* Add ``linopy.piecewise()`` to create piecewise linear function descriptors (`PiecewiseExpression`) from separate x/y breakpoint arrays.
* Add ``linopy.breakpoints()`` factory for convenient breakpoint construction from lists, Series, DataFrames, DataArrays, or dicts. Supports slopes mode.
* Add ``linopy.segments()`` factory for disjunctive (disconnected) breakpoints.
* Add ``active`` parameter to ``piecewise()`` for gating piecewise linear functions with a binary variable (e.g. unit commitment). Supported for incremental, SOS2, and disjunctive methods.
* Add the `sphinx-copybutton` to the documentation
* Add SOS1 and SOS2 reformulations for solvers not supporting them.
