    * ``BTreeIndex`` code now is able to prefetch extra pages to help tune
 
20
      the tradeoff between bandwidth and latency. Should be tuned
 
21
      appropriately to not impact commands which need minimal information,
 
22
      but provide a significant boost to ones that need more context. Only
 
23
      has a direct impact on the ``--development2`` format which uses
 
24
      btree's for the indexes. (John Arbash Meinel)

    * ``bzr dump-btree`` is a hidden command introduced to allow dumping

      the contents of a compressed btree file.  (John Arbash Meinel)
