+The BUILD_STATIC and ALL_STATIC makefile options for linking some or (nearly)
+all extensions statically (into perl519.dll, and into a separate
+perl-static.exe too) were broken for MinGW builds. This has now been fixed.
+
+The ALL_STATIC option has also been improved to include the Win32 extension,
+and also the Encode extension for VC++ builds. (However, Encode and
+Compress/Raw/Bzip2 are currently still excluded from MinGW builds. This will
+hopefully be rectified soon.)

+C<@_> is now correctly visible in the debugger, fixing a regression
+introduced in v5.18.0's debugger. [RT #118169]

Evaluating large hashes in scalar context is now much faster, as the number
of used chains in the hash is now cached for larger hashes. Smaller hashes
continue not to store it and calculate it when needed, as this saves one IV.
the same name had countermanded C<use subs>, causing subsequent mentions of
the constant to use the built-in keyword instead. This has been fixed.
+=item *
+
+Lexical constants (C<my sub a() { 42 }>) no longer crash when inlined.
+
+=item *
+
+Parameter prototypes attached to lexical subroutines are now respected when
+compiling sub calls without parentheses. Previously, the prototypes were
+honoured only for calls I<with> parentheses. [RT #116735]
+
+=item *
+
+Syntax errors in lexical subroutines in combination with calls to the same
+subroutines no longer cause crashes at compile time.
+
+=item *
+
+The warning produced by C<-l $handle> now applies to IO refs and globs, not
+just to glob refs. That warning is also now UTF8-clean. [RT #117595]
+
+=item *
+
+Various memory leaks involving the parsing of the C<(?[...])> regular
+expression construct have been fixed.
+
+=item *
+
+C<(?[...])> now allows interpolation of precompiled patterns consisting of
+C<(?[...])> with bracketed character classes inside (C<$pat =
+S<qr/(?[ [a] ])/;> S</(?[ $pat ])/>>). Formerly, the brackets would
+confuse the regular expression parser.
+
+=item *
+
+The "Quantifier unexpected on zero-length expression" warning message could
+appear twice starting in Perl v5.10 for a regular expression also
+containing alternations (e.g., "a|b") triggering the trie optimisation.
+
+=item *
+
+C<delete local $ENV{nonexistent_env_var}> no longer leaks memory.
+
+=item *
+
+C<sort> and C<require> followed by a keyword prefixed with C<CORE::> now
+treat it as a keyword, and not as a subroutine or module name. [RT #24482]
+
+=item *
+
+Through certain conundrums, it is possible to cause the current package to
+be freed. Certain operators (C<bless>, C<reset>, C<open>, C<eval>) could
+not cope and would crash. They have been made more resilient. [RT #117941]
+
+=item *
+
+Aliasing filehandles through glob-to-glob assignment would not update
+internal method caches properly if a package of the same name as the
+filehandle existed, resulting in filehandle method calls going to the
+package instead. This has been fixed.
