Changelog ++++++++++ .. next release **(next release)** - Dropped support for Python 3.9, keeping up with jaxoplanet for testing. - Added pre-commit requirements, most notably the ruff linter to check for common python code style issues. Many flags still not checked, especially those related to docstrings. - Switched to uv for dependency management, not yet building though. **0.3.1 (10/2024)** - Enforced forward-mode differentiation under the hood in ``OblateSystem`` to speed up gradient evaluation for ``OblateSystem.loglike`` or any functions that use ``OblateSystem.lightcurve``. **0.3.0 (10/2024)** - Added ``limb_darkening_laws`` module, which contains convenience functions for transforming limb darkening coefficients of commonly used limb darkening laws into coefficients of high-order polynomials that ``squishyplanet`` can use to model the intensity profile of the star. **0.2.2 (09/2024)** - Added ability to parameterize the planet's orbit via t0, the time of transit center, instead of t_peri. This is useful for fitting systems with non-zero eccentricity. **0.2.1 (09/2024)** - Fixes issues `#16 `_ and `#17 `_. **0.2.0 (08/2024)** - The ``log_jitter`` term now represents the *standard deviation* of the added noise, not the variance. This brings it in line with the definition of measurement uncertainties. - When dealing with a projected 2D ellipse (i.e., not a tidally locked planet) ``projected_r`` has been replaced with ``projected_effective_r``. Previously there was a strong degeneracy between ``projected_r`` and ``projected_f``, since the combination of the two dictated the area of the ellipse, and therefore transit depth, which fits are much more sensitive to than to slight deviations to ingress/egress shape. ``projected_effective_r`` is the radius of a circle with the same area as the ellipse, and is therefore a more physically meaningful parameter to fit for. - Added fit_limb_darkening_profile() as a convenience function for approximating limb darkening profiles computed via stellar grids as high-order polynomial laws that ``squishyplanet`` can use. - ``tidally_locked`` is now a required parameter when creating an ``OblateSystem`` object, which is a change from its previous default of True. **0.1.2 (05/2024)** Fixed issue `#7 `_. Previously, calls to ``OblateSystem.lightcurve()`` after initializing the ``OblateSystem`` object were not recalculating true anomalies even if the ``period`` and/or ``t_peri`` changed. **0.1.1 (05/2024)** Initial JOSS submission version, fixed issues #1 and #5.
