+"-1" is not a valid version number under the new "lax" criteria used

+Things that may break your code:
+
+C<url()> was fixed to return C<PATH_INFO> when it is explicitly requested
+with either the C<path=E<gt>1> or C<path_info=E<gt>1> flag.
+
+If your code is running under mod_rewrite (or compatible) and you are
+calling C<self_url()> or you are calling C<url()> and passing
+C<path_info=E<gt>1>, these methods will actually be returning
+C<PATH_INFO> now, as you have explicitly requested or C<self_url()>
+has requested on your behalf.
+
+The C<PATH_INFO> has been omitted in such URLs since the issue was
+introduced in the 3.12 release in December, 2005.
+
+This bug is so old your application may have come to depend on it or
+workaround it. Check for application before upgrading to this release.
+
+Examples of affected method calls:
+
+  $q->url(-absolute => 1, -query => 1, -path_info => 1);
+  $q->url(-path=>1);
+  $q->url(-full=>1,-path=>1);
+  $q->url(-rewrite=>1,-path=>1);
+  $q->self_url();
+
+We no longer read from STDIN when the Content-Length is not set,
+preventing requests with no Content-Length from freezing in some cases.
+This is consistent with the CGI RFC 3875, and is also consistent with
+CGI::Simple.  However, the old behavior may have been expected by some
+command-line uses of CGI.pm.
+
+In addition, the DELETE HTTP verb is now supported.

+and now finally uses strictures.
+
+The typemap logic has been moved into a separate module,

+
+It has a new C<:bsd_glob> export tag, intended to replace C<:glob>.  Like
+C<:glob> it overrides C<glob> with a function that does not split the glob
+pattern into words, but, unlike C<:glob>, it iterates properly in scalar
+context, instead of returning the last file.
+
+There are other changes affecting Perl's own C<glob> operator (which uses

+Together, these upgrades fix a problem with IO::Handle's C<getline> and
+C<getlines> methods.  When these methods are called on the special ARGV
+handle, the next file is automatically opened, as happens with the built-in
+C<E<lt>E<gt>> and C<readline> functions.  But, unlike the built-ins, these
+methods were not respecting the caller's use of the L<open> pragma and
+applying the approprate I/O layers to the newly-opened file
+[rt.cpan.org #66474].

+never correct for it to call C<can>, as overloading does not respect
+AUTOLOAD.  So classes that autoload methods and implement C<can> no longer
+have to account for overloading [perl #40333].
+
+A warning is now produced for invalid arguments.  See L</New Diagnostics>.
+
+=item *
+
+L<PerlIO::scalar> has been upgraded from version 0.11 to 0.14.
+
+(This is the module that implements C<< open $fh, '>', \$scalar >>.)
+
+It fixes a problem with C<< open my $fh, ">", \$scalar >> not working if
+C<$scalar> is a copy-on-write scalar. (5.14.2)
+
+It also fixes a hang that occurs with C<readline> or C<< <$fh> >> if a
+typeglob has been assigned to $scalar [perl #92258].
+
+It no longer assumes during C<seek> that $scalar is a string internally.
+If it didn't crash, it was close to doing so [perl #92706].  Also, the
+internal print routine no longer assumes that the position set by C<seek>
+is valid, but extends the string to that position, filling the intervening
+bytes (between the old length and the seek position) with nulls
+[perl #78980].
+
+Printing to an in-memory handle now works if the $scalar holds a reference,
+stringifying the reference before modifying it.  References used to be
+treated as empty strings.
+
+Printing to an in-memory handle no longer crashes if the $scalar happens to
+hold a number internally, but no string buffer.
+
+Printing to an in-memory handle no longer creates scalars that confuse
+the regular expression engine [perl #108398].
+
+=item *
+
+L<Pod::Functions> has been upgraded from version 1.04 to 1.05.
+
+F<Functions.pm> is now generated at perl build time from annotations in
+F<perlfunc.pod>.  This will ensure that L<Pod::Functions> and L<perlfunc>
+remain in synchronisation.
+
+=item *
+
+L<Pod::Html> has been upgraded from version 1.11 to 1.1502.
+
+This is an extensive rewrite of Pod::Html to use L<Pod::Simple> under
+the hood.  The output has changed significantly.
+
+=item *
+
+L<Pod::Perldoc> has been upgraded from version 3.15_03 to 3.17.
+
+It corrects the search paths on VMS [perl #90640]. (5.14.1)
+
+The B<-v> option now fetches the right section for C<$0>.
+
+This upgrade has numerous significant fixes.  Consult its changelog on
+the CPAN for more information.
+
+=item *
+
+L<POSIX> has been upgraded from version 1.24 to 1.30.
+
+L<POSIX> no longer uses L<AutoLoader>.  Any code which was relying on this
+implementation detail was buggy, and may fail as a result of this change.
+The module's Perl code has been considerably simplified, roughly halving
+the number of lines, with no change in functionality.  The XS code has
+been refactored to reduce the size of the shared object by about 12%,
+with no change in functionality.  More POSIX functions now have tests.
+
+C<sigsuspend> and C<pause> now run signal handlers before returning, as the
+whole point of these two functions is to wait until a signal has
+arrived, and then return I<after> it has been triggered.  Delayed, or
+"safe", signals were preventing that from happening, possibly resulting in
+race conditions [perl #107216].
+
+C<POSIX::sleep> is now a direct call into the underlying OS C<sleep>
+function, instead of being a Perl wrapper on C<CORE::sleep>.
+C<POSIX::dup2> now returns the correct value on Win32 (I<i.e.>, the file
+descriptor).  C<POSIX::SigSet> C<sigsuspend> and C<sigpending> and
+C<POSIX::pause> now dispatch safe signals immediately before returning to
+their caller.
+
+C<POSIX::Termios::setattr> now defaults the third argument to C<TCSANOW>,
+instead of 0. On most platforms C<TCSANOW> is defined as 0, but on some
+0 is not a valid parameter, which caused a call with defaults to fail.
+
+=item *
+
+L<Socket> has been upgraded from version 1.94 to 2.000.
+
+It has new functions and constants for handling IPv6 sockets:
+
+    pack_ipv6_mreq
+    unpack_ipv6_mreq
+    IPV6_ADD_MEMBERSHIP
+    IPV6_DROP_MEMBERSHIP
+    IPV6_MTU
+    IPV6_MTU_DISCOVER
+    IPV6_MULTICAST_HOPS
+    IPV6_MULTICAST_IF
+    IPV6_MULTICAST_LOOP
+    IPV6_UNICAST_HOPS
+    IPV6_V6ONLY
+
+=item *
+
+L<Storable> has been upgraded from version 2.27 to 2.34.
+
+It no longer turns copy-on-write scalars into read-only scalars when
+freezing and thawing.
+
+=item *
+
+L<Sys::Syslog> has been upgraded from version 0.27 to 0.29.
+
+This upgrade closes many outstanding bugs.
+
+=item *
+
+L<Term::ANSIColor> has been upgraded from version 3.00 to 3.01.
+
+Only interpret an initial array reference as a list of colors, not any initial
+reference, allowing the colored function to work properly on objects with
+stringification defined.
+
+=item *
+
+L<Term::ReadLine> has been upgraded from version 1.07 to 1.09.
+
+Term::ReadLine now supports any event loop, including unpublished ones and
+simple L<IO::Select>, loops without the need to rewrite existing code for
+any particular framework [perl #108470].
+
+=item *
+
+L<threads::shared> has been upgraded from version 1.37 to 1.40.
+
+Destructors on shared objects used to be ignored sometimes if the objects
+were referenced only by shared data structures.  This has been mostly
+fixed, but destructors may still be ignored if the objects still exist at
+global destruction time [perl #98204].
+
+=item *
+
+L<Unicode::Collate> has been upgraded from version 0.73 to 0.89.
+
+Updated to CLDR 1.9.1
+
+Locales updated to CLDR 2.0: mk, mt, nb, nn, ro, ru, sk, sr, sv, uk,
+zh__pinyin, zh__stroke
+
+Newly supported locales: bn, fa, ml, mr, or, pa, sa, si, si__dictionary,
+sr_Latn, sv__reformed, ta, te, th, ur, wae.
+
+Tailored compatibility ideographs as well as unified ideographs for the
+locales: ja, ko, zh__big5han, zh__gb2312han, zh__pinyin, zh__stroke.
+
+Locale/*.pl files are now searched for in @INC.
+
+=item *
+
+L<Unicode::Normalize> has been upgraded from version 1.10 to 1.14.
+
+Fixes for the removal of F<unicore/CompositionExclusions.txt> from core.
+
+=item *
+
+L<Unicode::UCD> has been upgraded from version 0.32 to 0.43.
+
+This adds four new functions:  C<prop_aliases()> and
+C<prop_value_aliases()>, which are used to find all the Unicode-approved
+synonyms for property names, or to convert from one name to another;
+C<prop_invlist> which returns all the code points matching a given
+Unicode binary property; and C<prop_invmap> which returns the complete
+specification of a given Unicode property.
+
+=item *
+
+L<Win32API::File> has been upgraded from version 0.1101 to 0.1200.
+
+Added SetStdHandle and GetStdHandle functions
