v0.0.13

New Features

• The function LinearExpression.from_tuples now allows ScalarVariable as input.
• For compatibility reasons, the function groupby_sum now allows pandas.Series as input.

Bug Fixes

• Filtering out zeros is now an optional feature in the solve function. The previous behavior of filtering just before the LP file writing, lead to unexpected errors for constraints with only zero terms.

v0.0.12

New Features

• A new module was created to export basic mathematical quantities such as lb, ub, c vectors and the A matrix. Use it with the matrices accessor in linopy.Model.
• For Constraints`` and Variables`` a ipython autocompletion function for getting items was added.
• Inplace updates for constraints are now more flexible.
• AnonymousConstraint can now built from comparison operations of variables with constants, e.g. x >= 5.
• The Model.add_constraints function now support input of type ScalarVariable, ScalarLinearExpression and ScalarConstraint.
• Terms with zero coefficient are now filtered out before writing to file to avoid unnecessary overhead.
• The function sanitize_zeros was added to Constraints. Use this to filter out zero coefficient terms.

Bug Fixes

• Solving with gurobi and io_api="direct" lead to wrong objective assignment if the objective contained non-unique variables. This is fixed in this version.

v0.0.11

This release introduces new features related to expression creation and comes with an improved documentation.
Due to some indexing bugs in the latest xarray package v2022.06., the xarray depedency was fixed to maximally v2022.03.

v0.0.10

See release notes for details.
