Note:: Docutils 0.18.x is the last version supporting Python 2.7, 3.5, and 3.6. * nodes.Node.traverse() returns a list again to restore backwards compatibility (fixes bug #431). * Small bugfixes (see HISTORY_). Release 0.18 (2021-10-26) * Output changes: Identifiers: During `identifier normalization`_, leading number and hyphen characters are no longer stripped from a `reference name`_, if the id_prefix_ setting is non-empty. Example: with ``--id-prefix="DU-"``, a section with title "34. May" currently gets the identifier key ``DU-may`` and after the change the identifier key ``DU-34-may``. The default value for the auto_id_prefix_ setting changed to ``%``: "use the tag name as prefix for auto-generated IDs". Set auto_id_prefix_ to ``id`` for unchanged auto-IDs.
