+Regular expression pattern matching of things like C<qr/[^I<a>]/> is
+significantly sped up, where I<a> is any ASCII character. Which classes
+will get this speed up is complicated and depends on the underlying bit
+patterns of those characters, so differs between ASCII and EBCDIC
+platforms, but all case pairs, like C<qr/[Gg]/> are included, as is
+C<[^01]>.

-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
+Perl's build and testing process on Mac OS X for C<-Duseshrplib>
+builds is now compatible with Mac OS X System Integrity Protection
+(SIP).
+
+SIP prevents binaries in F</bin> (and a few other places) being passed
+the C<DYLD_LIBRARY_PATH> environment variable. For our purposes this
+prevents C<DYLD_LIBRARY_PATH> from being passed to the shell, which
+prevents that variable being passed to the testing or build process,
+so running C<perl> couldn't find F<libperl.dylib>.
+
+To workaround that, the initial build of the F<perl> executable
+expects to find F<libperl.dylib> in the build directory, and the
+library path is then adjusted during installation to point to the
+installed library.

-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]
+L<SDBM_File> is now more robust with corrupt database files. The
+improvements do not make SDBM files suitable as an interchange format.
