- v3.3 - 2026/04/10 - Adaptive gradients differentiated for each parameter in Levenberg-Marquardt fitting. Anomaly detection code to trigger initial conditions with additional lenses (thanks to Antonio Consiglio). Triple-lens fitting (only from anomalies on binary lens models) in static configuration, including parallax and/or orbital motion. Reader lists the datasets used distiguishing those taken from ground or from a satellite. Efficiency much higher than previous versions.
- v3.2 - 2025/11/17 - Scatter assessment in data pre-processing upgraded to second order and using median residual. Input in fluxes now also allowed. Optimizations in LevMar using more accurate gradients. Bug fixed in ModelSelector for planetary initial conditions from parallax models. Bug fixed in InitCond for initial conditions based on asymmetry. Re-activated stepchain mode in RTModel.
- v3.1 - 2025/08/21 - Upgraded to VBMicrolensing 5.3: parallax calculations based on lookup table. Corrected a bug in LevMar and removed an ambiguous reference for compilation in c++23. Slight revision of bumping mechanism. Corrected small bug in plotmodel.
- v3.0 - 2025/06/19 - Astrophotometric fits and Image-constrained fits with deep re-structuring of the whole code. Possibility to change parameters ranges in fits; possibility to fit for binary systems with dark companions or change mass-luminosity-radius relations. plotmodel updated with plots for centroid trajectory. A few bugs corrected in Reader, with peak season identified by consecutive positive deviations.
- v2.4.2 - 2025/05/08 - Corrected a bug causing hanging in the call to InitCond for nostatic.
- v2.4.1 - 2025/04/26 - Corrected a bug in Reader for otherseasons=2; satellite datasets only end up with numbers; Corrected a bug in plotmodel.
- v2.4 - 2025/02/10 - Automatic detection of existing installation of VBMicrolensing at build time; Output of failing subprocesses shown for easy error detection; Bug correction in automatic cleanup of preliminary models; Lower boundary of q decreased to 1.e-7; Refinement of offset degeneracy calculation; New function in plotmodel to convert from fitting parameters to conventional orbital elements; plotmodel includes limb darkening in calculation of residuals.
- v2.3 - 2024/11/28 - Update to VBMicrolensing 4.1.2; minor bug in re-normalization; additional accurate initial conditions for planetary events; check each binary-lens fit for offset degeneracy; changed maximal steps in each parameter in LevMar; a few bugs corrected in covariance reports; ellipsoid increased by delta chi square and more accurate check of duplicates in model selection; models above Wilks' theorem trheshold are removed in Finalizer; accuracy option in plotmodel; source trajectory and caustic in templates.show_template().
- v2.2 - 2024/10/25 - Replaced VBBinaryLensing with VBMicrolensing; Added the possibility to constrain fits; possibility to choose model categories to fit; possibility to make just a quick update to previously found models; added Keplerian orbital motion for binary lenses as model category "LK"; partial implementation of static triple-lenses, triple-lenses with parallax; optimization of ModelSelector excluding higher chi square models from check; possibility to cleanup event directory from preliminary models, thus saving 99% disk space.
- v2.1.1 - 2024/09/11 - Re-ordering peaks in InitCond to promote peaks appearing in more datasets.
- v2.1 - 2024/09/04 - recover_options function; noparallax replaced by onlyorbital everywhere; InitCond prints peaks found; All peaks used for single-lens-single-source initial conditions; Templates package to manage template library; Time limit for LevMar now forced by RTModel; Possibility to start fit from user-defined initial conditions through an array or a file; plotmodel: figure, showlightcurve, showcaustics.
- v2.0.7 - 2024/07/23 - Corrected a bug in ModelSelector showing up for events with a single dataset; corrected a minor bug in re-using old models for PS category.
- v2.0.6 - 2024/06/10 - Corrected a few bugs on satellites and initial conditions
- v2.0 - 2024/04/10 - First public release
