+attr-2.4.40 (?)
+	- In some cases, gcc does not link in functions from libmisc.a
+	  unless libmisc is specifief before the dynamic libraries on
+	  the command line.
+	- Rip out nftw tree walking, it is broken and hopeless to fix.
+	  The replacement walk_tree() function does exactly what we
+	  want, and is much simpler to use.
+	- Add a test case for tree walking.
+	- For some reason, test/attr.test broke.
+
 attr-2.4.39 (11 September 2007)
 	- Fix symlink handling with getfattr, thanks to Utako Usaka.

+When walking a tree, it does not make sense to follow symlinks. We should
+only see f's attributes here -- that's a bug:
+	$ getfattr -Rd .
+	> # file: f
+	> user.test="test"
+	>
+
+This case works as expected:
+	$ getfattr -Rhd .
+	> # file: f
+	> user.test="test"
+	>
+
+In these two cases, getfattr should dereference the symlink passed on the
+command line, but not l. This doesn't work correctly, either; it's the same
+bug:
+	$ ln -s . here
+	$ getfattr -Rd here
+	> # file: here/f
+	> user.test="test"
+	>
+
+	$ getfattr -Rhd here
+	> # file: here/f
+	> user.test="test"
+	>
+
+	$ cd ..
+	$ rm -rf d
