+ * `phases.registernew` now takes a set of revisions instead of a list
+ of nodes. `phases.advanceboundary` takes an optional set of revisions
+ in addition to the list of nodes. The corresponeding members of the
+ `phasecache` class follow this change.

+ * The `addgroup` member of `revlog` classes no longer keeps a list of
+ all found nodes. It now returns True iff a node was found in the group.
+ An optional callback for duplicated nodes can be used by callers to keep
+ track of all nodes themselve.

+ to a LRU cache.
