0.2.1

One fix, found by using the generator rather than reading it.

write_post_entries wrote a <time> for every entry in a listing, so a page without a date got <time datetime=""></time>. An empty datetime is not a valid date string, and a <time> carrying no date is not a time.

Only the blog is datedsection_pages says so in a comment two procedures below the bug.. The blog was also the only section anyone had put pages in, and a post is required to carry a date, so the broken shape had never been rendered. It appeared the first time a second section got a page.

write_single has guarded this since it was written; this is the same guard in the other place that writes a time. The fixture site gains a notes/ section holding one undated page, because the golden tree only knows the shapes the fixture contains and this was not one of them.
