+Version 5.003
+-------------
+
+ ***> IMPORTANT NOTICE: <***
+The main reason for this release was to fix a security bug affecting
+suidperl on some systems. If you build suidperl on your system, it
+is strongly recommended that you replace any existing copies with
+version 5.003 or later immediately.
+
+The changes in 5.003 have been held to a minimum, in the hope that this
+will simplify installation and testing at sites which may be affected
+by the security hole in suidperl. In brief, 5.003 does the following:
+
+- Plugs security hole in suidperl mechanism on affected systems
+
+- MakeMaker was also updated to version 5.34, and extension Makefile.PLs
+ were modified to match it.
+
+- The following hints files were updated: bsdos.sh, hpux.sh, linux.sh,
+ machten.sh, solaris_2.sh
+
+- A fix was added to installperl to insure that file permissions were
+ set correctly for the installed C header files.
+
+- t/op/stat.t was modified to work around MachTen's belief that /dev/null
+ is a terminal device.
+
+- Incorporation of Perl version information into the VMS' version of
+ config.h was changed to make it compatible with the older VAXC.
+
+- Minor fixes were made to VMS-specific C code, and the routine
+ VMS::Filespec::rmsexpand was added.
+
+----------------
+Version 5.002_01
+----------------
+
+- The EMBED namespace changes are now used by default, in order to better
+ segregate Perl's C global symbols from those belonging to embedding
+ applications or to libraries. This makes it necessary to rebuild dynamic
+ extensions built under previous versions of Perl without the EMBED option.
+ The default use of EMBED can be overridden by placing -DNO_EMBED on the
+ cc command line.
+
+ The EMBED change is the beginning of a general cleanup of C global
+ symbols used by Perl, so binary compatibility with previously
+ compiled dynamic extensions may be broken again in the next few
+ releases.
+
+- Several bugs in the core were fixed, including the following:
+ - made sure FILE * for -e temp file was closed only once
+ - improved form of single-statement macro definitions to keep
+ as many ccs as possible happy
+ - fixed file tests to insure that signed values were used when
+ computing differences between times.
+ - fixed toke.c so implicit loop isn't doubled when perl is
+ invoked with both the -p and -n switches
+
+- The new SUBVERSION number has been included in the default value for
+ architecture-specific library directories, so development and
+ production architecture-dependent libraries can coexist.
+
+- Two new magic variables, $^E and $^O, have been added. $^E contains the
+ OS-specific equivalent of $!. $^O contains the name of the operating
+ system, in order to make it easily available to Perl code whose behavior
+ differs according to its environment. The standard library files have
+ been converted to use $^O in preference to $Config{'osname'}.
+
+- A mechanism was added to allow listing of locally applied patches
+ in the output of perl -v.
+
+- Miscellaneous minor corrections and updates were made to the documentation.
+
+- Extensive updates were made to the OS/2 and VMS ports
+
+- The following hints file were updated: bsdos.sh, dynixptx.sh,
+ irix_6_2.sh, linux.sh, os2.sh
+
+- Several changes were made to standard library files:
+ - reduced use of English.pm and $`, $', and $& in library modules,
+ since these degrade module loading and evaluation of regular expressions,
+ respectively.
+ - File/Basename.pm: Added path separator to dirname('.')
+ - File/Copy.pm: Added support for VMS and OS/2 system-level copy
+ - MakeMaker updated to v5.26
+ - Symbol.pm now accepts old (') and new (::) package delimiters
+ - Sys/Syslog.pm uses Sys::Hostname only when necessary
+ - chat2.pl picks up necessary constants from socket.ph
+ - syslog.pl: Corrected thinko 'Socket' --> 'Syslog'
+ - xsubpp updated to v1.935
+
+
+- The perlbug utility is now more cautious about sending mail, in order
+ to reduce the chance of accidentally send a bug report by giving the
+ wrong response to a prompt.
+
+- The -m switch has been added to perldoc, causing it to display the
+ Perl code in target file as well as any documentation.
