Sat Apr 10 07:45:02 UTC 2021 - Martin Hauke <mardnh@gmx.de>

- Update to 1.9.2
  * update pythoncapi_compat: Fix support with PyPy 3.7
- Update to 1.9.0
  * add shift operations (``<<``, ``>>``, ``<<=``, ``>>=``)
  * add ``bitarray.util.ba2base()`` and ``bitarray.util.base2ba()``,
- 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

  * drop Python 3.3 and 3.4 support
- Update to version 1.2.2

    bytes object for Python 3), see issue #94

  * Determine 64-bitness of interpreter in a cross-platform
    fashion #91, in order to better support PyPy
