+Subject: [PATCH] avahi-python: Use the agnostic DBM interface
+
+Also fixes configure failing if Python 3 is the build python and GDBM is
+enabled, since Py3 only has anydbm under the name of 'dbm'.
+
+Not enough to make ServiceTypeDatabase.py compatible with Py3, but it's
+a start.

+Subject: [PATCH] avahi-python: Encode unicode strings as UTF-8
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Previously, we would effectively encode anything representable in
+Latin-1 as Latin-1, and crash on anything not representable in Latin-1:
+
+>>> import avahi
+>>> avahi.string_to_byte_array(u'©')
+[dbus.Byte(169)]
+>>> avahi.string_to_byte_array(u'\ufeff')
+Traceback (most recent call last):
+ File "<stdin>", line 1, in <module>
+ File "/usr/lib/python2.7/dist-packages/avahi/__init__.py", line 94, in string_to_byte_array
+ r.append(dbus.Byte(ord(c)))
+ValueError: Integer outside range 0-255
+
+This is particularly important for Python 3, where the str type
+is a Unicode string.
+
+The b'' syntax for bytestrings is supported since at least Python 2.7.
+
+These functions now accept either Unicode strings (Python 2 unicode,
+Python 3 str), which are encoded in UTF-8, or bytestrings
+(Python 2 str, Python 3 bytes) which are taken as-is.

+Subject: [PATCH] Remove empty avahi_discover Python module
+
+The avahi-discover tool no longer has any code outside its main
+executable, so it does not need to install library modules. Its only
+library code was avahi_discover.SimpleGladeApp, which was removed
+in 2009.
