+perldelta - what is new for perl v5.31.4
=head1 DESCRIPTION
-This document describes differences between the 5.31.1 release and the 5.31.2
+This document describes differences between the 5.31.3 release and the 5.31.4
release.
-If you are upgrading from an earlier release such as 5.31.0, first read
-L<perl5311delta>, which describes differences between 5.31.0 and 5.31.1.
+If you are upgrading from an earlier release such as 5.31.2, first read
+L<perl5313delta>, which describes differences between 5.31.2 and 5.31.3.
=head1 Notice
[ List each enhancement as a =head2 entry ]
+=head2 Now can dump compiled patterns before optimization
+
+This is primarily useful for tracking down bugs in the regular
+expression compiler. This dump happens on C<-DDEBUGGING> perls, if you
+specify C<-Drv> on the command line; or on any perl if the pattern is
+compiled within the scope of S<C<use re qw(Debug DUMP_PRE_OPTIMIZE)>> or
+S<C<use re qw(Debug COMPILE EXTRA)>>. (All but the 2nd case display
+other information as well.)

-C<\N{} here is restricted to one character> is now emitted in the same
-circumstances where previously C<\N{} in inverted character class or as
-a range end-point is restricted to one character> was.
-
-This is due to new circumstances having been added in perl v5.30 that
-weren't covered by the earlier wording.

-The C<ECHO> macro is now defined. This is used in a C<dtrace> rule
-that was originally changed for FreeBSD, and the FreeBSD make
-apparently predefines it. The Solaris make does not predefine C<ECHO>
-which broke this rule on Solaris. [perl #134218]

=item *
-The PERL_DESTRUCT_LEVEL environment variable was formerly only honored on
-perl binaries built with DEBUGGING support. It is now checked on all perl
-builds. Its normal use is to force perl to individually free every block
-of memory which it has allocated before exiting, which is useful when
-using automated leak detection tools such as valgrind.
-
-=item *
-
-The API eval_sv() now accepts a C<G_RETHROW> flag. If this flag is
-set and an exception is thrown while compiling or executing the
-supplied code, it will be rethrown, and eval_sv() will not return.

-As part of the fix for [perl #2754] perl_parse() now returns non-zero
-if exit(0) is called in a C<BEGIN>, C<UNITCHECK> or C<CHECK> block.

=item *
-Parsing incomplete hex or binary literals was changed in 5.31.1 to
-treat such a literal as just the 0, leaving the following C<x> or C<b>
-to be parsed as part of the next token. This could lead to some
-silent changes in behaviour, so now incomplete hex or binary literals
-produce a fatal error. [perl #134125]

-
-eval_pv()'s I<croak_on_error> flag will now throw even if the
-exception is a false overloaded value. [perl #134177]

-
-C<INIT> blocks and the program itself are no longer run if exit(0) is
-called within a C<BEGIN>, C<UNITCHECK> or C<CHECK> block. [perl
-#2754]
+Perl no longer treats strings starting with "0x" or "0b" as hex or
+binary numbers respectively when converting a string to a number.
+This reverts a change in behaviour inadvertently introduced in perl
+5.30.0 intended to improve precision when converting a string to a
+floating point number. [perl #134230]
