The following changes were made:
<p><ul>
<li> If the user removes a folder from ~/Library/TeXShop and then runs TeXShop, the folder will be
recreated with default contents. Curiously, this did not apply to the folder ~/Library/TeXShop/Engines/Inactive,
but now it does. Before this change, a user could remove ~/Library/TeXShop/Engines and that entire folder would be recreated, including the
Inactive subdirectory, but that technique destroyed any special engines the user might have created.
<p>When new versions of TeXShop are introduced, most folders in ~/Library/TeXShop are not changed
because these folders store files created and edited by the user. But the Inactive folder is updated because users should have the latest versions of
these items. This update adds new files and folders and modifies existing files and folders, but it does not remove
files or folders no longer needed. I'm thinking of changing this behavior so Inactive is completely
"cleaned up", but that is a more drastic step that needs to be carefully considered. In the meantime,
users can accomplish that complete cleanup by removing the Inactive folder and letting TeXShop
recreate it.
<li> The Typst program was recently updated to version 0.9.0, and Jeroen Scheerder updated the
material in ~/Library/TeXShop/Engines/Inactive/Typst for the new version. If you are already using
Typst in TeXShop, go to this location. An early section in the document "AboutTypst.pdf" explains
how to download and install Typst. Follow these instructions to obtain the new version. The last section
of this document explains how to move the contents of the "Advanced" folder into appropriate places.
Scheerder revised the contents of "Advanced", so move the revised folders into the same spots.
<p><li> Version 5.20 added a preference item to activate transparency when calling Ghostscript. That item
adds a flag to Ghostscript calls, but the flag is only relevant on recent versions of Ghostscript. So
TeXShop checked the version of Ghostscript and did not add the flag if the version being used was
not recent enough. This check involved calling a shell script that was incompetently written (by me) and
failed in Sonoma. The script has been rewritten and the bug is fixed on Sonoma.
<p><li> In version 4.61, the bibtex UTI was changed from org.tug.bib to org.tug.tex.bibtex at the request of the BibDesk
team. But not all data structures were changed, breaking the creation of new bibtex files from within TeXShop. This bug was not noticed until now. It is fixed.
<p><li> Version 5.03 of TeXShop included an example program explaining how to create interactive
documents using tex4ht. The source code for such a document is ordinary latex. When typeset by pdflatex,
the result is a static pdf file. But when typeset by tex4ht, the result is a web page with interactive content.
The sample document is in ~/Library/TeXShop/New/Demo.
<p> Since tex4ht can output MathJax calls, the mathematical formulas on the web pages it creates are essentially perfect. But the
illustrations are sometimes distorted. Recently I read a brief note by Michal Hoftich, who maintains
tex4ht, explaining how to fix this problem. So TeXShop 5.22 installs a new folder,
~/Library/TeXShop/New/Demo-Additions-5.22, containing a Read-Me file explaining the very
simple modification to the Demo document which fixes illustrations. These Read-Me changes can
be made in the same manner to other documents typeset by tex4ht.
