+ * Beautify urls used in various places. (smcv)
+ * Export pagetitle, titlepage, linkpage.
+ * htmltidy: Avoid returning undef if tidy fails. Also avoid returning the
+ untidied content if tidy crashes. In either case, it seems best to tidy
+ the content to nothing.
+ * htmltidy: Avoid spewing tidy errors to stderr.
+ * Reorganize index file, add a format version field. Upgrades to the new
+ index format should be transparent.
+ * Add %wikistate, which is like %pagestate except not specific to a given
+ page, and is preserved across rebuilds.
+ * editpage: Be more aggressive (and less buggy) about cleaning up
+ temporary files rendered during page preview.
+ * Add an indexpages option, which causes foo/index.mdwn to be the source
+ for page foo when foo.mdwn doesn't exist. Closes: #474611
