade to allow use C::Scan module 

o Changes in OS-specific and Build-time Support
  - Attempted to re-created 5.003_01's NeXT support with metaconfig units.
  - Updated MANIFEST 
  - make minitest now depends on lib/Config.pm, as some of tests require it. 
  - Included latest plan9 sub-directory
  - Applied OS/2 patches.
  - Typo patch for VMS.

----------------
Version 5.003_01
----------------

Version 5.003_01 contains bugfixes and additions accumulated since
version 5.002_01, since the patch to version 5.003 was deliberately
kept simple.  In addition to numerous small bugfixes in the core,
library files, and documentation, this patch contains several
significant revisions, summarized below:

o Visible Changes to Core Functionality

  - A port to Plan9 has been started, and changes are integrated into
    the standard distribution.  As of this release, the Perl core
    and several common extensions are working.

  - A set of basic methods in the UNIVERSAL class have been added to
    the Perl core.  Since UNIVERSAL is an implicit member of every
    class's @ISA, the methods can be called via any object.

  - A mandatory warning has been added for 'declarations' of lexical
    variables using the "my" operator which mask an existing lexical
    variable declared in the same scope, making the previous variable
    inaccessible by its name.

  - The "use" and "require" operators have been extended to allow
    checking of the required module's version.  The "use" operator
    can now be used for an immediate version check of Perl itself.

  - A new "strict" pragma, "strict untie", has been added, which
    produces an error if a tied value is untied when other references
    exist to the internal object implementing the tie.

  - Barewords used as associative array keys (i.e. when specifying
    an associative array element like $foo{__BAR} or on the left
    side of the => operator) may now begin with an underscore as
    well as an alphabetic character.

  - Some of the configuration information previously produced by the
    -v switch has been moved to the -V switch, in order to keep -v
    output concise.

o Changes in Core Internals

  - Symbol table and method lookups have been made faster.

  - Perl subroutines which just return a constant value are now
    optimized at compile time into inline constants.

  - Management of keys for associative arrays has been improved to
    conserve space when the same keys are reused frequently, and
    to pass true Perl values to tie functions, instead of stringified
    representations.

  - Messages normally output to stderr may be directed to another
    stream when Perl is built.  This allows some platforms to
    present diagnostic output in a separate window from normal
    program results.

  - A bug which caused suiperl to fail silently, albeit securely,
    in version 5.003 on some systems has been fixed.

  - Management of Unix-style signal handlers via the %SIG associative
    array has been made safer.

  - Several global C symbols have been renamed to eliminate collisions
    with system C header files or libraries on some platforms.
    Unfortunately, this means that dynamic extensions compiled under
    previous versions of Perl will need to be rebuilt for Perl
    5.003_01.  We're in the process of cleaning up Perl's C
    namespace to make it easier to link Perl with other binaries,
    so this will probably happen again between now and version 5.004.
    After that, we'll do our best to maintain binary compatibility
    between versions.

  - An alternate allocation strategy has been added to Perl's
    optional private memory management routines.  This strategy,
    which may be selected when Perl is built, is designed to
    conserve memory in programs which allocate many small
    chunks of memory with sizes near a power of 2, as is often
    the case in Perl programs.

  - Several memory leaks in the creation and destruction of
    multiple interpreters have been fixed.

o Changes in the Standard Library and Utilities

  - The Opcode extension, which allows you to control a program's
    access to Perl operations, has been added to the standard
    distribution.  This extends the work begun in the original
    Safe extension, and subsumes it.  The Safe interface is still
    available.

  - The IO extension, which provides a set of classes for object-
    oriented handling of common I/O tasks, has been added to the
    standard distribution.  The IO classes will form the basis
    for future development of Perl's I/O interface, and will
    subsume the FileHandle class in the near future.  The default
    class to which all Perl I/O handles belong is now IO::Handle,
    rather than FileHandle.

  - The ExtUtils::Embed library module, which provides a set
    of utility function to help in embedding Perl in other
    applications, has been added to the standard distribution.

  - The Fatal library module, which provides a simple interface
    for creating "do-or-die" equivalents of existing functions,
    has been added to the standard distribution.

  - The FindBin library module, which determines the full path
    to the currently executing program, has been added to the
    standard distribution.

  - The DB_File extension, and the Getopt::Long, Test::Harness,
    Text::Tabs, Text::Wrap, Time::Local and sigtrap library modules
    have been updated to the authors' latest versions.

  - The Carp library module now considers the @ISA chain when
    determining the caller's package for inclusion in error messages.

  - The h2xs, perlbug, and xsubpp utilities have been updated.

  - The standard Perl debugger has been updated, and the information
    provided to the debugger when an XSUB is called has been improved,
    making it possible for alternate debuggers (such as Devel::DProf)
    to do a better job of tracking XSUB calls.

  - The pod documentation formatting tools in the standard distribution
    can now handle characters in the input stream whose high bit is set.

  - The cperl-mode EMACS editing mode has been updated.

o Changes in Documentation

  - Typographic and formatting errors have been corrected in the pod
    documentation for the core and standard library files

  - Explanations of several core operators have been improved

  - The perldebug, perlembed, perlipc, perlsec, and perltrap documents
    extensively revised.

o Changes in OS-specific and Build-time Support

  - Support for the NeXT platform has been extended through
    NeXTSTEP/OPENSTEP 4.0, and now includes the ability to create MABs.

  - Support for OS/2 has been extended as well, and now includes
    options for building a.out binaries.

  - Support for VMS has also been extended, incorporating improved
    processing of file specification strings, optional suppression of
    carriage control interpretation for record-structured files,
    improved support for the -S command line switch, a number of
    VMS-specific bugfixes, and significantly improved performance
    in line-oriented reading of files.

  - Several hints files have been added or updated: aux.sh (updated),
    convexos.sh (updated), irix_4.sh (updated), irix_5.sh (updated),
    irix_6_2.sh (updated), next_3.sh (updated), next_3_2.sh (new),
    next_3_3.sh (new), next_4.sh (new), os2/sh (updated),
    sco.sh (updated), and solaris_2.sh (updated).

  - The test driver for the regression tests now reports when a set
    of tests have been skipped (presumable because the operation
    they're designed to test isn't supported on the current system).
