v0.4.0

• #366 prepares changes log for next release (@segsell)
• #362 polishes documentation and adds copy button for code-snippets (@segsell)

v0.3.4

• #361 fixes multiple bugs in estimate_msm and estimate_ml that only happened in constrained estimations (@timmens, @janosg, @segsell)
• #347 adds a BootstrapResult object similar to other estimation results (@segsell)

v0.3.3

• #359 Improves error handling with violated constaints @timmens
• #358 Improves cartis roberts set of test functions and improves the default latex rendering of MultiIndex tables @mpetrosian

v0.3.2

Polishing and multiple small bugfixes.

v0.3.1

This is the first version of estimagic with experimental support for nonlinear constraints. Moreover, we fix some bugs and improve test coverage.

• #349 fixes bugs introduced in the transition to pytrees and custom results objects. Details are described in the PR comments.
• #346 Adds experimental support for nonlinear constraints

v0.3.0

Summary

Fist release with pytree support in optimization, estimation and differentiation
and much better result objects in optimization and estimation.

Breaking changes

• New OptimizeResult object is returned by maximize and minimize. This
  breaks all code that expects the old result dictionary. Usage of the new result is
  explained in the getting started tutorial on optimization.
• New internal optimizer interface that can break optimization with custom optimizers
• The inferface of process_constraints changed quite drastically. This breaks
  code that used process_constraints to get the number of free parameters or check
  if constraints are valid. There are new high level functions
  estimagic.check_constraints and estimagic.count_free_params instead.
• Some functions from estimagic.logging.read_log are removed and replaced by
  estimagic.OptimizeLogReader.
• Convenience functions to create namedtuples are removed from estimagic.utilities.

v0.2.4

Remove chaospy as dependency

v0.2.3

• Pytree support for first and second derivative
• Add fast solvers for quadratic trustregion subproblems
• Improved estimation tables
• Various small bugfixes

v0.2.2

First release with own optimization algorithms.

• parallel Nelder-Mead by Jacek Barszczewski
• parallel Pounders by Sebastian Gsell

The algorithms are still work in progress and will get more convergence criteria, support for bounds, etc. in the future.

v0.2.1

Mainly improvements to the documentation.
