========================
Breadcrumbs now start with the main Nextstrain doc home page and don't include
current page title, along with a couple other small changes for clarity.
The logo now links to https://docs.nextstrain.org by default instead of
https://nextstrain.org, which feels more "right" to several members of the
team. A new option, ``logo_link``, allows control of the URL used for the
logo's link if necessary (though this is unexpected for Nextstrain docs).
The "Click here to return …" message is gone from subproject sidebars in favor
of the improved breadcrumbs at the top of the page and the change to the logo'
link.
The clarity and precision of the currently displayed project version is
improved. "Stable" now shows the precise version (when available) and "latest"
is described as the "development" version with the precise commit shown.
The documentation versions panel added by Read the Docs now stays docked to the
bottom of the sidebar when expanded instead of becoming unmoored and floating
over the bottom right corner of the page.
