+\section{Changes introduced in 2021-06-01 patch~1}
+
+A further refinement to the handling of ``raw'' option lists added
+in the last release, see \ghissue{508}.
+
+Fixes an issue with rollback when \pkg{latexrelease} is loaded by some
+other package (as done for \texttt{platex} (\ghissue{577}).
+
+First aid for \pkg{ulem} and \pkg{varwidth} got added to help them
+along until they get corrected. \pkg{ulem} has a problem with the
+improved definition of \cs{hspace} and \pkg{varwidth} chokes on a
+newly introduced glue item in vertical lists, which is needed for
+paragraph hook handling (\ghissue{583}).
+
+
+\section{Changes introduced in 2021-06-01}
+The focus of this release is to provide further important building
+blocks for the future production of reliable tagged PDF output. Many
+other improvements have been made. Please see \ltnewsissue{33} for an
+overview of the new features and the change log in
