[0.12.3] 2026-05-14

Added

  • New experimental light_curve.embed module with ONNX-backed light-curve embedding models (#692):
    • Astromer1 and Astromer2 — transformer encoders pretrained on MACHO light curves (Donoso-Oliva et al. 2023/2026). Load directly from HuggingFace with Astromer1.from_hf() / Astromer2.from_hf().
    • ATCAT — multiband transformer pretrained on LSST-like light curves (Tung 2025, arXiv:2511.00614). Load with ATCAT.from_hf().
    • NonOverlappingWindows, Beginning, End, RandomSubsample, MultipleReductions — strategies for mapping variable-length light curves to fixed-length model inputs.
    • InputTensors / AstromerInputs / ATCATInputs — typed dataclass containers for preprocessed tensors.

[0.12.2] 2026-05-09

Changed

  • Development and test dependencies are moved from project extras to dependency-groups in pyproject.toml, so only user-facing optional dependencies are exposed as extras.

Fixed

  • Fixed segmentation fault when using pyarrow 24 on macOS (#694)

[0.12.1] 2026-04-09

Changed

  • Windows PyPI wheels now include Ceres and GSL support, enabled via vcpkg https://github.com/light-curve/light-curve-python/pull/661

[0.12.0] 2026-03-24

Added

  • BazinFit, LinexpFit, and VillarFit gained nuts, nuts-ceres, and nuts-lmsder algorithms using NUTS (No-U-Turn Sampler) for gradient-based Hamiltonian Monte Carlo optimization. New nuts_ntune and nuts_niter parameters control the number of tuning and drawing iterations respectively https://github.com/light-curve/light-curve-python/pull/635

Changed

  • API breaking: .many() now requires arrow_fields argument when called with an Arrow array. Pass a list of 2 or 3 field names (str) or indices (int) to select t, m, and optionally sigma from the struct https://github.com/light-curve/light-curve-python/pull/632
  • Bump light-curve-feature to 0.13.0, rand to 0.10, rand_xoshiro to 0.8 https://github.com/light-curve/light-curve-python/pull/648
  • Build breaking: Minimum supported Rust version (MSRV) bumped from 1.85 to 1.88 https://github.com/light-curve/light-curve-python/pull/648

Deprecated

Removed

--

Fixed

  • .many(arrow_array) now checks for nulls, and raises an error if any nulls presented. Previously we used all the values, even masked, which may cause unexpected results https://github.com/light-curve/light-curve-python/pull/629

Security

--

[0.11.1] 2026-02-16

Added

  • Arrow input support for .many(): pass a List<Struct<t, m[, sigma]>> Arrow array (or chunked array) instead of a list of tuples. Works with any library implementing the Arrow C Data Interface, including pyarrow, polars, nanoarrow, and arro3. Two struct fields means (t, m) without sigma, three fields means (t, m, sigma). Field names are ignored; all fields must share the same float dtype (float32 or float64). https://github.com/light-curve/light-curve-python/pull/621

[0.11.0] 2026-02-12

Added

  • Periodogram now accepts a normalization parameter ('psd', 'standard', 'model', 'log') affecting power() and freq_power() outputs. Default is 'psd' (unchanged behavior). The 'standard', 'model', and 'log' normalizations are consistent with astropy's LombScargle.

Changed

  • PyPI wheels changes:
    • Minimum supported Python version bumped from 3.9 to 3.10 https://github.com/light-curve/light-curve-python/pull/614
    • Linux x86_64 wheels continue to ship with Intel MKL, for its FFT implementation, which is used by Periodogram(fast=True). All other platforms (macOS, Windows, Linux aarch64) now use RustFFT instead of FFTW for FFT. https://github.com/light-curve/light-curve-python/pull/612
  • Breaking Build: Default ABI3 Cargo feature flag now enables Python 3.10 instead of Python 3.9 https://github.com/light-curve/light-curve-python/pull/614
  • Breaking Build: fftw-source (default), fftw-system, and fftw-mkl Cargo features are replaced with a single optional mkl feature. The default FFT backend for the fast periodogram is now RustFFT (pure Rust, no C dependencies). Enable the mkl feature to use FFTW with Intel MKL instead, recommended for Intel CPUs. https://github.com/light-curve/light-curve-python/pull/612
  • Bump light-curve-feature to 0.12.0 https://github.com/light-curve/light-curve-python/pull/611 https://github.com/light-curve/light-curve-python/pull/613
  • Bump light-curve-dmdt to 0.9.0 https://github.com/light-curve/light-curve-python/pull/611
  • Bump pyO3 and rust-numpy from 0.28.0 https://github.com/light-curve/light-curve-python/pull/611

Removed

Changed

  • Breaking RainbowFit is significantly refactored to make it more flexible for usage of different bolometric and temperature functions. It deletes RainbowRisingFit and RainbowSymmetricFit in favor of a single RainbowFit feature. https://github.com/light-curve/light-curve-python/pull/324
  • Breaking: stop supporting Python 3.7 https://github.com/light-curve/light-curve-python/pull/282

[0.8.2] 2024-02-27

Added

  • New flavour of RainbowFit: RainbowSymmetricFit which will replace both RainbowFit and RainbowRisingFit in the future. https://github.com/light-curve/light-curve-python/pull/314 Thanks @karpov-sv for their first contribution
  • New cargo build-time feature, mimalloc, it is default feature now. When activated, it gives up to 2.9x of performance boost for some "fast" features. https://github.com/light-curve/light-curve-python/pull/302

Changed

  • Refactoring of rainbow features, it reduces code duplication and makes it easier to add new variants like RainbowFit and RainbowRisingFit in the future https://github.com/light-curve/light-curve-python/pull/293
  • Another change for Rainbow features is changing minuit optimization parameters https://github.com/light-curve/light-curve-python/pull/314
  • Build breaking: bump light-curve-feature to v0.7.0, which requires ceres-solver v2.2 for ceres-system Cargo feature.

Fixed

  • RainbowFit and RainbowRisingFit initial guesses for baseline fluxes are now consistent with limits. We also use band information to make initial guesses and limits more accurate. Note, that this change leads to different results comparing to previous versions. https://github.com/light-curve/light-curve-python/pull/293

[0.8.1] 2023-11-30

Added

  • RainbowRisingFit experimental feature, https://github.com/light-curve/light-curve-python/pull/278 by @erusseil

[0.8.0] 2023-09-20

Added

  • Breaking change in experimental features: Multiband support is introduced for features implemented in Python. It changes class inheritance interface in a backward-incompatible way
  • light-curve[full] extras which installs all optional Python dependencies required by experimental features
  • New LinexpFit feature for parametric model fit comes with light-curve-feature v0.6.0
  • Experimental RainbowFit feature for fitting multiband light curves with a single model, Russeil+23 in prep. It requires Python 3.8 or later because of iminuit dependency
  • Optional iminuit>=2,<3 Python dependency (included into [full]) for RainbowFit feature
  • Add once_cell v1 dependency

Changed

  • Breaking change in experimental features scipy dependency is now optional for experimental features implemented in Python
  • Breaking change in experimental features: All experimental features implemented in Python require keyword-only arguments in their constructors. Also, all names of the arguments are changed to be the same as for Rust features
  • Build breaking: "abi3-py310" Cargo feature is replaced with "abi3-py311". "abi3" feature is now linked to " abi3-py311" feature. This is because our aim with ABI is to support future versions of Python
  • Build breaking: minimum supported Rust version (MSRV) is changed from 1.62 to 1.67 (released 2023-01-26)
  • Update *Fit fatures doc-strings to list names of the features they output
  • Bump light-curve-feature 0.5.5 -> 0.6.0

[0.7.3] 2023-07-06

Added

  • All Rust features got .to_json() method to serialize their state to JSON string. https://github.com/light-curve/light-curve-python/pull/226
  • New special Rust feature JSONDeserializedFeature and a helper function feature_from_json() to deserialize features from JSON string. https://github.com/light-curve/light-curve-python/pull/226
  • Build: "abi3" and "abi3-py310" Cargo features (the least one is enabled by the first one) to build a wheel for CPython 3.10+. This stable ABI wheel is less performant than the regular one, but it is compatible with all future Python versions. See PEP 384 for details. https://github.com/light-curve/light-curve-python/issues/79

Changed

  • Build breaking: the only Python build requirement maturin updated from v0.14.x to v1.0 https://github.com/light-curve/light-curve-python/pull/216 https://github.com/light-curve/light-curve-python/pull/215

Fixed

  • Building from sdist on x86-64 macOS required manual setting of $MACOSX_DEPLOYMENT_TARGET to 10.9 or higher. Recent maturin update allowed us to specify it via pyproject.toml

[0.7.2] 2023-04-12

Added

  • Feature transformations via transform constructor keyword. For most of the features it could accept string with a transformation name such as 'arcsinh' or 'clipped_lg', True or 'default' for the default transformation, None or False for no transformation https://github.com/light-curve/light-curve-python/issues/184 https://github.com/light-curve/light-curve-python/pull/188
  • Binary wheels for x86_64 Windows built with no Ceres nor GSL features https://github.com/light-curve/light-curve-python/issues/12 https://github.com/light-curve/light-curve-python/pull/185
  • enum-iterator crate dependency https://github.com/light-curve/light-curve-python/pull/188
  • CI: code coverage with codecov https://github.com/light-curve/light-curve-python/pull/197
  • Development: now project has extras for testing (test) and development (dev) https://github.com/light-curve/light-curve-python/pull/197

Changed

  • Build breaking: minimum supported Rust version (MSRV) is bump from 1.60 to 1.62
  • Bump light-curve-feature 0.5.4 -> 0.5.5
  • Bump pyO3 0.18.1 -> 0.18.2
  • Most of the parametric features have default values for their parameters now, which, due to pyO3 limitations, are not presented in the signatures, but documented in the docstrings. It also makes Python and Rust implementations more consistent https://github.com/light-curve/light-curve-python/issues/194 https://github.com/light-curve/light-curve-python/pull/195
  • Development: switch from pytest-markdown to markdown-pytest which allowed us to use up-to-date pytest https://github.com/light-curve/light-curve-python/pull/198

Deprecated

  • BazinFit and VillarFit constructors will not accept None for mcmc_niter, ceres_niter, and lmsder_niter arguments in the future, just do not specify them to use defaults instead. https://github.com/light-curve/light-curve-python/pull/195
  • Periodogram constructor will not accept None for peaks, resolution, max_freq_factor, nyquist and fast in the future, just do not specify them to use defaults instead. https://github.com/light-curve/light-curve-python/pull/195

Fixed

  • Bins feature had non-optimal lower boundary check for time series length: it checked if it is at least unity for any underlying features. Now it takes underlying feature requirements into account. It was fixed by updating light-curve-feature to v0.5.5.

[0.7.1] 2023-03-17

Fixed

  • Bug introduced in v0.6.5: *Fit.model(t, params) wrongly checked t and params arrays to have the same length

[0.7.0] 2023-03-16

Added

  • BazinFit and VillarFit have got ceres and mcmc-ceres algorithms using Ceres Solver as a non-linear least squares optimizer. ceres is found to be more robust than lmsder algorithm ( available via gsl Cargo feature) but working roughly twice slower. Ceres can be built from source (ceres-source Cargo feature, enabled by default in Cargo.toml) or linked to system library (ceres-system Cargo feature, enabled for cibuildwheel in pyproject.toml)

Changed

  • API breaking: Features' __call__() signature changed to make sorted=None, check=True and fill_value=None arguments to be keyword-only
  • API breaking: Features' many() signature changed to make all arguments but the first lcs to be keyword-only
  • API breaking: Bins constructor signature changed to make offset and window arguments to be keyword-only. For Rust implementation __getnewargs__ is replaced with __getnewargs_ex__. Please note that for the specific case of Python implementation and Python version < 3.10, Bins still accepts positional arguments
  • API breaking: BazinFit and VillarFit constructor signatures changed to make everything but the first lcs argument to be keyword-only
  • API breaking: Periodogram constructor signature changed to make all arguments to be keyword-only
  • API breaking: DmDt constructor signature changed to make all arguments but dt and dm to be keyword-only, __getnewargs__ is replaced with __getnewargs_ex__. DmDt.from_borders class-method constructor has all arguments to be keyword-only
  • API breaking: DmDt methods' signatures changed to make all arguments but data (like t, t, m or lcs) to be keyword-only
  • Build breaking: building with Ceres Solver (ceres-source Cargo feature) is now a default, and potentially could break a building pipeline in some cases. If you want to build without Ceres Solver, you need to explicitly disable default features with --no-default-features maturin flag
  • CI: switch from macos-11 to macos-latest for testing
  • Bump pyo3 0.17.3 -> 0.18.1
  • Bump rust-numpy 0.17.2 -> 0.18.0

Removed

  • Build breaking: fftw-static, fftw-dynamic, mkl Cargo features are removed after deprecation in v0.6.2 and replaced with fftw-source, fftw-system and fftw-mkl.

Fixed

  • Bug introduced in v0.6.5: *Fit.model(t, params) wrongly checked t and params arrays to have the same length

[0.6.5] 2023-02-22

Fixed

Added

  • Initial copy and pickle (minimum protocol version is 2) support for feature extractors and DmDt https://github.com/light-curve/light-curve-python/issues/103 https://github.com/light-curve/light-curve-python/pull/145 https://github.com/light-curve/light-curve-python/pull/150
  • serde v1 and serde-pickle v1 Rust dependencies. serde-pickle is an arbitrary choice of a (de) serialization binary format, but it could be useful in the future having a way to inspect Rust structures from Python https://github.com/light-curve/light-curve-python/pull/145

Changed

  • Build environment: minimum support Rust version (MSRV) is bumped 1.57 -> 1.60
  • Bump light-curve-dmdt 0.6.0 -> 0.7.1

Fixed

  • BazinFit and VillarFit docs are clarified for .model() and ln_prior usage https://github.com/light-curve/light-curve-python/issues/125 https://github.com/light-curve/light-curve-python/pull/146

  • rust-numpy 0.16.2 -> 0.17.2
  • CI: binary wheels are now built using our custom manylinux/musllinux images, which include FFTW library optimised to use platform-specific SIMD instructions. It should give up to 50% performance gain for Periodogram at all Linux platforms but x86_64 where we use MKL https://github.com/light-curve/light-curve-python/pull/134
  • We don't provide binary wheels for Linux i686 anymore, please contact us if you need them https://github.com/light-curve/light-curve-python/pull/134
  • wheel build dependency: maturin 0.13.x -> 0.14.x https://github.com/light-curve/light-curve-python/issues/130 https://github.com/light-curve/light-curve-python/pull/135
