- specfile:
* update copyright year
* removed modname variable
- update to version 1.0.0:
* Faster
+ “python setup.py build” is 18.7 times faster
+ Function-call overhead cut in half—a big speed up for small
input arrays
+ Arbitrary ndim input arrays accelerated; previously only 1d, 2d,
and 3d
+ bn.nanrankdata is twice as fast for float input arrays
+ bn.move_max, bn.move_min are faster for int input arrays
+ No speed penalty for reducing along all axes when input is
Fortran ordered
* Smaller
+ Compiled binaries 14.1 times smaller
+ Source tarball 4.7 times smaller
+ 9.8 times less C code
+ 4.3 times less Cython code
+ 3.7 times less Python code
* Beware
+ Requires numpy 1.9.1
+ Single API, e.g.: bn.nansum instead of bn.nansum and
nansum_2d_float64_axis0
+ On 64-bit systems bn.nansum(int32) returns int32 instead of
int64
+ bn.nansum now returns 0 for all NaN slices (as does numpy 1.9.1)
+ Reducing over all axes returns, e.g., 6.0; previously
np.float64(6.0)
+ bn.ss() now has default axis=None instead of axis=0
+ bn.nn() is no longer in bottleneck
* min_count
+ Previous releases had moving window function pairs: move_sum,
move_nansum
+ This release only has half of the pairs: move_sum
+ Instead a new input parameter, min_count, has been added
+ min_count=None same as old move_sum; min_count=1 same as old
move_nansum
+ If # non-NaN values in window < min_count, then NaN assigned to
the window
+ Exception: move_median does not take min_count as input
* Bug Fixes
+ Can now install bottleneck with pip even if numpy is not already
installed
+ bn.move_max, bn.move_min now return float32 for float32 input

- Update to version 0.8.0
- This version of Bottleneck requires NumPy 1.8
- nanargmin and nanargmax behave like the corresponding functions in NumPy 1.8
- nanargmax/nanargmin wrong for redundant max/min values in 1d int arrays

Tue Oct 22 12:07:46 UTC 2013 - toddrme2178@gmail.com
- Update to version 0.7.0
+ bn.rankdata() is twice as fast (with input a = np.random.rand(1000000))
+ C files now included in github repo; cython not needed to try latest
+ C files are now generated with Cython 0.19.1 instead of 0.16
+ Test bottleneck across multiple python/numpy versions using tox
+ Source tarball size cut in half

- %py_requires is only needed for SLE_11_SP2 (and older), newer Python
package releases generate the RPM requires for the Python ABI automatically
-------------------------------------------------------------------
Fri Jun 22 12:25:12 UTC 2012 - saschpe@suse.de
- Update to version 0.6.0:
+ replace(arr, old, new), e.g, replace(arr, np.nan, 0)
+ nn(arr, arr0, axis) nearest neighbor and its index of 1d arr0 in 2d arr
+ anynan(arr, axis) faster alternative to np.isnan(arr).any(axis)
+ allnan(arr, axis) faster alternative to np.isnan(arr).all(axis)
+ Python 3.2 support (may work on earlier verions of Python 3)
+ C files are now generated with Cython 0.16 instead of 0.14.1
+ Upgrade numpydoc from 0.3.1 to 0.4 to support Sphinx 1.0.1
+ Support for Python 2.5 dropped
+ Default axis for benchmark suite is now axis=1 (was 0)
+ #31 Confusing error message in partsort and argpartsort
+ #32 Update path in MANIFEST.in
+ #35 Wrong output for very large (2**31) input arrays
