+0.091		2025-10-06	T. R. Wyant
+    Code review on use of 'PPI::Document'. I concluded it was not needed
+    in PPIx::Regexp::Token::Interpolation and
+    PPIx::Regexp::Token::Literal, but that it needed to be added to
+    PPIx::Regexp::Tokenizer. The purpose of this release is to submit
+    the changes to the tender mercies of the CPAN testers.

+0.090_01	2025-09-27	T. R. Wyant
+    Avoid "Possible attempt to escape whitespace" warning, which is
+    emitted in perl-5.43.2 and forward. Thanks to James E. Keenan for
+    the pull request.
