IMPROVEMENTS:
+ * ``BTreeIndex`` code now is able to prefetch extra pages to help tune
+ the tradeoff between bandwidth and latency. Should be tuned
+ appropriately to not impact commands which need minimal information,
+ but provide a significant boost to ones that need more context. Only
+ has a direct impact on the ``--development2`` format which uses
+ 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)
