   4 See also NEW_FEATURES for things which probably need adding soon.

   6 1. Show the binlogs completely and match them properly
   7 by looking at the pattern defined in the server. Currently I'm using
   8 hard-coded stuff which matches personal usage.
   9
  10 2. Only tested on MySQL 5.6 and MariaDB 10.0. It should be possible
  11 to make this work on MySQL 5.7 but that has not been tested yet.
  12
  13 3. Latency issues over slow connections. Perhaps should use compressed
  14 connection to speed things up?
  15
  16 4. Sometimes I see this:

  31 with a very long latency. Related to doing backups. Need to check the cause
  32 of the 5124.10h ++ issue. Probably a subtraction problem of some sort.

  34 5. Fix the filename encoding for example in sys:
