Update to 1.8.2 * fix crash caused by unsupported types in binary operations, * speedup initializing or extending a bitarray from another with different bit endianness. * add formatting options to ``bitarray.util.pprint()`` * add and improve tests (all 291 tests run in less than half a second on a modern machine) - Update to 1.8.1 * moved implementation of and ``hex2ba()`` and ``ba2hex()`` to C-level * add ``bitarray.util.parity()`` - Update to 1.8.0 * add ``bitarray.util.serialize()`` and ``bitarray.util.deserialize()`` * allow whitespace (ignore space and ``\n\r\t\v``) in input strings; e.g. ``bitarray('01 11')`` or ``a += '10 00'`` * add ``bitarray.util.pprint()`` * When initializing a bitarray from another with different bit endianness, e.g. ``a = bitarray('110', 'little')`` and ``b = bitarray(a, 'big')``, the buffer used to be simply copied, with consequence that ``a == b`` would result in ``False``. This is fixed now, that is ``a == b`` will always evaluate to ``True``. * add test for loading existing pickle file (created using bitarray 1.5.0) - Update to 1.7.1 * Raise TypeError when incorrect index is used during assignment, e.g. ``a[1.5] = 1`` * raise TypeError (not IndexError) when assigning slice to incorrect type, e.g. ``a[1:4] = 1.2`` * improve some docstrings and tests - Update to 1.7.0 * add ``bitarray.util.urandom()`` * raise TypeError when trying to extend bitarrays from bytes on Python 3, ie. ``bitarray(b'011')`` and ``.extend(b'110')``. (Deprecated since 1.4.1) - Update to 1.6.2 * use ``Py_SET_TYPE()`` and ``Py_SET_SIZE()`` for Python 3.10 * add official Python 3.10 support * fix slice assignment to same object, e.g. ``a[2::] = a`` or ``a[::-1] = a``, * add bitarray.h, ------------------------------------------------------------------- Fri Nov 6 10:48:49 UTC 2020 - Martin Hauke <mardnh@gmx.de> - Update to 1.6.1 * use PyType_Ready for all types: bitarray, bitarrayiterator, decodeiterator, decodetree, searchiterator. - Update to 1.6.0 * add `decodetree` object, for speeding up consecutive calls to `.decode()` and `.iterdecode()`, in particular when dealing with large prefix codes. * add optional parameter to `.tolist()` which changes the items in the returned list to integers (0 or 1), as opposed to Booleans. * remove deprecated `bitdiff()`, which has been deprecated since version 1.2.0, use `bitarray.util.count_xor()` instead * drop Python 2.6 support. * update license file. ------------------------------------------------------------------- Wed Sep 30 04:35:36 UTC 2020 - Steve Kowalik <steven.kowalik@suse.com> - Update to 1.5.3: * add optional index parameter to `.index()` to invert single bit * fix `sys.getsizeof(bitarray)` by adding `.__sizeof__()`, see issue #100 ------------------------------------------------------------------- Mon Aug 31 04:58:58 UTC 2020 - Steve Kowalik <steven.kowalik@suse.com> - Update to 1.5.2: * add PyType_Ready usage, issue #66 * speedup search() for bitarrays with length 1 in sparse bitarrays, see issue #67 * add tests * support signed integers in `util.ba2int()` and `util.int2ba()`, see issue #85 * deprecate `.length()` in favor of `len()` * Use `Py_ssize_t` for bitarray index. This means that on 32bit systems, the maximun number of elements in a bitarray is 2 GBits. We used to have a special 64bit index type for all architectures, but this prevented us from using Python's sequence, mapping and number methods, and made those method lookups slow. * speedup slice operations when step size = 1 (if alignment allows copying whole bytes) * Require equal endianness for operations: `&`, `|`, `^`, `&=`, `|=`, `^=`. This should have always been the case but was overlooked in the past. * raise TypeError when tring to create bitarray from boolean * This will be last release to still support Python 2.6 (which was retired in 2013). We do NOT plan to stop support for Python 2.7 anytime soon. ------------------------------------------------------------------- Wed Aug 5 00:59:24 UTC 2020 - Steve Kowalik <steven.kowalik@suse.com> - Update to 1.4.2: * C-level: - simplify pack/unpack code - fix memory leak in `~` operation (bitarray_cpinvert) * add official Python 3.9 support * improve many docstrings * add DeprecationWarning for `bitdiff()` * add DeprecationWarning when trying to extend bitarrays from bytes on Python 3 (`bitarrays(b'011')` and `.extend(b'110')`) * C-level: - rewrote `.fromfile()` and `.tofile()` implementation, such that now the same code is used for Python 2 and 3. The new implementation is more memoery efficient on Python 3. - use memcmp() in richcompare to shortcut EQ/NE, when comparing two very large bitarrays for equality the speedup can easily be 100x - simplify how unpacking is handled * add more tests * add `.clear()` method (Python 3.3 added this method to lists) * avoid overallocation when bitarray objects are initially created * raise BufferError when resizing bitarrays which is exporting buffers * add example to study the resize() function * improve some error messages * raise `NotImplementedError` with (useful message) when trying to call the `.fromstring()` or `.tostring()` methods, which have been removed in the last release ------------------------------------------------------------------- Mon Jul 6 18:40:25 UTC 2020 -

Update to version 1.2.2 * `util.ba2hex` now always return a string object (instead of bytes object for Python 3), see issue #94 * `util.hex2ba` allows a unicode object as input on Python 2 * Determine 64-bitness of interpreter in a cross-platform fashion #91, in order to better support PyPy ------------------------------------------------------------------- Tue Mar 24 18:38:34 UTC 2020 -
