19 Version 0.4.0 14.04.2011
22 * full Python 3 support, also for Cython implementations
23 * removed user defined compare() function - keys have to be comparable!
24 * removed T.has_key(), use 'key in T'
25 * keys(), items(), values() generating 'views'
26 * removed iterkeys(), itervalues(), iteritems() methods
27 * replaced index slicing by key slicing
28 * removed index() and item_at()
29 * repr() produces a correct representation
30 * installs on systems without cython (tested with pypy)
31 * new license: GNU Library or Lesser General Public License (LGPL)
33 Version 0.3.2 09.04.2011
35 * added itemslice(startkey, endkey), keyslice(startkey, endkey),
36 valueslice(startkey, endkey) - slicing by keys
37 * tested with pypy 1.4.1, damn fast
38 * Pure Python trees are working with Python 3
39 * No Cython implementation for Python 3
41 Version 0.3.1 10.09.2010
43 * runs with Python 2.7
45 Version 0.3.0 11.05.2010
47 * low level functions written as c-module only interface to python is a cython
49 * support for the pickle protocol
51 Version 0.2.1 06.05.2010
53 * added delslice del T[0:3] -> remove treenodes 0, 1, 2
54 * added discard -> remove key without KeyError if not found
55 * added heap methods: min, max, nlarges, nsmallest ...
56 * added Set methods -> intersection, differnce, union, ...
57 * added slicing: T[5:10] get items with position (not key!) 5, 6, 7, 8, 9
58 T[5] get item with key! 5
59 * added index: T.index(key) -> get position of item <key>
60 * added item_at: T.item_at(0) -> get item at position (not key!) 0
61 T.item_at(0) O(n)! <==> T.min_item() O(log(n))
63 Version 0.2.0 - 03.05.2010
65 * TreeMixin Class as base for Python-Trees and as Mixin for Cython-Trees
67 Version 0.1.0 - 27.04.2010
