+=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 encoded internally as utf8 without warnings -- not just the ones that
-are legal in Unicode.
-However, unless UTF8 warnings have been
+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
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.

+ 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.

+
+ 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.

+
+ 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.

+ 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

+
+ 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by

+ utf8.c(): Default to allow problematic code points
+
+ Surrogates, non-character code points, and code points that aren't in Unicode
+ are now allowed by default, instead of having to specify a flag to allow them.
+ (Most code did specify those flags anyway.)
+
+ This affects uvuni_to_utf8_flags(), utf8n_to_uvuni() and various routines that
+ are specialized interfaces to them.
+
+ Now there is a new set of flags to disallow those code points. Further, all 66
+ of the non-character code points are known about and handled consistently,
+ instead of just U+FFFF.
+
+ Code that requires these code points to be forbidden will have to change to use
+ the new flags. I have looked at all the (few) instances in CPAN where these
+ routines are used, and the only one I found that appears to have need to do
+ this, Encode, has already been patched to accommodate this change. Of course,
+ I may have overlooked some subtleties.

+
+ This commit adds Module::Metadata 1.000002 as a dual-life module. It
+ gathers package and POD information from Perl module files. It is a

+ module installation toolchain components. Module::Build::ModuleInfo
+ has been deprecated in favor of this module instead.

+
+ Make newline on last record explicit.
+
+ On VMS, the last line written to a file will get a trailing newline
+ willy nilly. This has its advantages insofar as you never get the
+ "no newline at end of file" warnings from various utilities, but
+ reality conflicts with expectations when you explicitly test for
+ the last (or only) line *not* ending with newline, which is what
+ the recent addtion to ref.t (5e3072707906cc4cb8a364c4cf7c487df0300caa)
+ was doing. Adding an explicit newline makes everyone happy.

+ Add Perl::OSType as a dual-life core module
+
+ This commit adds Perl::OSType 1.002 as a dual-life module. It maps Perl
+ operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic
+ types with standardized names (e.g. "Unix" or "Windows"). It has been
+ refactored out of Module::Build and ExtUtils::CBuilder and consolidates
+ such mappings into a single location for easier maintenance.

+ [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.

+ [perl #36347] Object destruction incomplete
+
+ do_clean_objs only looks for objects referenced by RVs, so blessed
+ array references and lexical variables (and probably other SVs, too)
+ are not DESTROYed.
+
+ This commit adds a new visit() call to sv_clean_objs, which curses
+ (DESTROYs and un-blesses, leaving the reference count as it is) any
+ objects that are still left after do_clean_named_io_objs. The new
+ do_curse routine (a pointer to which is passeds to visit()) follows
+ do_clean_named_io_objs’ example and explicitly skips the STDOUT and
+ STDERR handles, in case destructors need to use them.
+
+ The cursing code, which is now called from two places, is moved out of
+ sv_clear and put in its own routine. The check that the reference
+ count is zero does not apply when called from sv_clean_objs, so the
+ new S_curse routine takes a boolean argument that determines whether
+ that check should take place.

+
+ Due to the way that '<> as glob' was parsed differently from

+ This was contrary to the docs for overload, and meant that <> couldn't

+
+ Better handling of magic methods freeing the SV
+
+ This is a fix for RT #81230 (and more). Currently, mg_get() works around
+ the case where the called magic (e.g. FETCH) frees the magic SV. It does
+ this by unconditionally pushing the SV on the tmps stack before invoking
+ the method.
+
+ There are two issues with this. Firstly, it may artificially extend the
+ life of the SV. This was the root of the problem with #81230. There, the
+ DB_File code, under -T, created a tainted tied object. Accessing the
+ object (within FETCH as it happens), caused mg_get() to be invoked on the
+ object (due to the taint magic), and thus extend the life of the object.
+ This then caused c<untie %h if $h{k}> to give the warning
+ untie attempted while 1 inner references still exist.
+ This only became noticeable after efaf36747029c85b4d8825318cb4d485a0bb350e,
+ which stopped wrapping magic method calls in SAVETMPS/FREETMPS.
+
+ The second issue issue that this protection only applies to mg_get();
+ functions like mg_set() can still segfault if the SV is deleted.
+
+ This commit fixes both problems as follows:
+
+ First, the protection mechanism is moved out of mg_get() and into
+ save_magic() / restore_magic(), so that it protects more things.
+ Secondly, the protection is now:
+
+ * in save_magic(), SvREFCNT_inc() the SV, thus protecting it from being
+ freed during FETCH (or whatever)
+
+ * in restore_magic(), SvREFCNT_dec() the SV, undoing the protection
+ without extending the life of the SV, *except* if the refcount is
+ 1 (ie FETCH tried to free it), then push it on the mortals stack
+ to extend it life a bit so our callers wont choke on it.

+ [perl #81016] Document ord("")

+ From the current documentation, it's not documented what it does, and one
