+libregexp-grammars-perl (1.029-1) UNRELEASED; urgency=low
+
+  Warning: Regexp::Grammars is unsupported under Perl 5.18.
+
+  Perl 5.18 changed how 'qr' constant overloadings are parsed
+  and the scope in which they are subsequently compiled. This
+  change appears to make it impossible to reliably create 'qr'
+  overloadings that inject code blocks into a regex, as it
+  prevents the overloaded regexes from compiling properly in
+  many cases, even with an explicit 'use re "eval"' in scope.
+  In a few cases, the use of a 'qr' overloading causes Perl
+  5.18 to segfault.
+
+  Because Regexp::Grammars relies on 'qr' overloads to inject
+  code blocks into regexes, the module is not compatible with
+  Perl 5.18. It may continue to work in some limited cases,
+  but is no longer reliable.
+
+  So far we have been unable to find a workaround for this
+  fundamental incompatibility, and there seems little prospect
+  of a fix unless the behaviour of regex parsing/compilation
+  is changed again in some future release of Perl. At present,
+  if you rely on Regexp::Grammars for your parsing needs, your
+  alternatives are either not to upgrade to Perl 5.18, or else
+  to consider switching to another parsing system, such as Marpa.
+
+  We deeply regret that Regexp::Grammars can no longer be
+  maintained due to these backwards-incompatible changes in
+  Perl 5.18.
