Fides 0.7.8

• Replaced setup.py with pyproject.toml
• added pre-commit hooks for isort & black and applied formatting to all files

Fides 0.7.7

• drop support for python 3.7 and 3.8
• decrease logging verbosity for successful runs

Fides 0.7.6

• adds license and other metadata to setup.py, thanks to @drhagen

Fides 0.7.5

• Adds a notebook containing a short tutorial to use fides for general purpose optimization.
• Slims logging output such that it nicely fits into a single line in jupyter notebooks
• Refactors a trust region radius updating
• Fixes a bug in the convergence check for absolute/relative function tolerance

Fides 0.7.4

• Fixes affine scaling for bounded problem. This fixes a critical bug introduced in 0.7.2, updating is strongly recommended

Full Changelog: 0.7.3...0.7.4

Fides 0.7.3

• reenables specification of stepback and subspace strategies via appropriate strings

Fides 0.7.2

• adds additional option value type validation
• fixes runtime warning for unbounded problems
• fixes optimization based stepback mode refined

Fides 0.7.1

• Fixes a bug in tracking that incorrectly indicated non-updating in hessian approximation
• Fixes a bug where curvature condition in BFGS approximation was not ignored even when corresponding option was enabled
• Fix subspace normalization for cases when newton step was within trust region radius
• Extend tracing by condition numbers

Fides 0.7.0

• Add option to track history of optimization for detailed debugging
• Add options to customize BFGS (and derived) approximation schemes by ignoring curvature condition
• Add novel hybrid method that switches approximations based on fraction of steps with inconclusive trust region ratio
• Remove option to include scaled gradient as candidate step
• Refactor step refinement and restrict it to subspace of base step
• Reduce logging output verbosity

Fides 0.6.3

• simplify and fix structured secant method based hybrid schemes
• removes the PSB approximation scheme
