* Remove dead link from plugins/teximg. Closes: #664885
* inline: When the pagenames list includes pages that do not exist, skip
them.
* meta: Export author information in html <meta> tag. Closes: #664779
Thanks, Martin Michlmayr
* notifyemail: New plugin, sends email notifications about new and
changed pages, and allows subscribing to comments.
* Added a "changes" hook. Renamed the "change" hook to "rendered", but
the old hook name is called for now for back-compat.
* meta: Support keywords header. Closes: #664780
Thanks, Martin Michlmayr
* passwordauth: Fix url in password recovery email to be absolute.
* httpauth: When it's the only auth method, avoid a pointless and
confusing signin form, and go right to the httpauthurl.
* rename: Allow rename to be started not from the edit page; return to
the renamed page in this case.
* remove: Support removing of pages in the transient underlay. (smcv)
* inline, trail: The pagenames parameter is now a list of absolute
pagenames, not relative wikilink type names. This is necessary to fix
a bug, and makes pagenames more consistent with the pagespec used
in the pages parameter. (smcv)
* link: Fix renaming wikilinks that contain embedded urls.
* graphviz: Handle self-links.
* trail: Improve CSS, also display trail links at bottom of page,
and a bug fix. (smcv)
