Improvements

Maintenance

Documentation

- Add documentation for window convolution.

Miscellaneous

Bug fixes

- Remove assumption of the same pivot value for both dimensions in double
spherical Bessel transform.

- Enforce `scipy.integrate.simpson` keyword-only argument (scipy>=1.12).

Improvements

- Reduce computational redundancy for spherical orders
([gh-68](https://github.com/MikeSWang/Triumvirate/issues/68)).

- Allow non-mandatory parameters to be missing at initialisation.

- Make OpenMP ``simd`` directives compiler-aware.

- Add and update C++ program runtime information.

Maintenance

- Update tests after computational redundancy refactoring and
parameter validation behaviour changes.

- Add `mpi4py` dependency to Conda environment and project configuration files.

- Refactor syntax and formatting and fix typos.

Bug fixes

Fix file format `fmt` keyword processing error when the reader falls
back from ``'nbodykit'`` to ``'astropy'`` in
[``catalogue.py``](src/triumvirate/catalogue.py).

Improvements

Add various tools to project configuration file: `autopep8`, `codespell`,
`docformatter` and `ruff`.

Maintenance

Update syntax and fix typos.

Bug fixes

Fix Conda package dependency overpinning.

Bug fixes

- Fix asymmetric 2-d three-point clustering statistics.

- Fix various legacy issues in the non-public methods related to
Hankel-like transforms.

- Fix FFTW-related memory leaks.

Features

- Add public API for Hankel-like transforms using the FFTLog algorithm
with enhanced extrapolation options.

- Expose installation validation as a public function.

- Add non-public API for window convolution (as part of a future release).

Improvements

- Add support for FFTW planner flags and wisdom.

- Refactor assignment and aliasing compensation.

- Refactor mesh field (re-)initialisation.

- Refactor gamma function computations.

- Refactor array operation checks.

- Refactor FFTW plans.

- Add logs to ``trv::MeshField`` and ``trv::FieldStats`` operations.

- Add tracking of (I)FFTs and 3-d grids.

- Promote `trv::ParameterSet::nmesh` from type `int` to `long long` and
refactor related methods and variables.

Maintenance

- Require C++17 standard.

- Upgrade build against NumPy 2 and require Python 3.10+
([gh-52](https://github.com/MikeSWang/Triumvirate/issues/52)).

- Refactor logger message emission.

- Enhance build recipes.

- Update syntax and fix typos.

Documentation

- Add version context to documentation.

- Add and update details to/in various documentation components.

Miscellaneous

Relicense under/clarify GPL-3.0-or-later in lieu of GPL-3.0 where applicable.

Bug fixes

Fix reused bin statistics when duplicate recording is designed to be avoided
in [``threept.cpp``](src/triumvirate/src/threept.cpp).

Features

- Add the functionality to record binning details for wavevector modes
and separation pairs from a mesh grid with the option to save the results
to a file in C++.

- Add more forms of three-point statistics including the off-diagonal and
full form (the original 'full' form is renamed to 'row')
([gh-22](https://github.com/MikeSWang/Triumvirate/issues/22)).

Improvements

- Implement further parallelisation and refactoring resulting in
significant speed-up.

- Enhance parameter validation consistency.

Maintenance

- Update syntax and fix typos.

- Add and update test data after API changes.

Documentation

- Add and update details to/in various documentation components.

- Update and rerun tutorial notebooks after API changes.
