				First, add warnings with <b>-v</b>.
				This reports MultiMarkdown and CommonMark violations.
				Second, add the <b>-e</b> and <b>-d</b> flags to enable and disable, respectively, Markdown features.
				For a list of Markdown features, see <a href="lowdown.1.html">lowdown(1)</a>.
				Third, implement MultiMarkdown meta-data with the <i>metadata</i> feature, enabled by default.
				Lastly, deprecate the title argument, <b>-t</b>, in favour of the metadata.
				The <a href="lowdown.3.html">lowdown(3)</a> interface has changed to accommodate for the new metadata features.
				Add a <b>-E</b> flag to extract metadata directly, too.
			</p>
			<p>
				<strong>Note</strong>: metadata values are still not used within the document.
				So you can't <q>fill in</q> metadata keys within the text.
				The metadata tags, for now, are informational except in that they provide a title.
				This will be expanded upon in later versions.
			</p>
			<p>
				Lastly, remove the behaviour of printing the first HTML paragraph within an <code>&lt;aside&gt;</code>.
				This is now deprecated by metadata parsing.

				Significantly update the parser to pass newline status to the front-ends, allowing (finally) for formatted links
				for the <b>-Tms</b> and <b>-Tman</b> outputs when in GNU extension mode.
				In the former case, this uses <code>.pfdhref</code>.
				In the latter cases, <code>.UL</code>.
				Doing this involved touching basically the entire backend.
				It was not pretty.
				I've described the problems in the <q>Hacking</q> section of the web site.
			</p>
			<p>
				Disable the <q>semantic quotes</q> (where in HTML mode quotes would be rendered as
				<code>&lt;q&gt;</code>) and <q>underline as emphasis</q>, which rendered emphasis as an underline.
				The underlines aren't easy in <b>-Tms</b> and <b>-Tman</b> and presentationally confusing (is it a link?) in
				<b>-Thtml</b>.

				Significant internal re-write, moving from <q>in-line</q> production of output to production of a parse tree,
				which in turn is used to create output.
				This removed a tremendous amount of cruft from <i>document.c</i>, including several structural elements such as pools and stacks.
				The only notable difference is that PDF output with hyperlinks looks better.
				(HTML output should look the same.)
			</p>
			<p>
				Add <code>html-head-ids</code> as a tunable output option for HTML.

			<p>
				Add the <code>CSS</code> metadata key recognised in the HTML standalone output.
				Also, document the accepted metadata keys better in the manpage.
			</p>
			<p>
				The library functions have been simplified, with the standalone functions being removed in favour of output options.
				The next releases will include more library functions currently undocumented in the header file.

				With smart typography no longer a per-formatter case, overhaul the
				library interface for extracting metadata.
				This was not possible before because the smart typography applied to
				formatted output; thus, metadata needed to be rendered and then
				converted (and escaped, too).
				Metadata is now extracted during rendering so that a caller
				requesting (e.g.) HTML metadata is passed the correct, formatted
				sequence.
			</p>
			<p>
				Eliminate verbose <q>warning</q> output, as it was only used in a
				handful of cases and required enough infrastructure to avoid it.
			</p>
			<p>
				Re-write options to use <q>longopts</q> notation.
				So instead of applying <b>-Dnroff-groff</b> or whatnot, use long
				options such as <b>--nroff-groff</b>.
				This is much easier to document and expands to allowing option values.
				The existing method is no longer documented, but still works.
				This is documented in <a href="lowdown.1.html">lowdown(1)</a>.
			</p>
			<p>
				Add many options for <b>-Tterm</b> output: margins, widths, URL
				shortening, etc.
				Have paragraph content be indented and also consistently indent
				other block levels to line them up.
			</p>
			<p>
				Lastly, add a <b>-Tnull</b> output for fuzzing.
				This makes for a tighter coverage map to focus on parsing and smart
				typography.

				Add class and identifier extended attributes to headers.  These are
				stipulated in PHP Markdown Extra.  Documentation in
				<a href="lowdown.5.html">lowdown(5)</a>.
			</p>
			<p>
				When using header identifiers (the default) and the names collide,
                                use pandoc's method of creating unique header names. Also handle
                                the case of markup in headers and the identifier created from those
				to also be like pandoc.  This isn't a fix, but rather make output
				consistent with other tools.
			</p>
			<p>
				Fix output of how links are handled in <b>-Tms</b> when part of
				headers.  The same applies to other block-level macros with link
				children such as in definition lists.  This also cleans up how
				headers are shown in the PDF TOC.  While here, make header identifiers
				the same as in <b>-Thtml</b> so that intra-document links are 
				consistent, and enable linking within a document using the PDF
				markers.
			</p>
			<p>
				Fix footnotes to be actual footnotes in <b>-Tlatex</b> and
				<b>-Tms</b> instead of endnotes.  The other formats (<b>-Tman</b>,
				etc.) all continue to use endnotes.  The note system has internally
				been cleaned up and now allows for more flexible note placement,
				e.g., side-notes.
			</p>
			<p>
				Allow footnotes to properly exist in <b>-Tlatex</b> tables.  Also
				allow for table alignment.
			</p>
			<p>
                                Bump the minor number as the ABI has been tidied up with respect to
				footnotes: they're now all in their <code>LOWDOWN_FOOTNOTE</code>
				blocks instead of split into definitions and references.
				The <code>LOWDOWN_DOC_FOOTER</code> element, which was not used, has
                                also been removed.
			</p>
			<p>
				The system in general has spent many, many computer-hours being
				fuzzed with <a href="https://lcamtuf.coredump.cx/afl/">AFL</a>
				thanks to hardware donated by Michael Dexter. Thank you!
			</p>
			<p>
				Finally, make <b>-T</b> be a synonym for the new <b>-t</b>, which is
				used by pandoc.

				Add support for
				<a href="https://pandoc.org/MANUAL.html#extension-pandoc_title_block">
					pandoc title blocks
				</a>
				as a metadata block syntax choice.
				Pandoc and MMD syntaxes are mutually exclusive, so only one may be

				Add the <b>--html-titleblock</b> option.

			</p>
			<p>
				Pandoc has a poorly-executed feature where <b>-stman</b> outputs
				have the title metadata line additionally parsed into a manpage
				title, section, and optional source and volume.  This allows titles
				like <code>TITLE(1) Source | Volume</code> to be split into their
				respective manpage parts&#8212;but only when in <b>-stman</b> mode,
				so an HTML document generated from the same page will not inherit
				the additional parsing.
				In <a href="lowdown.5.html">lowdown(5)</a>, introduce this parsing
				for <i>all</i> outputs if <b>--parse-mantitle</b> is specified,
				which is now the default.
			</p>
			<p>
				<b>Behaviour change</b>: do not use <q>Untitled article</q> as the
				default title for media supporting (or requiring) titles when in
				standalone <b>-s</b> mode.  Instead, just the empty string if a
				title is required.  This is a more logical choice: not only is
				<q>Untitled article</q> language-specific, it also assumes the
				output is an article.  For the previous behaviour,
				<b>-mtitle="Untitled article"</b> may always be used.
			</p>
			<p>
				Fix support for
				<a href="https://github.github.com/gfm/#table">GFM tables</a>.
