ANN: pandoc 3.8

[John G Macfarlane]

I'm pleased to announce the release of pandoc 3.8,
available in the usual places:

Binary packages & changelog:
https://github.com/jgm/pandoc/releases/tag/3.8

Source & API documentation:
http://hackage.haskell.org/package/pandoc-3.8

This release comes with many small improvements and a few larger ones.
Among the more visible changes:

+ A new input/output format xml, which exactly represents a pandoc
  AST in a more easily human-readable form than JSON. The format is
  documented in doc/xml.md, and schemas can be found in tools/pandoc-xml.*.

+ A new command line option --syntax-highlighting, which takes the
  values 'none', 'default', 'idiomatic', a style name, or a path to
  a theme file.  --no-highlighting and --highlight-style are deprecated.

+ New extensions smart_quotes and special_strings for org mode.
  These allow pandoc's parsing to more closely reproduce Emacs org-mode's
  behavior.

+ The old compact_definition_lists extension has been removed.

API changes:

+ New modules Text.Pandoc.Readers.XML (exporting readXML) and
  Text.Pandoc.Writers.XML (exporting writeXML).

+ Text.Pandoc.Extensions: added constructors Ext_smart_quotes,
  Ext_special_strings; removed Ext_compact_definition_lists.

+ Text.Pandoc.App now exports versionInfo, a function that takes
  three parameters that can be filled in by pandoc-cli.

+ Text.Pandoc.Parsing: tableWith and tableWith' now return
  a list of lists of Blocks, allowing for multiple header rows.

+ Text.Pandoc.ImageSize: Add Point and Pica as constructors of
  ImageSize.  Add Avif constructor of ImageType.

+ Text.Pandoc.Class: CommonState is now opaque and does not support
  its fields.  To compensate for this, we now export several
  new functions: getRequestHeaders, setRequestHeaders, getSourceURL,
  getTrace.
