+%Version 1.2 (updates): boldfaced (`thickened') the truth-functional connectives, existential quantifier, set and relation symbols; added numerous commands for typesetting brackets and substitutions into theorems. 2021/02/23

 In \textit{Principia Mathematica} some symbols occur with an argument and sometimes that same symbol occurs without an argument. For example, `$\pmsome{x}$' occurs in some formulas, but sometimes `$\pmSome$' occurs in the text when they talk about the symbol itself. \texttt{principia} is designed to accommodate these different occurrences of symbols. When a symbol is to occur without an argument, capitalize the first letter following the `\texttt{$\backslash$pm}' part of the command. E.g. \verb|\pmsome{x}| produces $\pmsome{x}$ and \verb|\pmSome| produces `$\pmSome$'. Note the former command requires an argument and the latter command does not. Not all commands in the \texttt{principia} package admit of such dual use because some symbols in \textit{Principia Mathematica} never occur without an argument or do not take an argument in the usual sense. For example, the propositional connectives do not take an `argument' in the way singular or plural descriptions do.
 
-Version 1.1 of \texttt{principia}, like Version 1.0, is adequate to typeset all notations throughout Volume I of \textit{Principia} and includes some fixes to spacing, etc. See the package documentation for details. Updates to include all notations throughout Volumes II and III are planned.
+Version 1.2 (and 1.0-1.1) of \texttt{principia} is adequate to typeset all notations throughout Volume I of \textit{Principia} and includes some fixes to spacing, etc. See the package documentation for details. Updates to include all notations throughout Volumes II and III are planned.
 
 \texttt{principia}'s dependencies are \texttt{amsmath}, \texttt{amssymb}, \texttt{pifont}, \texttt{marvosym}, and \texttt{graphicx}. Make sure to load these package by typing \texttt{$\backslash$usepackage\{graphicx\}}, etc., into the document preamble.
