Corrfunc-2.5.3

2.5.3 (06/08/2024)

This is a minor release to add support for numpy2. This is also the last Corrfunc release to support python2 and (likely) the last Corrfunc v2.x release. We have dropped testing for python2 on the CI. Minimum required versions of dependencies are:

- python2 >= 2.7
- python3 >= 3.9
- numpy >= 1.20

Note you do not need python to use Corrfunc from the command line.

Corrfunc-2.5.0

2.5.0 (2022-12-23)

This release lets users specify independent periodic lengths along each of the 3 axes. Calculations with periodic boundary conditions can now be done with max. separations up to half of the boxsize (or up to half of the smallest periodic length in case of non-cubic configurations).

Enhancements

• Allow user to specify periodicity and box size per dimension [#276]
• Allow larger Rmax (up to half the boxsize) [#277]

Changes

• Add Corrfunc/tests.py to CI testing [#260]
• Migrate doctests to Python 3.8 [#261]
• Migrate Python tests to pytest [#265]

Fixes

• Add additional check to tell if it's safe to redirect stdout/err [#270]
• Check and fix z vs cz in DDrppi_mocks and DDsmu_mocks only if comoving distance flag is not set [#275]
• Update GNU assembler bug detection [#278]
• Fix installation instructions and update README.rst [#285]

Corrfunc-2.4.0

2.4.0 (2021-09-30)

This release adds the boxsize parameter to the command line interfaces and
requires the user to specify the box size in the Python interfaces to the periodic
theory functions. It also contains a number of performance, code-quality, and
user-experience improvements.

Breaking Changes

• Require user to specify boxsize rather than automatically detect particle
  extent in periodic theory boxes. Applies to Python, command line, and C API.
  The order of some Python keyword args has also changed. [#199]

Enhancements

• In the theoretical VPF calculation (theory.vpf), the total volume of the random spheres can now exceed the volume of the sample [#238]
• Gridlink (the binning of particles into cells) now uses a parallel algorithm for the theory module [#239]
• Add detection of known-bad Cray hugepages library at NERSC [#246]
• Replace np.float with np.float64 to fix numpy 1.20 deprecation [#250]
• Test Numpy versions as old as 1.14 and recent as 1.20 [#251]
• Add lscpu and preprocessor defs to CI output [#259]

Bug fixes

• Fix Python reference leak to results struct [#229]
• Fix parsing error when periodic=False and boxsize not given in the theory module [#257]

Corrfunc-2.3.4

2.3.4 (2020-07-21)
