1.3.0

For a list of all changes in this release, see the [full changelog](https://github.com/nci/scores/compare/1.2.0...1.3.0). Below are the changes we think users may wish to be aware of.

Introduced Support for Python 3.13 and Dropped Support for Python 3.9

- In line with other scientific Python packages, `scores` has dropped support for Python 3.9 in this release.
`scores` has added support for Python 3.13. See [PR 710](https://github.com/nci/scores/pull/710).

Features

- Added four new metrics:
- Quantile Interval Score: `scores.continuous.quantile_interval_score`. See [PR 704](https://github.com/nci/scores/pull/704), [PR #733](https://github.com/nci/scores/pull/733) and [PR #738](https://github.com/nci/scores/pull/738).
- Interval Score: `scores.continuous.interval_score`. See [PR 704](https://github.com/nci/scores/pull/704), [PR #733](https://github.com/nci/scores/pull/733) and [PR #738](https://github.com/nci/scores/pull/738).
- Kling-Gupta Efficiency (KGE): `scores.continuous.kge`. See [PR 679](https://github.com/nci/scores/pull/679), [PR #700](https://github.com/nci/scores/pull/700) and [PR #734](https://github.com/nci/scores/pull/734).
- Interval threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.interval_tw_crps_for_ensemble`. See [PR 682](https://github.com/nci/scores/pull/682) and [PR #734](https://github.com/nci/scores/pull/734).
- Added an optional `include_components` argument to several continuous ranked probability score (CRPS) functions for ensembles. If supplied, the `include_components` argument will return the underforecast penalty, the overforecast penalty and the forecast spread term, in addition to the overall CRPS value. This applies to the following CRPS functions:
- continuous ranked probability score (CRPS) for ensembles: `scores.probability.crps_for_ensemble`
- threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.tw_crps_for_ensemble`
- tail threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.tail_tw_crps_for_ensemble`
- interval threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.interval_tw_crps_for_ensemble`)
See [PR 708](https://github.com/nci/scores/pull/708) and [PR #734](https://github.com/nci/scores/pull/734).

Documentation

- Added "Kling–Gupta Efficiency (KGE)" tutorial. See [PR 679](https://github.com/nci/scores/pull/679), [PR #700](https://github.com/nci/scores/pull/700) and [PR #734](https://github.com/nci/scores/pull/734).
- Added "Quantile Interval Score and Interval Score" tutorial. See [PR 704](https://github.com/nci/scores/pull/704), [PR #736](https://github.com/nci/scores/pull/736) and [PR #738](https://github.com/nci/scores/pull/738).
- Added "Threshold Weighted Continuous Ranked Probability Score (twCRPS) for ensembles" tutorial. See [PR 706](https://github.com/nci/scores/pull/706) and [PR #722](https://github.com/nci/scores/pull/722).
- Updated the title in the "Binary Categorical Scores and Binary Contingency Tables (Confusion Matrices)" tutorial and the description for the corresponding thumbnail in the tutorial gallery. See [PR 741](https://github.com/nci/scores/pull/741) and [PR #743](https://github.com/nci/scores/pull/743).
- Updated the pull request template. See [PR 719](https://github.com/nci/scores/pull/719).

Internal Changes

- Sped up (improved the computational efficiency of) the continuous ranked probability score (CRPS) for ensembles. This also addresses memory issues when a large number of ensemble members are present. See [PR 694](https://github.com/nci/scores/pull/694).

1.2.0

For a list of all changes in this release, see the [full changelog](https://github.com/nci/scores/compare/1.1.0...1.2.0). Below are the changes we think users may wish to be aware of.

Features

- Added three new metrics:
- Percent bias (PBIAS): `scores.continuous.pbias`. See [PR 639](https://github.com/nci/scores/pull/639) and [PR #655](https://github.com/nci/scores/pull/655).
- Threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.tw_crps_for_ensemble`. See [PR 644](https://github.com/nci/scores/pull/644).
- Tail threshold weighted continuous ranked probability score (twCRPS) for ensembles: `scores.probability.tail_tw_crps_for_ensemble`. See [PR 644](https://github.com/nci/scores/pull/644).
- The FIxed Risk Multicategorical (FIRM) score (`scores.categorical.firm`) can now take a sequence of mulitdimensional arrays (xr.DataArray) of thresholds. This allows the FIRM score to be used with categorical thresholds that vary across the domain. See [PR 661](https://github.com/nci/scores/pull/661).

Documentation

- Added information about percent bias to the "Additive Bias and Multiplicative Bias" tutorial. See [PR 639](https://github.com/nci/scores/pull/639) and [PR #656](https://github.com/nci/scores/pull/656).
- Updated documentation to say there are now over 60 metrics, statistical techniques and data processing tools contained in `scores`. See [PR 659](https://github.com/nci/scores/pull/659).
- In the "Contributing Guide", updated instructions for installing a conda-based virtual environment. See [PR 654](https://github.com/nci/scores/pull/654).

Internal Changes

- Modified automated tests to work with NumPy 2.1. Incorporated a union type of `array` and `generic` in assert statements for Dask operations. See [PR 643](https://github.com/nci/scores/pull/643).

1.0.0

We are happy to have reached the point of releasing “Version 1.0.0” of `scores`. While we look forward to many version increments to come, version 1.0.0 represents a milestone. It signifies a stabilisation of the API, and marks a turning point from the initial construction period. We have also published a [paper](https://doi.org/10.21105/joss.06889) in the Journal of Open Source Software (see citation further below).

From this point forward, `scores` will be following the [Semantic Versioning Specification](https://semver.org/) (SemVer) in its release management.

This is a good moment to acknowledge and thank the contributors that helped us reach this point. They are: Tennessee Leeuwenburg, Nicholas Loveday, Elizabeth E. Ebert, Harrison Cook, Mohammadreza Khanarmuei, Robert J. Taggart, Nikeeth Ramanathan, Maree Carroll, Stephanie Chong, Aidan Griffiths and John Sharples.
