0.2.1 (2019-09-26)

Adds a new interface for tuning dense mass matrices with less overhead
Adds support for photodynamics using rebound
Adds a new interface for assigning units to Theano variables
Adds new physically-motivated distributions for impact parameter and eccentricity
Improves test coverage
Fixes bug in diagonal elements of the IntegratedTerm model
Fixes bug in indexing for TTVOrbit models with large TTVs

0.2.0 (2019-08-04)

Updates starry to get much better performance for high order spherical harmonics
Renames StarryLightCurve to LimbDarkLightCurve
Restructures the C++ backend to reduce code duplication
Adds support for fitting of astrometric observations
Adds support for exposure time integration in celerite models
Adds new distributions for periodic parameters and U(0, 1).
Fixes many small bugs

0.1.6 (2019-04-24)

Fixes some edge case failures for Kepler solver
Improves reliability of contact point solver and fails (more) gracefully when this doesn't work; this reduces the number of divergences when fitting a transit model

0.1.5 (2019-03-07)

Improves contact point solver using companion matrix to solve quadratic
Improves reliability of Angle distribution when the value of the angle is well constrained

0.1.4 (2019-02-10)

Improves the reliability of the PyMC3Sampler
Adds a new optimize function since the find_MAP method in PyMC3 is deprecated
Adds cronjob script for automatically updating tutorials.

0.1.3 (2019-01-09)

Adds a more robust and faster Kepler solver (ref)
Fixes minor behavioral bugs in PyMC3 sampler wrapper

0.1.2 (2018-12-13)

Adds regular grid interpolation Op for Theano
Fixes major bug in handling of the stellar radius for transits
Fixes small bugs in packaging and installation
Fixes handling of diagonal covariances in PyMC3Sampler

0.1.1 (IPO; 2018-12-06)
