This is a bugfix release. The following have been resolved:
#475: "Loose" lists will now contain paragraphs in all items, not just some.
#433: Links will no longer be double nested
#525: The info-string when beginning a code block may now contain non-word characters (e.g. c++)
#561: The mbstring extension (which we already depend on) has been added explicitly to composer.json
#563: The Parsedown::version constant now matches the release version
#560: Builds will now fail if we forget to update the version constant again 😉
Thanks to @PhrozenByte, @harikt, @erusev, @luizbills, and @aidantwoods for their contributions to this release.
