 If you want the latest code, you generally want the directory {component-name}/trunk,

+<b>Important!</b> At the current time, selecting by date in subversion within the
+ASF repository isn't reliable. The reason is that when converting a date to a revision
+number, subversion assumes that revision N has an earlier date than revision N+M, and
+that it can therefore perform a binary search on revision numbers to locate one with
+the required date. However CVS imports of data that retain the original date
+information from CVS break this assumption. And unfortunately because revisions
+are repository-wide information, this affects date-based searches
+even in directories unrelated to the ones that CVS stuff was imported into.
+So while dates are reported correctly in "svn log" output, only revision numbers should
+be used with the -r option. See issue #752 in the subversion issue tracker at tigris.org.
