	\item[Version 1.1, 2026/02/11:] Added icons for control, solids processing, and utilities. Added anchor border code to support polar coordinates for alignment operations. Added pin option for stream descriptions.
	\begin{itemize}
		\item \textbf{(new)} Added 13 new flowsheet icons: 
			\begin{itemize}
				\item COOLING TOWER: utility heat exchanger (induced, forced, natural)
				\item PRV: pressure relief valve
				\item NRV: no return valve
				\item CTRL: controller with options for type, sense, alarm, field display type
				\item PRESS FILTER: press filter (solids separator)
				\item CENTRIFUGE: centrifuge (solids separator)
				\item BELT DRYER: belt dryer (solids separator)
				\item ROTARY DRYER: rotary dryer (solids separator)
				\item CYCLONE: cyclone (solids separator)
				\item BALL MILL: ball mill (solids size reduction)
				\item ROLL CRUSHER: roll crusher (solids size reduction)
				\item GRANULATOR: granulator, aka agglomorator (solids production)
				\item CRYSTALLIZER: crystallizer with integrated heat exchanger loop (solids production)
			\end{itemize}
		\item \textbf{(new)} Added \texttt{pfdpin}, a modified TikZ pin, to provide up to three stream descriptors 
		\item \textbf{(new)} Added \texttt{anchorborder} code for most shapes to support polar alignment notation (\textit{e.g.}, \texttt{shape.45}). 
		\item Changed default \texttt{unit int} key value to be \texttt{none} (instead of \texttt{empty}) to be more consistent with other TikZ and PFDIcons defaults.
		\item Forced text color of numbered columns to always be black (supports column fill colors).
	\end{itemize}	
		
	\item[Version 1.0a, 2021/07/26:] Documentation updated
	\begin{itemize}
		\item Fixed a few typos in the stream crossing example of the Quick Reference.
		\item Changed the revision date to be fixed (not using \texttt{\today}).
		\item License normalized to LPPL 1.3c in both \texttt{pfdicons.sty} and \texttt{README.md}.
		\item Forced a page break at Fluid transport to stop a runoff on pg. 10.
		\item Incorporated the \texttt{accsupp} package to enable copy/paste without line numbers, and enabled \texttt{columns=fullflexible} to help minimize the number of erroneous whitespaces.
		\item Fixed a few miscellaneous code alignment mistakes (remnants from an accidental ``hard line break'' in TeXstudio).
	\end{itemize}
		
	\item[Version 1.0, 2021/07/23:] Initial release
		
	\begin{itemize}
		\item Package file: pfdicons.sty
		\item Primary files: README.md, pfdicons-doc.tex, pfdicons-changelog.tex
		\item Derived files: pfdicons-doc.pdf, pfdicons-changelog.pdf.
