-=head2 New read-only predefined variable C<${^SAFE_LOCALES}>
-
-This variable is 1 if the Perl interpreter is operating in an
-environment where it is safe to use and change locales (see
-L<perllocale>.) This variable is true when the perl is
-unthreaded, or compiled in a platform that supports thread-safe locale
-operation (see next item).
-
-=head2 Locales are now thread-safe on systems that support them
-
-These systems include Windows starting with Visual Studio 2005, and in
-POSIX 2008 systems.
-
-The implication is that you are now free to use locales and changes them
-in a threaded environment. Your changes affect only your thread.
-See L<perllocale/Multi-threaded operation>

-
-CRTL features can now be set by embedders before invoking Perl by using the
-C<decc$feature_set> and C<decc$feature_set_value> functions. Previously any attempt

-XXX
+The Windows Server 2003 SP1 Platform SDK build, with its early x64 compiler and
+tools, was accidentally broken in Perl 5.27.9. This has now been fixed.
=back
=item *
-A new compiler C<#define>, C<dTHX_DEBUGGING>. has been added. This is
-useful for XS or C code that only need the thread context because their
-debugging statements that get compiled only under C<-DDEBUGGING> need
-one.
-
-=item *
-
-A new API function L<perlapi/Perl_setlocale> has been added.
-
-=item *
-
-L<perlapi/sync_locale> has been revised to return a boolean as to
-whether the system was using the global locale or not.
-
-=item *
-
-A new kind of magic scalar, called a "nonelem" scalar, has been introduced.
-It is stored in an array to denote a nonexistent element, whenever such an
-element is accessed in a potential lvalue context. It replaces the
-existing "defelem" (deferred element) magic wherever this is possible,
-being significantly more efficient. This means that
-C<some_sub($sparse_array[$nonelem])> no longer has to create a new magic
-defelem scalar each time, as long as the element is within the array.
-
-It partially fixes the rare bug of deferred elements getting out of synch
-with their arrays when the array is shifted or unshifted. [perl #132729]

=item *
-Failures while compiling code within other constructs, such as with
-string interpolation and the right part of C<s///e> now cause
-compilation to abort earlier.
-
-Previously compilation could continue in order to report other errors,
-but the failed sub-parse could leave partly parsed constructs on the
-parser shift-reduce stack, confusing the parser, leading to perl
-crashes. [perl #125351]
-
-=item *
-
-On threaded perls where the decimal point (radix) character is not a
-dot, it has been possible for a race to occur between threads when one
-needs to use the real radix character. This has now been fixed by use
-of a mutex on systems without thread-safe locales, and the problem just
-doesn't come up on those with thread-safe locales.
