+% \begin{changelog}{v1.3}{2017/07/08}
+% \item Added \texttt{beameroverlays} option, which enables \texttt{beamer} overlays using the \texttt{<} and \texttt{>} characters.
+% \item Added options \texttt{breakindentnchars}, \texttt{breaksymbolsepleftnchars} (alias \texttt{breaksymbolsepnchars}), \texttt{breaksymbolseprightnchars}, \texttt{breaksymbolindentleftnchars} (alias \texttt{breaksymbolindentnchars}), and \texttt{breaksymbolindentrightnchars}. These are identical to the pre-existing options without the \texttt{nchars} suffix, except that they allow indentation to be specified as an integer number of characters rather than as a dimension. As a result of these new options, \texttt{\string\settowidth} is no longer used in the preamble, resolving some font incompatibilities (\#4).
+% \item Clarified in the docs that \texttt{breaksymbolsepright} is a \emph{minimum}, rather than exact, distance.

-% This is the command that activates Pygments features. It must be invoked before \verb|\begin{Verbatim}|, etc., but inside a |\begingroup...\endgroup| so that its effects do not escape into the rest of the document (for example, within the beginning of an environment. It takes two arguments: The Pygments macro that literally appears (|\PYG| for \pkg{minted} and \pkg{pythontex}), and the Pygments macro that should actually be used (|\PYG|\meta{style\_name} for \pkg{minted} and \pkg{pythontex}). The two are distinguished because it can be convenient to highlight everything using the same literal macro name, and then |\let| it to appropriate values to change styles, rather than redoing all highlighting to change styles. It modifies |\FV at PygmentsHook|, which is at the beginning of |\FV at FormattingPrepHook|, to make the actual changes at the appropriate time.
