 ===============
 
 
+v0.18 (2021/06/06)
+------------------
+
+*  ``\inputpygments`` now checks inputted files for modification, so that
+   typeset code will correctly update when the source is changed (#162).
+
+*  Julia now uses project flag "``--project=@.``" (#157, #158).
+
+*  Fixed bug in processing Pygments options (``pygopt``) when a key is used
+   without a value (#181).
+
+*  Some error handling for Windows was incompatible with other operating
+   systems: replaced checks for ``WindowsError`` with checks for ``OSError``
+   (#177).
+
+*  Rust support is now compatible with document and working directory paths
+   that contain spaces (#167).

+% \begin{itemize}
+% \item \texttt{\string\inputpygments} now checks inputted files for modification, so that typeset code will correctly update when the source is changed (\#162).
+% \item Julia now uses project flag ``\texttt{-{}-project=@.}'' (\#157, \#158).
+% \item Fixed bug in processing Pygments options (\texttt{pygopt}) when a key is used without a value (\#181).
+% \item Some error handling for Windows was incompatible with other operating systems: replaced checks for \texttt{WindowsError} with checks for \texttt{OSError} (\#177).
+% \item Rust support is now compatible with document and working directory paths that contain spaces (\#167).

+% This command is useful for inserting Python-generated content in contexts where the normal |\py| and |\pyc| would not function or would be inconvenient due to the restrictions imposed by \LaTeX.  Since Python processes \meta{code} and performs substitutions \emph{before} the result is passed to \LaTeX, substitution fields may be anywhere, including within parts of \meta{code} that will become \LaTeX\ comments.
 %
 % Literal exclamation points |!| in \meta{code} only need to be escaped when they immediately precede an opening curly brace |{|, or when they precede exclamation points that precede a brace.  Escaping is performed by doubling.  Thus, |!!{| would indicate a literal exclamation point followed by a literal curly brace (|!{|), not the beginning of a substitution field.  And |!!!{| would indicate a literal exclamation point (|!!|) followed by a substitution field (|!{...}|).  Because curly braces |{}| only have the meaning of field delimiters when immediately following a non-escaped exclamation point, curly braces never need to be escaped.
