0.5.0
Every page on this site sat under a breadcrumb that said blog. The section is
called Release Notes. It has been called Release Notes since it existed, in the
title of its _index.md, which is what the section heading has always shown.
The trail printed p.section, which is the directory name. That is a URL
segment. It is only the section’s name when the two happen to be the same word,
and the coincidence held for long enough to look deliberate: every directory
anyone had made was already lowercase, so the trail looked like a considered
lowercase style rather than a path being printed where a name belonged.
The crumb is the section’s title now, lowercased the way a crumb at the content
root already lowercased its page title. The link is unchanged: the href is
still the directory, because that is what a URL is made of.
<a href="/blog/">release notes</a>
Upgrading
A site whose section directories match their titles sees no change. A site
where they differ sees the title, which is the point. If a section should be
called what its directory is called, that is the title in its _index.md.
