  ####Change log####
+ 
+ v1.06 (29 August 2023):
+ - Extensive revision of class file, with most code converted to expl3.  Significant streamlining of remaining LaTeX2e code. Minor changes to user interface. No changes to format or design of thesis.
+ - Add user macros for \CopyrightAuthor, \DegreeMonth, \DegreeYear, and \Institution{..}
+ - Drop user macros \CCurl, \PDFRightsText, and \MIT{..}
+ - Reduce volume of pdf metadata required to be added by user
+ - Accommodate author names that end with a period or include a comma (e.g., Martin Luther King, Jr.)
+ - Reduce font size in fira-newtxsf fontset
+ - Update documentation
+ 
  v1.05 (21 July 2023): 
  - Fix bug in toc page number affecting some lists of figures or tables (note: for backward compatibility, remove code in .tex file around \tableofcontents, \listoffigures, and \listoftables so that your code will match the present version)
  - Include thesis submission date in abstract, remove previous degrees from abstract page, and allow May for degree month, per MIT Libraries

 The sample template uses the option \texttt{[twosided]}, which starts major sections (abstract, table of contents, chapters, etc.) on odd-numbered pages.  This arrangement is suitable for two-sided printing, but can lead to empty even-numbered pages. If you do not wish to have this behavior, omit that option.

 PDF/A-2b compliance will be automatic if the \verb|\DocumentMetadata{..}| command is issued before the \verb|\documentclass{..}| command and \textit{provided that your graphics are also compliant}. This command was added to \LaTeX\ in June 2022. For older versions of \LaTeX, the \texttt{mitthesis} class will fall back to loading \texttt{hyperxmp} to support pdf metadata, but PDF/A compliance will require post-processing (for example, by using the PreFlight function of Adobe Acrobat). An up-to-date \LaTeX\ installation is preferred.
 
 Current \LaTeX\ development (ca.~2023) is working toward fully accessible PDF/A out of the box (e.g., PDF/A-2a). Unicode compliance (e.g., PDF/A-2u) depends greatly on your fonts and figures.
