Pastas version 0.13.0 has just been released. This version includes large improvement to the solver methods, including a start on an uncertainty quantification framework within Pastas.

This release should be mostly backward compatible.

**Full Changelog**: https://github.com/pastas/pastas/compare/v0.11.0...v0.12.0

For this release we focused on fixing bugs and adding tests to the code to improve code quality. This version of Pastas should be mostly compatible with the previous versions of Pastas.

This release adds a couple of new features to pastas, along which a new stressmodel to simulate groundwater recharge (Still work in process) and two new response functions. The example notebooks have been updated and a couple of new ones added.

Category | Explanation
-- | --
Enhanced | Initial parameters of scaling parameter are based on std
Enhanced | Example notebook are automatically rendered for ReadTheDocs
New | New example notebook with a groundwater well
New | Four Parameters response function added (FourParam)
New | Double Exponential response function added (DoubleExponential)
New | Example notebook with synthetic data and a noisemodel added
New | A new stressmodel for the simulation of recharge is introduced (RechargeModel).

Mostly a bug fix release, with many minor bugs fixed. This version should be mostly backward compatible.

Category | Explanation
-- | --
Enhanced | Fit_report is now scaled automatically
Enhanced | Bug in calculating the tmax for the response functions fixed
New | Added a utility to get the tmin and tmax where all stresses have values

Pastas version 0.9.8 has been released. This version should be mostly backward compatible with 0.9.7. The focus of this version was on bug fixes and clean up of the model code.

Category | Explanation
-- | --
Enhanced | the nparam attribute from a stressmodel is now a property.
Enhanced | Warning is provided when NaN-values are removed from residual or simulation series
Enhanced | Pastas version is updated when saving an pastas model loaded from an old file
New Feature | ml.add_stressmodels can now take multiple stressmodels at once
Deprecated | Theis response function has been removed.
