- Update to 0.21.2:
* General:
+ Drop support for Python 3.7 and 3.8.
+ Provide rst2* "console_scripts" entry points (without the .py
extension) instead of installing the rst2*.py front end tools in the
binary PATH.
+ Use docutils --reader=pep --writer=pep_html for a PEP preview.
+ Use python -m docutils.writers.odf_odt.prepstyles to strip the page
size from an ODT writer stylesheet.
+ Use the same CSV format for the :header: option and the main data of
the "csv-table" directive.
+ New option "loading" for the "image" directive. Sets the new attribute
loading of the doctree element.
* Configuration changes:
+ New configuration setting root_prefix. Configurable root directory
for included files.
+ New configuration setting sources for the "buildhtml.py" application.
+ Simpler and more secure input encoding default behaviour:
# Do not use the locale encoding as fallback if Python is started in
UTF-8 mode. Stop using "latin1" as second fallback.
# Remove BOM (U+FEFF ZWNBSP at start of data) only if the
input_encoding configuration setting is None, '', 'utf-8-sig',
'utf-16', or 'utf-32'. Do not remove other ZWNBSPs.
