Quoting from John MacFarlane’s announcement mail:
I’m pleased to announce the release of pandoc 2.8,
available in the usual places:
A full list of changes (including some API changes) can be found at
Improvements to the template language, adding ‘elseif’,
‘it’, partials, filters, and syntax to control nesting
and reflowing of text. These changes make pandoc more
suitable for generating plain text documents (even
tables and enumerated lists) from data in YAML metadata.
For an example, see #37 in https://pandoc.org/demos.html.
Template syntax is now described fully in the manual.
A new --defaults flag allows you to specify a collection of
default option values in a YAML file.
–list-extensions=FORMAT now lists only extensions affecting FORMAT,
and the use of an unsupported extension raises an error.
New option --shift-heading-level, replacing --base-heading-level.
This supports converting documents that use an initial level-1
heading for the document title.
–metadata-file can now be used with multiple metadata files.
Text is used instead of String throughout the API.
The ‘unlisted’ class may now be used to prevent an unnumbered
heading from appearing in the table of contents.
Multiple YAML metadata blocks are now merged differently:
when the same field is given values by two different blocks,
the conflict is resolved in favor of the second (and similarly
Note that lua filters that use ‘hierarchicalize’ will need to
be changed to use ‘make_sections’ instead, and Haskell filters
and programs using ‘hierarchicalize’ will need to be rewritten
to use ‘makeSections’.
Many bugs have been fixed, and many small improvements
have been made. We recommend that all users upgrade.
