Light-curve-python

Added

- `PeakToPeakVar` experimental feature https://github.com/light-curve/light-curve-python/pull/332

Changed

- Bump `pyO3` to 0.21
- Bump `rust-numpy` to 0.21
- "abi3" is a default Cargo feature now

Removed

- Stop publishing PyPy wheels to PyPI. We still publish all CPython wheels we published
previously https://github.com/light-curve/light-curve-python/issues/345 https://github.com/light-curve/light-curve-python/pull/347

Fixed

- Bug which prevents initialization of Rust's `*Fit` features if compiled without Ceres or GSL (our PyPi Windows
wheels) https://github.com/light-curve/light-curve-python/issues/343 https://github.com/light-curve/light-curve-python/pull/344

Added

- `Roms` (robust median statistics) experimental feature, a variability index based on the deviation of observations
from the median. https://github.com/light-curve/light-curve-python/pull/315 Thanks GaluTi for their first
contribution

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/327
- **Breaking**: stop supporting Python 3.7 https://github.com/light-curve/light-curve-python/pull/282
- We stop distributing CPython wheels for specific Python versions, now we distribute ABI3 wheels which are compatible
with all future Python versions

Deprecated

Removed

- **Build breaking**: `abi311` Cargo feature is removed, now we plan to have `abi3` feature only, which would correspond
to the minimum supported Python version. Feel free to use `pyo3/abi3..` features directly for newer ABI versions.

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

Added

- `RainbowRisingFit` experimental feature, https://github.com/light-curve/light-curve-python/pull/278
by [erusseil](https://github.com/erusseil)

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
- Bump `pyO3` 0.18.3 -> 0.19.1, it simplified signature generations for
classes https://github.com/light-curve/light-curve-python/pull/230
- Bump `rust-numpy` 0.18.0 -> 0.19.0 https://github.com/light-curve/light-curve-python/pull/230
- Bump `enum-iterator` 1.2.0 -> 1.4.1 https://github.com/light-curve/light-curve-python/pull/233
- Bump `thiserror` 1.0.41 -> 1.0.48 https://github.com/light-curve/light-curve-python/pull/242

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](https://www.python.org/dev/peps/pep-0384/) 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
- CI: bump cibuildwheel to 2.13.1 https://github.com/light-curve/light-curve-python/pull/225
- Bump `itertools` 0.10.5 -> 0.11.0 https://github.com/light-curve/light-curve-python/pull/224
- Bump `pyO3` 0.18.2 -> 0.18.3 https://github.com/light-curve/light-curve-python/pull/207

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`
