  BUG FIXES: 
 
11
 
 
12
    * ``GraphIndex`` objects will internally read an entire index if more
 
13
      than 1/20th of their keyspace is requested in a single operation.
 
14
      This largely mitigates a performance regression in ``bzr log FILE``
 
15
      and completely corrects the performance regression in ``bzr log``.
 
16
      The regression was caused by removing an accomodation which had been
 
17
      supporting the index format in use. A newer index format is in
 
18
      development which is substantially faster. (Robert Collins)
