Comment (by kevin_tes):

 Replying to [comment:8 jinmei]:
  Firstly I'd like to express my regret for not reply in time,this week I
 am busy with other things.

 > - xfrout.py compares serials as integers, which is not correct.  we
 >   need to use isc.dns.Serial objects.  See xfrin.
 thanks for notice.
 > - before doing that, add a test case that fails due to the integer
 >   comparison (e.g. 0xffffffff "<" 1).  see, again, xfrin.  Then make
 >   the above change, and then confirm it fixes the problem.
 ok, i'll add it.
 > - ixfr-to-axfr test cases shouldn't be removed (we need to change the
 >   test parameters and check the fallback behavior, not just remove it).
 ok,i'll recover it and changed the test parameters.
 > - I believe we need a changelog for it.
 ok, i'll add it.
