				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 qoutes 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>
			<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.
