=head1 Notice
[ List each enhancement as a =head2 entry ]
-=head2 New regular expression modifier C</a>
-
-The C</a> regular expression modifier restricts C<\s> to match precisely
-the five characters C<[ \f\n\r\t]>, C<\d> to match precisely the 10
-characters C<[0-9]>, C<\w> to match precisely the 63 characters
-C<[A-Za-z0-9_]>, and the Posix (C<[[:posix:]]>) character classes to
-match only the appropriate ASCII characters. The complements, of
-course, match everything but; and C<\b> and C<\B> are correspondingly
-affected. Otherwise, C</a> behaves like the C</u> modifier, in that
-case-insensitive matching uses Unicode semantics; for example, "k" will
-match the Unicode C<\N{KELVIN SIGN}> under C</i> matching, and code
-points in the Latin1 range, above ASCII will have Unicode semantics when
-it comes to case-insensitive matching. Like its cousins (C</u>, C</l>,
-and C</d>), and in spite of the terminology, C</a> in 5.14 will not
-actually be able to be used as a suffix at the end of a regular
-expression (this restriction is planned to be lifted in 5.16). It must
-occur either as an infix modifier, such as C<(?a:...)> or (C<(?a)...>,
-or it can be turned on within the lexical scope of C<use re '/a'>.
-Turning on C</a> turns off the other "character set" modifiers.
-
-=head2 Any unsigned value can be encoded as a character
-
-With this release, Perl is adopting a model that any unsigned value can
-be treated as a code point and encoded internally (as utf8) without
-warnings -- not just the code points that are legal in Unicode.
-However, unless utf8 warnings have been
-explicitly lexically turned off, outputting or performing a
-Unicode-defined operation (such as upper-casing) on such a code point
-will generate a warning. Attempting to input these using strict rules
-(such as with the C<:encoding('UTF-8')> layer) will continue to fail.
-Prior to this release the handling was very inconsistent, and incorrect
-in places. Also, the Unicode non-characters, some of which previously were
-erroneously considered illegal in places by Perl, contrary to the Unicode
-standard, are now always legal internally. But inputting or outputting
-them will work the same as for the non-legal Unicode code points, as the
-Unicode standard says they are illegal for "open interchange".
-
-=head2 Regular expression debugging output improvement
-
-Regular expression debugging output (turned on by C<use re 'debug';>) now
-uses hexadecimal when escaping non-ASCII characters, instead of octal.
-
=head1 Security
XXX Any security-related notices go here. In particular, any security
[ List each security issue as a =head2 entry ]
+=head2 User-defined regular expression properties
+
+Perl no longer allows a tainted regular expression to invoke a user-defined
+property via C<\p{...}> syntax. It simply dies instead [perl #82616].
+
=head1 Incompatible Changes
XXX For a release on a stable branch, this section aspires to be:
[ List each incompatible change as a =head2 entry ]
-=head2 All objects are destroyed
+=head2 Passing references to warn()
-It used to be possible to prevent a destructor from being called during
-global destruction by artificially increasing the reference count of an
-object.
+An earlier Perl 5.13.x release changed C<warn($ref)> to leave the reference
+unchanged, allowing C<$SIG{__WARN__}> handlers to access the original
+reference. But this stopped warnings that were references from having the
+file and line number appended even when there was no C<$SIG{__WARN__}>
+handler in place.
-Now such objects I<will> will be destroyed, as a result of a bug fix
-L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>.
-
-This has the potential to break some XS modules. (In fact, it break some.
-See L</Known Problems>, below.)
+Now C<warn> checks for the presence of such a handler and, if there is
+none, proceeds to stringify the reference and append the file and line
+number. This allows simple uses of C<warn> for debugging to continue to
+work as they did before.
=head1 Deprecations

-L<CPAN::Meta::YAML> 0.003 has been added as a dual-life module. It supports a

- regcomp: Disallow multi-char folds in lookbehind
-
- The addition of the ANYOFV regnode to treat multi-char folds in a bracketed
- character class has exposed a bug, in which those classes have long been able
- to be varying length (due to the multi-char fold), but the compiler wasn't
- aware of it. Now it is, and hence won't allow those which have multi-char
- folds to be part of a lookbehind pattern, which requires a constant length.
-
- This patch disallows multi-char folds in a lookbehind bracketed character
- class.

- regex: Separate nodes for Unicode semantics \s \w
-
- This patch converts the \s, \w and complements Unicode semantics to
- instead of using the flags field of their nodes to instead use separate
- nodes. This gains some efficiency, especially useful in tight loops and
- backtracking of regexec.c, and prepares the way for easily adding other
- semantic variations, such as /a.
-
- It refactors the CCC_TRY... macros. I tried to break this piece up into
- smaller chunks, but found it much easier to get to this in one step.
- Further patches will do some more refactoring of these.
-
- As part of the CCC_TRY macro refactoring, the lines that include the
- test if (! nextchr) are changed to just look for the end-of-string by
- position instead of it being NUL. In locales, it could be (however
- unlikely), that NUL is a real alphabetic, digit, or space character.

-
- This patch changes the core functions to use the common names for the
- fields that are shared between op.c and regcomp.c, just for consistency
- of using one name throughout the core for the same thing.
-
- A grep of cpan shows that both names are used in various modules; so

- Use multi-bit field for regex character set
-
- The /d, /l, and /u regex modifiers are mutually exclusive. This patch
- changes the field that stores the character set to use more than one bit
- with an enum determining which one. This data structure more
- closely follows the semantics of their being mutually exclusive, and
- conserves bits as well, and is better expandable.
-
- A small API is added to set and query the bit field.

-
- Fix \xa0 matching both [\s] [\S], et.al.
-
- This bug stemmed from Latin1 characters not matching any (non-complemented)
- character class in /d semantics when the target string is no utf8; but having
- unicode semantics when it isn't. The solution here is to add a special flag.
-
- There were several tests that relied on the broken behavior, specifically they
- tested that \xff isn't a printable word character even in utf8. I changed the
- deparse test to instead use a non-printable code point, and I changed the ones
- in re_tests to be TODOs, and will change them back using /a when that is
- shortly added.
-
-
-SECURITY
-
- restrict \p{IsUserDefined} to In\w+ and In\w+
-
- In L<perlunicode/"User-Defined Character Properties">, it says you can
- create custom properties by defining subroutines whose names begin with
- "In" or "Is". However, perl doesn't actually enforce that naming
- restriction, so \p{foo::bar} will call foo::Bar() if it exists.
-
- This commit finally enforces this convention. Note that this broke a
- number of existing tests for properties, since they didn't always use an
- Is/In prefix.
-
-TESTING
-
- test that perl.pod, pod.lst, MANIFEST and the file system are consistent

- regex: Use ANYOFV
-
- This patch restructures the regex ANYOF code to generate ANYOFV nodes instead
- when there is a possibility that it could match more than one character. Note
- that this doesn't affect the optimizer, as it essentially ignores things that
- fit into this category. (But it means that the optimizer will no longer reject
- these when it shouldn't have.)
-
- The handling of the LATIN SHARP s is modified to correspond with this new node
- type.
-
- The initial handling of ANYOFV is placed in regexec.c. More analysis will come
- on that. But there was significant change to the part that handles matching
- multi-char strings. This has long been buggy, with it previously comparing a
- folded-version on one side with a non-folded version on the other.
-
- This patch fixes about 60% of the problems that my undelivered test suite gives
- for multi-char folds. But there are still 17K test failures left, so I'm still
- not delivering that. The TODOs that this fixes will be cleaned up in a later commit

- ithread_create() was relying on the stack not moving. Fix this.
-
- 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
- passing the thread creation arguments as pointers to a block of memory
- holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
- because the block of memory is on the Perl stack, which can move as a side
- effect of being reallocated to extend it. Hence pass in the offset on the
- stack instead, read the current value of the relevant interpreter's stack
- at the point of access, and copy all the SVs away before making any further
- calls which might cause reallocation.

- Generate "Unsupported socket function" stubs using PL_ppaddr.
-
- Instead of having each socket op conditionally compile as either the
- implementation or a DIE() depending on #HAS_SOCKET
-
- 1: remove the conditional code from the ops themselves
- 2: only compile the ops if HAS_SOCKET is defined
- 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
- either the ops, or Perl_unimplemented_op
- 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
- ops (ie not the "panic"... message)
-
- Whilst this complicates the support code in regen/opcode.pl, it's already a
- net saving of 5 lines in the C code.

- [perl #81032] Overhaul Porting/epigraphs.pod
-
- This patch makes multiple changes to Porting/epigraphs.pod and
- pod/perlhist.pod.
-
- For those that don't know, Porting/epigraphs.pod is a new document that
- collects the quotes (chosen by Pumpkins) in perl release announcements.
-
- The changes are the following.
-
- 1. Add a link pointing to each release announcement in the mailing
- list archives. These are from ysth's list, the source from which
- Porting/epigraphs.pod was originally compiled, but they weren't in
- Porting/epigraphs.pod so far.
- 2. Reorder Porting/epigraphs.pod chronologically, because I believe
- that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
- 3. Incidentally, some missing releases are added to pod/perlhist.pod too.
- 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
- 5. Add some epigraphs that appear in ysth's list but not in
- Porting/epigraphs.pod.
- 6. I did some research in perl history before the part that ysth's list
- covers, and added older perl announcements I found. This work is not
- complete: I stopped somewhere in 2000.
