v101
  - parse svg xml to extract top level desc tag contents to handle svg alt strings
  
v100
  - restrict adding xml:lang attribute to epub3 opf package tags
  - instead of exiting when audio, video, javascript, and mathml are used in the epub
      the accessbility schema metadata is simply not added, but all other functionality is employed

v097
  - fix whitespace indentaion error caused by copy /paste

v096
   - better handle cases when no xmpxml is available

v095
   - add support for auto filling in empty image alt-text attributes based
     on image XMP AltTextAccessibility metadata or exif ImageDescription metadata

v091
   - reverted to allowing duplicate images each with their own alt tag per link
   - Fix bug in Alt Text Editor cancel not actually canceling the image alt text updates

v090 - Beta
  - completely removed the  use of the Tk graphical user interface for image
    alt text editing becasue Tk and Pillow have no support for pure svg images.
    
    To replace it, The Qt for Python graphical user interface as provided by
    PySide6 (for Qt6) and PyQt5 (for Qt5) is used instead.  The resulting Qt
    based Alt Text Editing dialog is much improved and much more stable.

    As a result the new minimum supported version of Sigil is ***Sigil 1.60 or later***

  - if the OPF package tag does not have an xml:lang element to indicate the primary
    language of its metadata tags, one is now added based the primary epub dc:language
