• Added explicit GNU cp, as the --update flag is useful for only copying files when needed.

• Added use of lockfile to ensure that there aren’t multiple copies of sitecopy trying to write to the site state file at once. I’m not convinced that this is actually necessary as there should only ever be one instance running at a time, but corruption of the site state file seems to be more common than it should be. We can always remove it again if it doesn’t help.

• Moved output file specification section to end so that it can use environment variables in the path. (This is also the recommended location for this anyway.)

• Added a PDF to PDF (rename) rule. (Surprised we never had one before now!)

• Added conditionals to enable building of PDF from LaTeX using XeLaTeX.

• Fixed default font size for lectures (should be 11pt, not 12pt).

• Removed course outline as a target, as it’s no longer part of the handbook.

• Fixed bug with whitespace in LATEX_OPTS variable that caused LaTeX to ignore the options entirely.

• Switched to using \def instead of \newcommand for pre-\begin{document} definitions, as it seems safer.

• Fixed stupid bug that caused custom LaTeX options to be ignored.

• Changed the way that LaTeX document class options are handled.

• Corrected comment on LATEX_OPTS variable.

• Added PAPER_YEAR and PAPER_PERIOD to key variables.

• Added formal Unicode support to lecture rules, and to lecture and miscellaneous templates.

• Removed redundant global hyperref options (moved into hypersetup in lecturecommon.sty or individual class files where it’s safer). ...

• Restructured the ifdefs so as to construct a valid options list.

• Restored --export-text-to-path to Inkscape options for PDF output to eliminate aliasing.

• Added a documentation comment to the top of the output to identify relevant information like the year, paper and teaching period.

• Split calendar script configuration out into a separate (untracked) script. ...

• Changed includes to requires.
